Descent
By the time the reach the large room, Ehdlannis finds he can no longer understand the barking gnoll tongue which Grassus uses. Grassus points East to the tiled portion when they enter, presumably pointing to the teleportation pad, but the party continues south. By the light of the lantern, they do notice that the two dozen gnoll corpses seem to have disapeared.
Heading south, they enter a hallway that stinks. As they progress, they realize why. They enter a 20' by 30' room that is covered in garbage, much of it seems ancient. The top layer is mostly gnoll offal and discarded food remains. Underneath are glimpses of all sorts of pottery shards, bones, scraps of wood, metal, rusting tools...
An open door stands in the SE corner. Peeking through, by lantern light you see a similar room, covered with trash, though not nearly as much. There are also several cots and a closed door.
