OOC: Nezrak to the rescue. I assume we picked up all the gems, though I'm not sure how has them. I've got this great image of everyone turning out their pockets.
IC: Nars digs through his beltpouch and pockets for a moment, but does not turn up a moonstone. When someone eventually finds it, Nars will take it an examine the dial one more time. Turning to his companions, he says, "Er, ah, stand back." He will then carefully set the moonstone in the depression, ready to jump back out of the way if it explodes or the ceiling collapses.
