ACU Corridor administrative hub. 400,000 residents. Best-maintained freshwater port between Kinshasa and Mombasa. Sitting directly above the Lumicite deposit. Nobody outside ACU Command's innermost circle knows both of those things simultaneously.
Built at Kalemie because the pre-Upheaval port infrastructure was intact and the lake access was clean. Twenty years later: 400,000 residents drawn to the cleanest water in central Africa, the best-functioning port between Kinshasa and Mombasa, and Obsidian Wardens who are visibly, genuinely keeping it safe.
The Compact is the strongest argument for ACU governance. It is also sitting directly above a Lumicite deposit whose extraction would destabilize the lakebed and poison the freshwater system sustaining 40 million people.
At night, Lake Tanganyika pulses amber from the deep. ACU says bioluminescent algae. The Brotherhood of Shadows researcher embedded here for six months before disappearing said something else. Her contact is still in the city.
