Dazed, you make your way up out of the vault, or was it a bunker? The stairs stretch on for much longer than you remember.
As the sun is just edging at the horizon, you emerge at the door, squinting as the wind whips sand at your face.
You strain for a moment to orient yourself to the way home, and then it hits you with eerie detail. Somehow remembering every step you took to get here, you trace your way back.
When you get there, the front door is unlocked.
