"The ship did not leave because of what arrived. It left because of what was already here. Two hundred years later, it came back to find the same thing waiting." -- Traveler // Operator Tactics Universe

00 The Traveler Introduction

The UNSO Traveler is a generation ship in low Earth orbit. Four hundred meters in diameter. Six hundred inhabitants. Two hundred years of isolation. It entered orbit in 2060 and within forty-eight hours every faction on Earth had made contact. None of them knew what they were dealing with.

The ship launched in 2024 carrying twenty children and six adult Mentors, funded by pre-Upheaval consortium capital, powered by a CFR-4 Cold Fusion reactor of revolutionary design. The Mentors died in the third week. The children ran the ship. They built a governance structure, a culture, a population, and a coexistence arrangement with the gene-forged variants that escaped containment in year eighty.

They are not grateful to be found. They are a sovereign entity in a ship. They have been running their own governance for five generations. The concept of being rescued does not map onto their experience, because from their perspective they were never lost.

How It Fits Into OT Traveler does not replace standard OT missions. It adds a contested zone that moves. The ship sits at 412 kilometers altitude, moving at 7.6 km/s. Every faction wants what is inside it. Your operators go in before the first unauthorized boarding party makes contact. The situation window is seventy-two hours.

01 The Long Loop Setting

The ship was meant for Alpha Centauri. It went somewhere else instead.

A missile from a faction proxy skirmish caught the hull on the way out of Earth's orbital space. Minor damage, the technicians said. Auto-seal contained the breach. The hydraulic flange alignment system was not redundant. A micro-fracture in the primary hydraulic trunk went undetected.

When the ship executed its planned mid-course flip, the attitude control computers logged a successful maneuver. The flanges had not reached correct alignment. Instead of subtracting velocity, the ship added it. The reciprocal course established itself silently, accumulating over decades, carrying the Traveler in a vast arc through deep space that would bring it back toward its point of origin.

Nobody noticed because nobody read the navigation manual. The computers said the course was correct. The algorithm was wrong.

The Mentors

Six adults. Dead in the third week. Hull breach in their section, pressure loss, auto-seal forty seconds too late. Twenty children ran the ship from that point forward in cryo rotations, two awake at a time for twelve-year cycles.

The Breeding Annex

Below Engineering, on a sub-deck that did not appear in mission briefing materials. Automated gene-forge systems running for a century before containment failed. Apex predators, pack hunters, corvids with expanded cognitive architecture. Designed to seed an alien biosphere. The containment failed in year eighty. The animals got out. They have been evolving for a hundred and twenty years since.

The Correction

Finn Adams identified the course variance with a drafting compass and two hundred years of stellar chart data. He calculated a slingshot maneuver around rogue planetoid OSP-14, through a periapsis corridor the ship's structural tolerances barely allowed. The maneuver worked. The great loop closed.

The UNSO Traveler entered Earth orbit in 2060. What it found was not the world it left.

The factions had hardened. The gene-forge programs had proliferated. The arcology towers had risen above the flood lines. The water class system was entrenched. And somewhere in faction data archives, buried under layers of classification, was the record of what the Traveler carried, who had funded it, and whose children were aboard.

02 The Ship as Operational Environment Operations

The Traveler is a layered sphere approximately four hundred meters in diameter with a scaffold spine extending aft to the main engine assembly and a twelve-kilometer solar sail. The sphere divides into three operational zones. Movement through the ship is three-dimensional. The curved deck plates mean standard building-clearance protocols do not apply. Gravity changes by deck and section. Sound carries wrong through the hull material. The Travelers know all of this. Operators going in without a guide will find out the hard way.

Zone	Depth	Control	Threat Level	Key Decks
One: Outer Hull	Surface to ~15% inward	Aberrant sovereign	Extreme	Mentor Section debris field
Two: Mid-Sphere	15% to ~70% inward	Contested	High	Bridge (C), Storage (D), Library (E), Engineering (G)
Three: Inner Core	Center mass	Traveler sovereign	Low (by invitation)	Living Quarters (F), Arboretum (I)

Z1 Zone One: The Outer Hull Aberrant Territory

Dark. Cold. Wrong. The Aberrants were here before any living Traveler. They built something in the maintenance corridors. You are the intruder.

GravityAbsent or inverted. GravPot hardware repurposed by five generations of animals that do not understand what it was for.

LightNone. Aberrant bioluminescent markers only. They glow at a frequency that registers wrong in human visual processing.

TemperatureWell below operational threshold.

CommsDark zone. No relay coverage.

Traveler PresenceArmed patrol perimeter at zone boundary only.

The bioluminescent markers are not decoration. They are a territorial language. Walking through them without knowing what they say is how operators disappear.

The Traveler Council considers the outer hull Aberrant sovereign territory. They will not send recovery teams if operators go in uninvited.

What Operators Come Here For The Mentor Section debris field holds original mission briefing materials, including classified Breeding Annex documentation never transmitted to Earth. Pre-Upheaval data, intact. Every faction with a genetics program wants it. The outer hull also contains maintenance access to CFR-4 reactor sub-systems. The Travelers have mined three of the four approach corridors. They did not mark which three.

Read Aloud The airlock cycles open and the temperature drops fifteen degrees in the space of a breath. Your headlamp catches dust motes drifting sideways -- not falling, drifting -- because the GravPot plates are pulling in directions that have nothing to do with down. The corridor ahead is dark. Not the dark of a power failure. The dark of a place that has not had light in it for a very long time. Something on the walls glows a frequency your eyes do not want to process. The smell is ozone layered over something wet and organic. Behind you, the airlock seals shut with a sound that is quieter than it should be.

Under-System // What Keeps Zone One Running Nothing keeps Zone One running. The environmental systems failed decades ago. The hull maintains structural integrity through passive engineering -- thick metal, redundant seals, two centuries of micro-repairs by creatures that understand the ship as territory rather than technology. The GravPot plates still draw power from the reactor grid but respond to no human input. The Aberrants have repurposed them through a process that looks like instinct but might not be. Air circulation is passive convection from warmer zones. If the reactor fails, Zone One loses thermal bleed within hours and drops to deep-space ambient. The Aberrants would survive. Operators would not.

Haecceity Texture // Zone One Sound: Hull creaks arrive from directions that do not correspond to the ship's structural members. The metal is settling around something. Light: Bioluminescent markers pulse at 0.3 Hz -- just below conscious visual rhythm. Gene-forged operators report a sense of being watched that baseline operators do not. Air: Stale. Recycled through biological processes rather than mechanical filtration. Tastes like copper pennies left in standing water. Temperature: Cold enough to see breath. Colder in corners. The cold moves. Biological wrongness: Organic residue on corridor walls that is warm to the touch. It was not there an hour ago. It will not be there in an hour. Gravity: Changes mid-stride without warning. The inner ear adjusts before the conscious mind does, producing a dissociative lurch that experienced Travelers call "the drift."

Zone One Shift Encounters (d6)

The bioluminescent markers in a thirty-meter stretch go dark simultaneously. Fifteen seconds of total blackness. When they return, the pattern has changed. Something passed through.

A single Pack member stands in the corridor ahead, unmoving. It is not blocking the path. It is standing on a maintenance hatch that someone -- or something -- sealed from below.

Organic material on the wall has been arranged. Not randomly. In parallel lines with consistent spacing. It resembles a notation system. Wren Callo-Finn would want to see this.

A Stalker carcass, fresh. Killed by another Stalker. The territorial markings around the body are new. Something in the hierarchy shifted overnight.

Gravity reverses in a six-meter section without warning. Operators fall upward. The GravPot plates hum at a frequency that makes teeth ache. Lasts 2d6 rounds.

A maintenance corridor that was sealed last visit is now open. The seal was not cut -- it was dissolved. The corridor beyond smells wrong. Warm air comes from inside.

Site Clocks -- Zone One

Marker Drift

4-segment. The bioluminescent territorial markers are shifting inward, toward the mid-sphere boundary. Each segment: markers advance ~20 meters. When full, the Aberrant territorial line has moved and the Travelers' patrol perimeter is inside Aberrant-claimed space.

Hull Integrity

6-segment. Micro-fractures in the outer hull plating accumulate from thermal cycling and two centuries of micro-impacts. Advance when operators force sealed passages, when Stalker combat damages structural members, or when GravPot plates overload. At 6: hull breach. Automatic seal -- if it works.

Zone One Salvage (d6)

Pre-Upheaval sealed document case. Contents: mission briefing addendum referencing the Breeding Annex by a different name. Worth significant faction interest.

CFR-4 diagnostic module, non-functional but containing calibration data Dav Anker would trade for. Heavily corroded.

Mentor personal effects. Photographs, handwritten notes, a child's drawing labeled with a name that matches a current Traveler family line.

Gene-forge containment hardware, intact. The locking mechanism uses a frequency key. The Corvids react to the frequency when it is activated.

Navigation instruments from the Adams workspace. Hand tools, star charts with hand-corrections. The corrections are accurate. The handwriting belongs to someone who was twelve years old.

Nothing salvageable. But the search disturbs something organic growing behind a wall panel. It retracts from light. It was not here last cycle.

When It Goes Wrong

Operators who overstay in Zone One -- more than four hours without Traveler escort -- trigger a territorial cascade. The Pack stops holding junctions and begins active pursuit. Stalker pairs converge on the operators' last known position. The Corvids overhead go silent, which is the last warning before coordinated hunting behavior begins. Retreat to the mid-sphere boundary is the only survivable option. The Travelers will not open the boundary airlocks for operators who caused the cascade. Finding an alternate route out is DC 16 INT and takes 1d4 rounds of searching while being hunted.

GM Tip // Running Zone One Zone One is a horror zone. Run it slow. Describe what operators hear before what they see. Let the players sit in the silence between sounds. The Aberrants are not jump scares -- they are the growing certainty that something is watching and has been watching since the airlock closed. Ask players what their operators are doing with their hands. Ask if they are breathing through their mouths or their noses. The air tastes different depending on the answer.

Z2 Zone Two: The Mid-Sphere Contested

The contested layer. The Travelers patrol it. The Aberrants probe it. The factions want everything in it. Operators work here by default.

BridgeDeck C. The Captain runs command rotations here. Does not take unscheduled visitors.

Storage CoreDeck D. Two centuries of equipment in varying states of function.

LibraryDeck E. Primary cultural and technical archive. Council clearance required for restricted sections.

EngineeringDeck G. CFR-4 reactor stacks. Most defended location outside the inner core.

SecurityArmed patrols, rotating 12-hour shifts. Operators without escort will be detained. Third offense: returned to shuttle dock without negotiation.

The Breeding Annex Below Engineering. A sub-deck that does not appear on any map the Travelers share with outside parties. Automated systems, still running. Gene-forge stock manifests, species engineering records, and the complete evolutionary dataset from the Aberrant breach forward. This is what the genetics factions actually want. The Cold Fusion data is leverage. The Annex records are the prize.

Read Aloud The mid-sphere corridor is lit -- barely. Strip lighting runs along the deck seams, casting everything in flat institutional white that makes distances hard to judge. The air is warmer here, recycled and re-recycled until it carries a permanent undertaste of metal and growing things. Somewhere above, through three meters of hull plating, the reactor hums at a frequency you feel in your sternum rather than hear. Traveler crew pass in pairs, eyes forward, acknowledging nothing. The walls are marked with generation-count tallies scratched into the paint. Five sets of marks. Two hundred years of people counting how long they have been inside.

Under-System // What Keeps Zone Two Running Zone Two runs on the CFR-4 reactor grid and two centuries of improvised maintenance. The environmental systems are original hardware patched with Traveler-fabricated components that do not quite match specification. Air filtration cycles every eighteen minutes -- operators can hear the pressure differential change if they listen. Lighting is 60% original, 40% jury-rigged from salvaged components. The strip lighting flickers on a predictable twelve-second cycle that experienced Travelers ignore and newcomers find disorienting. Water recycling runs through Engineering on Deck G. The system is at 94% efficiency, which means 6% loss per cycle, which means the Travelers have been slowly losing water for two hundred years. They know. They do not discuss it with outsiders.

Haecceity Texture // Zone Two Sound: The reactor hum is omnipresent. Operators stop noticing it after forty minutes. When they leave the ship, the silence is worse. Light: Flat white strips with a twelve-second flicker cycle. Shadows are short and hard-edged. No natural light anywhere. Air: Warm, humid, faintly metallic. Changes character near Engineering -- hotter, drier, with an ozone edge. Near the Library, the air carries old paper smell from physical archives. Temperature: 22C standard, dropping to 18C near zone boundaries. The temperature gradient is how experienced operators navigate without maps. Biological wrongness: Scratch marks on corridor walls at heights that do not correspond to any Traveler. Pack probe marks. Fresh ones mean the Breach Clock is advancing. Human texture: Children's drawings taped to corridor walls near Living Quarter access points. Meal schedules posted in handwriting. A communal culture visible in the margins.

Zone Two Shift Encounters (d6)

A Traveler child, maybe nine years old, watching the operators from a maintenance alcove. She is not afraid. She is counting them. She reports to someone.

The strip lighting fails in a forty-meter stretch near Engineering. Emergency lighting activates -- red, pulsing, insufficient. The reactor hum changes pitch for eleven seconds, then returns to normal. Dav Anker does not appear at his station for the next two hours.

A faction operative, not affiliated with the operators' employer, moving through the Library with a Traveler escort that looks coerced. The escort makes eye contact with the operators. Once. Briefly.

Three Pack members at a corridor junction near the zone boundary. They are inside the mid-sphere. The Traveler patrol that should be here is not. The Pack is not advancing. It is holding position, watching the Engineering access corridor.

A maintenance panel in the corridor has been opened from inside the wall. Tools are laid out in a precise line. The work is half-finished. Whoever was here left in a hurry. The tools are Traveler-fabricated but the technique is not.

Sable Oduya, alone, outside a sealed Council chamber at an hour when no session is scheduled. She is listening at the door. She straightens when she sees operators and walks away without speaking.

Site Clocks -- Zone Two

Faction Pressure

6-segment. External faction operatives are probing the mid-sphere with increasing frequency. Advance when: unauthorized faction personnel are detected on-ship (+1), a Council member is compromised (+2), operators act openly on faction business without Traveler cover (+1). When full: Captain Finn-Adelaide suspends all external access. The shuttle dock closes.

Annex Discovery

4-segment. Someone is going to find the Breeding Annex access point below Engineering. Advance when: operators search Engineering sub-levels (+1), faction intel about the Annex reaches the ship (+1), Dav Anker's hydraulic fracture worsens and draws attention to the sub-deck (+1). When full: the access point is found. By someone. Not necessarily the operators.

Zone Two Salvage (d6)

Traveler-fabricated multi-tool. Crude but functional. Designed for reactor maintenance. Dav Anker would recognize the maker's marks.

Library data card, restricted section. Contains partial Breeding Annex species manifest -- twelve entries out of an estimated forty-plus. Enough to confirm the scope.

Storage Core find: pre-Upheaval medical supplies, sealed, still viable. Trade value to the Travelers is significant. They will remember who brought these.

Engineering diagnostic readout, printed on thermal paper. CFR-4 efficiency curves showing a performance anomaly the factions would pay to understand.

A Council member's personal journal, dropped or discarded. Entries describe private meetings with an unnamed external party. The handwriting matches one of the four NPCs.

Pack chemical tracking compound, Traveler-manufactured. One dose. Masks an operator's scent for 8 hours. The Travelers do not give this away. Someone left it here on purpose.

When It Goes Wrong

Operators who burn Traveler trust in Zone Two face compounding consequences. First violation: escort privilege revoked for 24 hours. Second: movement restricted to shuttle dock and designated corridors. Third: returned to shuttle dock and barred from re-entry. There is no fourth. The Travelers do not threaten. They execute administrative decisions with the same efficiency they use for reactor maintenance. Captain Finn-Adelaide does not argue. She signs the paperwork and moves on. Operators who attempt to remain on-ship after ejection will find that the Traveler security response is professional, coordinated, and entirely sufficient.

GM Tip // Running Zone Two Zone Two is a social pressure zone. The threats here are political, not biological. Run it like a workplace where everyone knows something the operators do not. Describe body language -- who looks away, who makes eye contact too long, who stops talking when the operators enter a room. The Travelers are not hostile. They are careful. Two hundred years of living in a sealed container has made them exceptionally good at reading people. Operators who lie will be caught. Operators who are honest about what they want will find the Travelers surprisingly willing to negotiate. The gap between those two outcomes is where the drama lives.

Z3 Zone Three: The Inner Core Traveler Sovereign

Warm. Alive. The place the Travelers actually live. You do not enter without an invitation. Entering without one is an act of war under Traveler law.

Living QuartersDeck F. Six hundred inhabitants across generational family clusters. Shared cooking spaces, communal childcare, a noise culture that manages close quarters.

ArboretumDeck I. A dome twelve kilometers wide filled with trees. The ceiling curves ten stories overhead, transparent. Through it: deep space, raw stars. The Travelers take their meals here. They bring their dead here.

AccessBy Council invitation only. Lose that status and no faction pull will get it back.

Read Aloud The inner core smells like soil and rain. Not recycled-air approximation -- actual soil, turned and composted by hand across generations. The Arboretum dome curves overhead, transparent, and through it the stars are not points of light. They are fields. Dense, unfiltered, raw. The trees are old. Older than anyone aboard. Their root systems have broken through the original deck plating and woven into the ship's structure in ways the engineers stopped trying to correct a century ago. Children run between the trunks. An old woman sits on a bench made from hull plating, eating a meal from a ceramic bowl that was fired in an oven built by people who have never seen Earth. The air is warm and alive and it does not taste like metal. It tastes like a world.

Under-System // What Keeps Zone Three Running The Arboretum ecosystem is the ship's life support. The trees process CO2. The soil biome manages waste cycling. The water table beneath Deck I feeds the roots and cycles through the reactor cooling loop as a secondary heat exchange. This is not a garden. It is the ship's lungs. If the Arboretum fails, the Traveler has approximately ninety days of stored atmospheric reserves before CO2 levels become critical. The Travelers know this. They guard the Arboretum the way a body guards the heart. The transparent dome is the single largest structural vulnerability on the ship -- a direct hit would decompress the core. The Travelers have mounted point-defense systems around the dome rim that they built themselves from salvaged hardware. The targeting solutions are manual. The gunners are sixteen years old.

Haecceity Texture // Zone Three Sound: Birdsong -- not Corvids, actual birds, descendants of a breeding pair brought aboard at launch. Water moving through irrigation channels. Children. Conversation in a creole language that borrows from six Earth tongues and adds words invented aboard. Light: Starlight through the dome, supplemented by grow-lamps on a circadian cycle. The "sunrise" is a warm amber wash that takes twenty minutes to reach full brightness. The "sunset" is faster. The Travelers prefer long mornings. Air: Humid, warm, alive. Photosynthesis-rich. Operators coming from Zone Two will feel lightheaded for the first ten minutes as oxygen levels normalize upward. Temperature: 24C, stable, the most controlled environment on the ship. Biological wrongness: None. This is the one place on the ship that feels right. That is why it is unsettling. After hours in the outer hull, normalcy registers as threat. Gene-forged operators may need a WIS check to stand down. Human texture: Handmade everything. Ceramics, textiles, furniture built from ship materials by people who learned craft through five generations of oral tradition.

Zone Three Shift Encounters (d6)

A Traveler elder approaches the operators during a communal meal and offers to share food. This is a significant social gesture. Refusing is not dangerous but it is remembered. Accepting means sitting with the community for an hour. What the operators learn depends on what they ask.

Wren Callo-Finn is at the Arboretum threshold, staring at a small arrangement of ship components on the deck. She has not moved in twenty minutes. Three Corvids are perched on the dome above her, watching. She will talk if approached but not about the objects.

A Council session is in progress, audible through a partition. Raised voices. The isolationist bloc is making a motion. Sable Oduya exits through a side door, sees the operators, and asks a question she should not be asking outsiders.

The dome point-defense system activates briefly -- a targeting sweep, not a firing solution. The teenage gunner crew scrambles to stations. False alarm. But the sensor log shows something at extreme range that resolved before identification. The Travelers do not share the log.

A child brings the operators a drawing. It depicts the ship from outside, with something attached to the hull that is not part of the ship's structure. The child says a Corvid showed her where to look.

Captain Finn-Adelaide, off-duty, sitting alone at the base of the oldest tree in the Arboretum. She is doing navigation calculations by hand on paper. She does not look up. If operators wait, she will eventually speak -- but only about what she chooses.

Site Clocks -- Zone Three

Council Fracture

6-segment. The isolationist bloc is gaining ground. Advance when: external parties violate Traveler trust (+1), faction operatives are discovered on-ship (+2), the Breeding Annex existence becomes public knowledge (+2), operators act against Traveler interests inside the core (+3). When full: the isolationist bloc wins the Council vote. All external contact ends. The ship moves to a higher orbit.

Corvid Convergence

4-segment. The Corvids are doing something. Wren Callo-Finn tracks it but does not understand it yet. Advance when: Corvid behavioral anomalies are observed (+1), Corvid object arrangements increase in complexity (+1), Corvids begin appearing in locations they have never been seen before (+1). When full: the Corvids do something that changes the Travelers' understanding of what they are. What that means is for the table to decide.

Zone Three Salvage (d6)

Traveler-crafted star chart, hand-illuminated on ship-fabric. Beautiful and accurate. A gift from a Traveler who considers the operators trustworthy. Trade value is zero. Symbolic value is enormous.

Arboretum soil sample containing microorganisms that have evolved in isolation for two centuries. Pharmaceutical applications unknown but potentially significant.

A ceramic bowl, hand-fired, from the communal kiln. Contains residue of a compound the Travelers use for Aberrant chemical masking. The recipe is in the residue if analyzed.

Corvid-left object: a ship component part arranged with three others into a structure that resembles -- but is not quite -- a model of the ship's reactor assembly. Wren Callo-Finn would trade significantly for this.

Council meeting minutes, physical copy, discarded after a session. Contains the current vote count on external trade access. The numbers are not what any faction expects.

Nothing material. But a Traveler elder tells operators a story about the year-eighty breach that does not match the official account. The discrepancy is specific and verifiable.

When It Goes Wrong

Operators who violate inner core sovereignty do not get a warning. They get escorted to the shuttle dock by armed Traveler security, their equipment is confiscated for inspection, and their faction's access status is downgraded by two levels. Captain Finn-Adelaide signs the paperwork personally. If the violation involved the Arboretum, the response is faster and less polite. The teenage point-defense crews are not trained in restraint. They are trained in protection. The distinction matters when operators are standing in the wrong place.

GM Tip // Running Zone Three Zone Three is the emotional core of the supplement. Run it warm. Describe food, conversation, the sound of children who have never known anything but this ship. The Travelers are not tragic. They are complete. They built a functional society in a metal sphere and they are proud of it. The horror is not inside the core -- it is the knowledge that every faction outside wants to take pieces of it. When operators sit in the Arboretum and eat a meal with Travelers, they should feel what is at stake. Not data. Not reactor specs. A world. Small, sealed, irreplaceable. What operators do with that feeling is the real mission.

03 The Travelers as Faction Faction

They are not a faction the way factions are factions. They are a sovereign population inside a ship. Treat them accordingly.

Population

~600

Traveler-born

Council

3 technical, 4 elected

Commander

Cpt. Finn-Adelaide

Navigation Tradition

Reactor

CFR-4

200-year run data

What They Want

Recognition as a sovereign entity
Defined territorial zone in Earth orbit
Guaranteed fresh water and agricultural trading rights
Legal protection for Aberrant specimens under international treaty

What They Will Trade

CFR-4 Cold Fusion technical data - 200-year performance record no faction can replicate in a lab
Breeding Annex records - Two centuries of uncontrolled gene-forge evolution, fully documented
Cultural archive access - On a licensing basis

What They Will Not Trade

The Aberrants as property. The ship. Any acknowledgment that the factions have jurisdiction over Traveler-born citizens.

Vulnerability

Internal Council split between isolationists and pragmatists. The pragmatists need outside trade to survive. The isolationists would rather die clean than compromise. Captain Reeves holds that line by force of reputation.

Faction Escalation Ladder

1FormalThe meeting is acknowledged off the record. The Council stops answering communications.

2SuspendedShuttle dock access suspended. Operators on-ship are guests of the Council, which is a polite way of saying detained.

3MovementThe ship moves. Not dramatically. Just enough to remind all parties that it can.

4LockdownThe Breeding Annex manifests go dark. Every copy encrypted. What the factions want most becomes permanently inaccessible unless the Travelers decide otherwise.

What They Offer Operators Unrestricted mid-sphere movement, Library access, reactor technical consultation, Aberrant behavioral intel, and the credibility that comes from being seen as trusted by the Travelers. What they demand: specific asks only. No open-ended loyalty agreements. They want a thing done.

04 Aberrant Threat Matrix Threats

They are not monsters. They are two hundred years of selection pressure in a closed metal sphere with limited prey, no natural light in the outer sections, and the intermittent presence of human beings who could sometimes be caught. Plan accordingly.

The Stalker

Gene-Forged Apex Predator - Outer Hull / Mid-Sphere Perimeter

HP 18 AC 14 Speed: Fast (enclosed spaces)

Attack: Lunge +6 to hit, 2d6+3 dmg. On hit: target Pinned.

Origin: Big-cat derivative. Five limbs: four locomotion, one vestigial with grip function. Compound eye clusters.

Pinned

Target cannot move. Each round, Stalker auto-hits for 1d6 damage unless target breaks free (DC 14 STR, action) or ally pulls them clear (DC 12 STR, action).

Coordinated Hunt

Stalkers hunt in pairs. First drives prey toward the second. If two present, the second always has advantage on its first attack.

Silent Approach

Cannot be heard approaching. Only warning: bioluminescent marker smell (ozone and something organic). DC 12 Perception if watching for it. No check if distracted.

Compound Eyes

Cannot be flanked. Advantage on Perception. Unaffected by darkness.

The Pack

Gene-Forged Territorial Predator - Outer Hull

HP 12 (per individual) AC 12 Speed: Standard, exceptional endurance

Attack: Bite +4 to hit, 1d8+2 dmg. Groups of 6-10.

Origin: Wolf derivative. Largest surviving gene-forge variant. Multi-modal communication: ultrasonic, postural, chemical.

Pack Pressure

Each Pack member engaged beyond the first: cumulative -1 to all target checks and saves (max -3). Designed to overwhelm.

Territory Protocol

Outer hull: attack without provocation, endlessly, until intruder exits or dies. Mid-sphere: hold back unless directly threatened.

Chemical Tracking

Once scented, Pack tracks an operator anywhere in the outer hull with certainty. The Travelers have a masking compound. It is not freely given.

The Corvids

Gene-Forged Cognitive Observer - Ship-Wide

HP 4 AC 12 (airborne) / 10 (perched) Speed: Flight only

Attack: None. The Corvids do not attack.

Origin: Corvid derivative. ~90cm wingspan. Cognitive architecture expanded beyond baseline, then developed further across two centuries.

Observation Network

Groups of 3-5 at observation points throughout the ship. They track operator movement and communicate what they observe to the other variants. The Pack and Stalkers know where operators are before operators know they are being tracked.

Hostile Response

Attacking a Corvid is an act of extraordinary poor judgment. Captain Reeves ends any negotiation immediately. The Pack begins treating the responsible operator as prey within 24 hours regardless of zone.

Threshold Behavior

Corvids occasionally respond to specific operators as individuals: returning across visits, leaving objects (manufactured and organic) at locations where that person has been. The Travelers find it significant.

Breach Clock

Track Aberrant territorial response as operators push into contested or sovereign zones.

Clock	State	Behavior
1	Territorial	Aberrants hold boundaries. Corvids observe. No incursion into mid-sphere beyond normal probe patterns.
2	Alert	Corvid observation frequency doubles. Pack patrols extend to zone boundary. Stalker pairs reposition to intercept corridors.
3	Agitated	Pack probes into mid-sphere. Stalker activity near Engineering increases. Bioluminescent markers shift pattern in outer hull.
4	Pressured	Pack holds corridor junctions in mid-sphere. Stalkers hunt actively in contested zones. Traveler patrols double.
5	Breach	Aberrants push past zone boundary in coordinated movement. Inner core perimeter under pressure. Corvids go silent.
6	Full Surge	All variants active across all zones. The Travelers seal the inner core. Anyone outside is on their own.

Clock Triggers Advance the clock when: operators enter outer hull without Traveler escort (+1), operators attack any Aberrant variant (+1, +2 for Corvids), faction operatives breach the ship unauthorized (+1), reactor disturbance detected (+2). Reduce: Traveler-mediated withdrawal (-1), 48 hours of no incursion (-1).

GM Only // The Nature of the Aberrants The Breeding Annex was not a colonization tool. It was a weapons program. The pre-Upheaval consortium that funded the Traveler did not intend to seed an alien biosphere. They intended to deliver a gene-forge payload to a rival power's orbital infrastructure. The Mentors knew. Their deaths in the third week were not an accident -- the auto-seal delay was programmed. The children were not supposed to survive either. The ship was supposed to return on automatic pilot with the Annex contents intact and the human witnesses removed. The navigation error that created the Long Loop saved them. The Aberrants that escaped containment in year eighty are not failed colonization stock. They are military-grade biological weapons that have been evolving without constraint for two centuries. The Corvids' cognitive architecture was not an accident of gene-forge drift. It was a design specification. They were built to coordinate the other variants. They are still doing it. What has changed is what they are coordinating toward.

GM Only // What Is in the Sealed Decks The maintenance corridor in the outer hull that has been sealed from the Aberrant side contains the original Breeding Annex control interface. The system is still active. Someone -- or something -- has been using it. The gene-forge production lines have not been idle for a hundred and twenty years. They have been running on a modified program. New variants are being produced. The Travelers do not know this. The Corvids do. The objects they leave at the Arboretum threshold are components from the control interface. Wren Callo-Finn is right about the Corvids' cognitive capacity. She is wrong about their intentions. They are not communicating with humans. They are recruiting.

GM Only // The Ship Is Changing The organic residue on the outer hull walls is not a byproduct of Aberrant habitation. It is a biological integration layer. The Aberrants -- directed by the Corvids through two centuries of incremental modification -- are merging with the ship's physical structure. The GravPot plates in Zone One do not respond to human input because they are no longer mechanical systems. They are hybrid bio-mechanical organs. The hull creaks that do not correspond to structural members are the ship breathing. In another fifty years, the distinction between the Traveler and its Aberrant population will not be meaningful. The ship is becoming an organism. Whether the Travelers remain inside it as inhabitants, symbiotes, or something else is the question no one has thought to ask.

Maintenance log, unsigned, found wedged behind a reactor cooling pipe on Deck G. Handwriting analysis places it at approximately year 140 of the voyage.

"Checked the sub-deck seals again. All holding. But the readings are wrong. The containment systems are drawing power I cannot account for. The gene-forge lines should be dormant. The power draw says they are not. I sealed my report in the maintenance archive and told no one. If I am wrong, there is no harm. If I am right, telling someone means admitting what is down there is not sleeping. It is working."

-- Anonymous maintenance log, ~year 140

Recovered from the Adams navigation workspace during a Traveler cataloguing expedition. Written on ship-fabric in a child's handwriting, dated by context to approximately year 3 of the voyage.

"The adults are gone. Kenji says we have to run the ship now. I do not know how to run a ship. Kenji does not know either but he says we will learn. The stars outside are the same as yesterday. I checked. The computer says we are going the right way. I believe the computer because there is nobody else to believe. Today we ate the last of the food the adults prepared. Tomorrow we start cooking for ourselves. I am scared but Kenji says being scared is fine as long as you keep working. I am going to keep working."

05 Contacts & NPCs Characters

Captain Reeves Finn-Adelaide

Fifth-Generation Commanding Officer // Navigation Tradition // Age 31

Direct descendant of Finn Adams. Silver-haired from cryo cycling. Has been fighting Aberrant incursions since age sixteen. She carries the stellar calculation tradition personally. She can run a periapsis corridor by hand. She has done it three times in combat conditions.

She is not hostile to outside parties. She is precise about what she will and will not discuss, and she draws that line before the meeting starts. Cross it and the meeting ends. She does not re-negotiate after a line is crossed.

Can GetCouncil access, navigation tradition knowledge, Aberrant territorial data, the political lay of the ship.

WantsFor the Council to survive the negotiation period without fracturing. She will trade almost anything to keep the isolationist bloc from winning a Council vote.

FearsThat the isolationist bloc is right and outside contact will destroy what the Travelers built.

Current PressureA Council member from the isolationist bloc has begun making private contact with a faction representative. She knows. She has not yet acted. She is watching to see who the contact is for.

Sable Oduya

Traveler Council Pragmatist // Trade Liaison

Can GetShuttle dock scheduling, supervised Library access, Traveler escort assignments, quiet introductions to Captain Reeves.

WantsA trade agreement that gives the Council something concrete to show the isolationist bloc before the next vote.

FearsThat the isolationist bloc discovers she has been talking to operators before she has something to show for it.

Current PressureA faction representative offered her something she has not yet accepted or refused. Running out of time to decide.

Dav Anker

Traveler Engineer // Reactor Maintenance Rotation

Can GetCFR-4 operational history, unofficial Engineering access during low-traffic windows, an unregistered outer hull route bypassing three of four mined corridors.

WantsCalibration tools for pre-Upheaval Cold Fusion diagnostic equipment. The Traveler fabrications are not accurate enough for precision work.

FearsA micro-fracture he found in a secondary hydraulic trunk three months ago that he has not reported. He patched it. Not certain the patch will hold.

Current PressureThe fracture is showing stress markers again.

Wren Callo-Finn

Traveler Arboretum Keeper // Informal Corvid Observer

Can GetInner core access (with advance notice), the most current Corvid behavioral intel on the ship, introductions to inner core residents who have not spoken to outside parties.

WantsDocumentation that the Corvid cognitive architecture is what she believes it is. She has been building a case for twenty years. Needs outside scientific credibility.

FearsThat she is wrong. The possibility that the Corvids are not what she thinks they are is the only thing she cannot face.

Current PressureA Corvid has been leaving manufactured objects at the Arboretum threshold for three weeks. Small ship-component parts, arranged. She has not told anyone.

06 Encounter Tables GM Tools

Outer Hull Encounters (d6)

A Stalker pair in approach formation. One visible. The operator who spots the first one is already being flanked by the second.

A Pack of seven holding a corridor junction. They are not hunting. They are watching. An operator who stops and does not advance for one full minute will find they clear the junction.

Three Corvids perched on maintenance pipe overhead. They track the party's movement, make no sound, and peel off one at a time in different directions.

The Mentor Section debris field, partially visible through a collapsed access panel. A pre-Upheaval sealed case visible among the debris. The corridor approaching it smells of Stalker markers.

A Traveler armed patrol at the zone boundary. Unexpected position, not on any schedule the operators were given. They want to know why operators are this deep.

No encounter. The outer hull is silent. The bioluminescent markers have gone dark in a fifty-meter radius. Something cleared them out. Thirty seconds to decide whether to move before whatever cleared them arrives.

Mid-Sphere Encounters (d6)

A Council representative intercepts the party between the shuttle dock and their destination. She has a request that is off the formal log. It involves something she does not want Captain Reeves to know about yet.

A Pack member, alone and injured, in a maintenance corridor near Engineering. It is watching the party. It does not attack. It has been here for two days and the Travelers have not dealt with it.

A faction operative, already on the ship through means that are not the shuttle dock, who makes contact to propose something that will complicate the party's current arrangement with the Travelers.

Three Corvids at the Library entrance. They have not been seen here before. The Librarian on Deck E is visibly disturbed and will talk to anyone who asks.

A reactor alert: brief automated klaxon followed by an all-clear that comes too fast. Dav Anker is the on-shift engineer. He will not answer direct questions about it but his hands are not steady.

Captain Reeves, unescorted, moving through the mid-sphere at an unusual hour. She does not acknowledge the operators. Fifteen minutes later, a Council member's personal quarters are sealed from the outside.

Corvid Observations (d6)

A single Corvid returns to the same operator across multiple encounters. It leaves a small manufactured object at the operator's last known resting position.

A group of five assembles on the Arboretum dome edge. They face outward, toward Earth. They remain for exactly seventy-two minutes, then disperse.

Corvids observed at the Adams navigation workspace on the outer hull. They return every seventy-two hours. Nobody has followed them to see where they go after.

A Corvid group moves through a corridor ahead of the party, stops at each junction, and waits. It is leading them somewhere. Following leads to a maintenance corridor sealed from the Aberrant side.

Three Corvids perched above a Pack territorial boundary line. The Pack is not crossing it today. The Corvids are the reason.

No Corvids visible anywhere on the ship for six hours. The Travelers notice before the operators do. Wren Callo-Finn goes pale when told.

Rumor Table (d6)

TRUE: The fourth reactor approach corridor is not mined. The Travelers ran out of materials. Three factions know this. One has already sent a scout.

TRUE: Dav Anker found a micro-fracture in a secondary hydraulic trunk. He patched it himself and did not report it. The patch is showing stress markers.

MISLEADING: The Breeding Annex records were partially destroyed in the year-eighty breach. (The records are intact. The Travelers have been saying this for decades to reduce faction pressure.)

TRUE: A Corvid group has been observed at a location on the outer hull that corresponds to the original Adams navigation workspace. They return every seventy-two hours.

TRAP: A faction contact claims a Council member is willing to sell Annex access coordinates for personal extraction. The Council member is working for Captain Reeves. This is a loyalty test.

TRUE: The Traveler Council vote on external trade access is in eleven days. The isolationist bloc has the votes to win unless something changes.

07 Mission Seeds Missions

Dramatic Engine

A quiet extraction in a ship full of things that can hear you breathe. The cutout is not NAF. It is the Cyber Syndicate, selling the same job to two clients simultaneously. The archive is in Aberrant Pack territory and requires transit through the outer hull to reach the correct access terminal. One Traveler Council member already knows the NAF is making this run and wants it to fail.

Objectives

PrimaryExtract the CFR-4 efficiency data from the Engineering archive without Traveler detection.

SecondaryIdentify the second client the Syndicate sold this job to. They are on the ship right now.

Clocks

Detection6-segment. Advances when operators make noise in contested corridors, trigger Corvid observation cascades, or fail to manage the Council member working against them.

Rival Team4-segment. The second extraction team is already aboard. When this fills, they reach the archive first and the data becomes a race.

Leverage Points The Council member opposing the extraction has a family member in a surface enclave who needs extraction. The Syndicate cutout can be pressured through Baroness Volstok if operators have existing Syndicate contacts. Dav Anker's unregistered outer hull route bypasses three of the four mined corridors.

This mission is not about the data. It is about what operators do when they discover the Syndicate sold them out and two extraction teams are converging on the same terminal while the Pack patrols the approach corridor.

Dramatic Engine

Live capture of a Stalker in its own territory with the Pack nearby and the Corvids watching. The equipment the brief specifies is not sufficient. The Travelers know the Menagerie has a contract and have their own people attempting to intercept. The unidentified buyer turns out to be a PRC gene-forge program that wants the Stalker for reproductive purposes, not study.

Objectives

PrimaryCapture one live Stalker specimen. Deliver to Menagerie extraction point.

SecondaryIdentify the buyer. Decide whether the information changes anything.

Clocks

Breach ClockStarts at 2. Operating in the outer hull with capture equipment guarantees Corvid attention. Each failed capture attempt advances by 1.

Traveler Intercept4-segment. The Travelers have their own team hunting the extraction team. When this fills, Traveler operators make contact. This is not a negotiation.

Leverage Points Wren Callo-Finn's Corvid behavioral data could predict Stalker patrol patterns. She will not give it freely. The Menagerie extraction point requires shuttle dock access, which requires Traveler goodwill. The PRC buyer will pay triple if the specimen arrives with Breeding Annex genetic records attached.

This mission is not about catching a Stalker. It is about what the Stalker is for and whether operators care enough about the answer to do something about it.

Dramatic Engine

Three separate parties want the negotiation to fail, for three different reasons. The transit from the Traveler to the GCOA shuttle involves movement through mid-sphere corridors where a staged Aberrant attack can be arranged by someone who knows the ship well enough to open the right doors. One member of the faction delegation is not there to negotiate. They are there to assess whether Captain Finn-Adelaide can be recruited as a faction asset. She will notice. It will end the negotiation if operators do not manage it first.

Objectives

PrimaryKeep Captain Finn-Adelaide alive through three hours of transit and four hours of talks.

SecondaryIdentify which delegation member is running recruitment and neutralize the approach before the Captain notices.

TertiaryDetermine who on the ship opened the doors for the staged Aberrant attack. That person is still aboard.

Clocks

Negotiation Integrity4-segment. Advances when: delegation member makes recruitment move, Aberrant attack disrupts transit, Captain detects manipulation. When full, Captain walks. Negotiation over.

Saboteur6-segment. The person who staged the Aberrant attack is preparing a second move. When this fills, the GCOA station itself becomes compromised.

Leverage Points Sable Oduya knows which Council members have been making unauthorized external contacts. The staged Aberrant attack requires knowledge of mid-sphere security rotations, which narrows the saboteur list to fewer than ten people. The recruiting delegation member has a file on the Captain that contains errors. The errors reveal which faction compiled it.

This mission is not about protecting the Captain. She can protect herself. It is about protecting the negotiation from the people in the room who came to kill it.

Deliberate Blanks

Leave room for the table to make this world theirs.

One maintenance corridor in the outer hull has been sealed from the inside, from the Aberrant side, for reasons no living Traveler can explain.
The Library on Deck E has a section requiring Council clearance. Captain Reeves has not accessed it in three years.
The Pack's territorial boundaries have shifted twice in six months, both times toward the Arboretum. No one has an explanation.
The Corvids at the Adams navigation workspace return every seventy-two hours. No one has followed them back.
One of the six hundred Travelers was born in a way the genetic records do not account for. The Breeding Annex records would explain this. The individual does not know.
