Bunker Lore
When the permafrost claimed the surface, engineers drilled deep to tap the roaring geothermal vents, creating a sanctuary of warmth.
The First Beat
The rhythmic thumping of the magma extractors inspired the survivors. What began as survival evolved into eternal nightlife.
Creation of DJ Cinder
Constructed from salvaged mining droid parts and a shattered mirror ball, Cinder was programmed to maintain morale and manage the power distribution (games).

No currency from the old world matters here. Status is measured in rhythm, joy, and the shared experience of the subterranean groove.
