Pick · a · Door
A library of connected mysteries — open one and fall.
Every stop uncovers new threads. Follow one and it takes you somewhere connected, rarely where you'd expect. No two people fall the same way.

About this library
Pick a Door is a library of short, true descents. Each chamber is written like a story and grounded like an encyclopedia — every claim has a factual spine of real science and history. The connections between chambers are the point: follow a thread and it carries you somewhere adjacent, then somewhere you didn't know was adjacent.
There is no feed here, and nothing is trying to keep you. When you want to stop, stop — your tunnel will hold its shape until you come back.
