This room is a small, narrow passageway that continues to the north and
slopes sharply downwards.  It will be a difficult climb down.  Carved out of
the black-brown earthen walls along the sides of the passageway are large,
man-sized holes, where the dead were once placed in a religious burial
ceremony.  Any corpses inside the wall have long since decayed.  A small
collection of humanoid bones are scattered about the room, which make a
quiet crunching sound as you step on them.
