Greyhawk: ToEE Areas of the Week Updated

We've added two more locations to our Greyhawk: ToEE Areas of the Week section. This week, we've documented two areas from the fourth Dungeon of Elemental Evil the East Wing and the Study. Here's a snippet from the latter:
Decorative tapestries flank the fireplace on the east wall. The southern conceals an open doorway leading to a neat closet, in which the clothing of the two clerics is kept hanging to either side. A full-length mirror is mounted on the east closet wall. Four pieces of gold jewelry (each worth 1,000 gp) lie on a small shelf attached to the mirror's left edge. Another identical but empty shelf is at the right edge; if twisted clockwise, it opens the secret door entrance to a corridor to the mages' room.
