The party goes west and enters a large, almost entirely empty room with exits to the north and south. An orcish skull is lying in the center of the room. Lenya does not see anything magical about the skull.
The northern tunnel looks like it leads back towards the fungus room.
The southern tunnel goes thirty feet and stops at a stone door.
Raner recognizes the carved stone door as being of obvious dwarven construction. Furthermore, from the markings and style of the door, he thinks a Temple of Moradin is on the other side of the door.
After Kerwyn, Lylamwyn, Rander, and Toriah study the door, they soon figure out how to open it and use Kerwyn's new tools to pick the lock.
Right before the they pull open the door, Kerwyn spots a cunning stone trap attached to the door, which would cause the corridor floor to give way, causing the party to fall to their deaths in a spike filled pit forty feet below. It takes all of Kerywn and Toriah's skills, but they manage to disable the deadly pit trap.
