Okay so like.... the squiggly thing in the bottom left corner, that's a crappy recreation of the room, there's 2 little 'beam' looking things in the black and you can actually go in it because it's open and what not.
And honestly, did you think I -wasn't- going to draw a map? That's blasphemy your blasphemer!!! =OOO Lookie it's my house and some rain and there's a drunk dude passed out by a trashcan at the bottom.
You're going to want to go to the arrow pointing to "Terra"
