A sprawling lowland district occupying the footprint of what was once the Calumet industrial corridor, Cindermoor Flats is a patchwork of scorched earth, improvised housing stacks, and skeletal factory frames that never quite finished collapsing. The ground itself is chemically hostile — decades of heavy-metal leaching have left the soil a cracked grey-orange crust that weeps rust-colored water after rainfall. Residents have adapted with elevated walkways, reclaimed polymer decking, and hydroponic rigs suspended above the contaminated ground.

The Flats occupy a kind of administrative dead zone: too toxic for Ferrogate Security to bother patrolling, too poor to attract Axiom or Ringo development contracts. A loose confederation of block captains and mutual-aid collectives keeps basic order, backed by a few well-armed former Carrion Logistics drivers who settled here after contract disputes. Zheng-Dao Bioelectric maintains a single remediation monitoring station at the district's eastern edge — officially for environmental data, unofficially to watch what salvagers are pulling from the old battery burial fields beneath the flats.
