Tekk, Cassandra: You've managed to track down a couple of members of the Last Laugh. They're holed up in a guild safe house in the southern end of Cauldron. You see one of them smirk and almost giggle as you enter the safe house. He turns to the wall, flips a switch, and the rest is blinding light.
When the light clears, you find yourself in a medium sized room, roughly twenty feet deep and thirty feet wide, with an odd gear-shaped door in the northern wall. Fifteen cots and fifteen small chests line the walls of the room; a heavy layer of cobwebs and dust lines everything in the room. You can hear muffled conversation and the movement of multiple creatures beyond the gear-shaped door.
Sando: You move towards the half-open door. Propped open with a stone, the gear shaped door is open wide enough for a man-sized creature to slip through. On the door, you can see a gnomish glyph for the letter "A." It's carved nicely in the old style—simple, direct, clean. After a short search, you find two small holes in the floor, facing up and outwards, towards you. Someone trapped this door.
