You have gone through a door that you weren't meant to go through and have stumbled into an old style adventure game.
You are in a small room decorated in dreadful taste. There is a door behind you that will take you back to where you came from. I'd take it if I were you. There is a mirror on the wall. There is also an open trap door in the middle of the floor. You could go down but it doesn't look too inviting.
This room was last redecorated April 13, 1996.
The plumbing was repaired November 15, 2005
