It was actually two rooms, not four.  As the two doors on either side led into each of the same rooms for respective sides.   With nothing found,  Talia would continue heading down the hallway west.  At sixty feet the hallway would once again widen to ten feet in width.    Of which the hallway continues another thirty feet and ends.   With a door straight ahead at the end on the western end right in the middle of the ten foot.<br/><br/>A glowing silver glyph is right smack in the middle of the door.  Each one of you realize that the glyph is magical.   With the radiance of the glow that comes off of it.
