Spinning Compass Network

We've got a new door, open from today until May 16. It's going to "Room 13" in Prohibition Era Chicago on Earth, in 1929, and it opens up onto an alleyway. The door looks like a gate more than anything, and there's a note on it. "Knock 4 times. Password is Compass. Tell no one." so I guess I fucked that bit up.

I can't go through since I'm Na'vi right now, so I don't know what's beyond the alleyway.

Does this belong to anyone?
