The layout is simple the door to the room that the rats came out of.  Is the door at the top of the T intersection.  That the party had ignored in going left and right hallways of the intersection.<br/><br/>The room is only a 20x20 room.  Rubble in the room dominates the room.   As the north wall has basically crumbled.   A 5' hallway lays beyond.   The hallway seems go for about 40' and leads to a four way intersection.<br/><br/>Through as Talia checks this out.   Amara is still back with the donkey.<br/><br/>Nothing is found, no traps or anything else.  The only thing noted is the damaged to the wall and along this hallway.  As if the walls had been violently shook.
