A teleportation mirror leads to the part of the Lolthan shrine with the "A Sulfur Scented Crypt" quest. The quest is broken, and the door leading to it is locked, without a way to open it due to the broken quest, I believe. It was open in the earlier days of the server. It is impossible to leave the area with the quest if you are unfortunate enough to go through the mirror.
I beg to differ.
Seconding Crim's assertion. There is definitely a way out of the room.
Yar. Two, in fact.
