Fallout

Vault 15 is a derelict underground shelter originally designed to test social stratification by dividing its inhabitants into rigid class tiers: upper, middle, and lower. The experiment collapsed into chaos as resource disparities and systemic oppression sparked violent uprisings, leading to the vault’s abandonment. Survivors eventually founded the nearby settlement of Shady Sands , repurposing vault technology to sustain their new community. The vault’s decaying structure now houses hostile raiders, feral ghouls, and remnants of its pre-war systems, including a dormant reactor and sealed command center. Explorers face hazards like collapsed tunnels, radiation pockets, and traps left by its former occupants. The site’s legacy highlights the fragility of engineered social orders and the unintended consequences of isolation in a post-apocalyptic world.
