Room 2 - Wait there's more than just a well?
The passage extending from the well leads North, then cuts West. The walls here are the same rough rock and mud squelches underfoot.
A ladder on the North side of the tunnel leads up to a platform with a door. Curious place for a door, really.
If you lift the latch and stride through
If you carefully search the door
If you kick in the door
If you're intentionally working back to the entrance
