- Industrial prison complex built into a floating landmass.
- Constantly moving from District to District collecting trash as it passes
- High security prison where the prisoners sort the useful trash and incinerate the rest
- When you’re incarcerated there you instantly lose your membership to whichever District you belong to.
- “The Furnace burns you from the face of the world, from all memory.”
- Dark, dingy, dirty, leaving behind a trail of smog across the landscape.
