Gorthol consults the maps that the party made to figure out how to get back to second level where they need to activate the sword. Once he has a path figured out the party travels several days, winding their way through the different levels to reach the desired room. Once there they decide to put the circle in the column to see what happens. When nothing happens they put the sword in the depression in the floor that looks like it fits the greatsword. As soon as the sword is put into the depression the room lights up with rays of light coming from the columns with the geometric shapes aimed toward the greatsword. Just as quickly as it lights up the rays of lights go out. They pick up the greatsword and wrap it in the Cloth of Identification. They learn that not only is it a +1 greatsword but its +2 against undead and +4 against liches.
