Day 1.
As we stepped through the curtain of darkness, a strange tinkling course through our bodies. On the otherside Cora lit a torch to illuminate the dark room. It's walls were plain, and it was identical to the room we left behind, withon difference there was a door located on the north side of the room. Out of curiousity, we attempted to re-enter the curtain, and found our way blocked by a magical force. It was as we suspected, no way to return.
In the first hallway we encountered a trio of orcs, who were wounded badly and weak. Out of compassion we gave them some of our rations, and in return they gave us information. It turns out our teachers were not the only ones to enter the celestial prison. Something the orc's called a "rat-man" (A lycanthrope, maybe?) led an army of orcs and the like down here, in search of treasure. Instead they only found death, in the form of somekind of huge insects, and "dark cloaks".
We continued our search, room by room. We learned very quickly the quickly that some of the room are trapped. Some so will designed that they escape the notice of Shall, our rogue. The prison itself is well designed, I think I would like to meet the ones who made this place. After encountering fire, acid and rats, we have decided to call it quits for one day, and continue on tomorrow. There has been no sign of our lost mentors.
