Field record

The world's last major intact freshwater reserve. An independent Southern Compact holds it by being indispensable to both SCA and NAF simultaneously. The Compact's own hydrologists revised viability from 80 years to 40. Three assembly members know. The rest of the government does not.

When the Great Drought hit in 2031, water engineers ran projections on every major freshwater system in the Southern Hemisphere. The Patagonian aquifer complex — fed by Andean glaciers still intact at elevation — came back as the one system viable through the century. That projection was classified. Word got out anyway.

The Southern Compact emerged from two decades of competing pressure: a coalition of city-states from the Rio de la Plata to Tierra del Fuego, held together by the shared recognition that any of them alone would be absorbed inside five years. New Buenos Aires is the capital — rebuilt at elevation above the expanded estuary, confident in a way that post-Upheaval cities generally aren't.

The SCA presses from the north. The Amazonian Metroplex's water inputs depend on the Paraná-Paraguay network with headwaters in Compact-controlled territory. The NAF has invested heavily in Compact infrastructure through Santiago. The Prometheus League has been operating in the deep Patagonian interior for eight years without opposition. And the Compact's own hydrologists have a classified projection showing 40 years of viable reserve, not 80. That number changes every negotiation the Compact is conducting.

An altitude-forged plateau runner has one fog cycle to pull a sealed brine core from a dead extraction shaft, and finds the real proof of what the salt flats are doing was inside her all along.
