The party finds themselves in a cylindrical tube, which is covered by a grate. Above, they can hear fighting from the great above. The party members don’t remember anything at this point in time, and are completely unequipped. Eventually, the grate moves, and thick chains move the party up into a bloodspattered arena. Fun. The arena gates open one by one to release some goblins, 3 orcs, and an ogre, in that order.
