The walls of these rooms are a fine marble, and the floor a reinforced
alabaster.  This is a safe haven for Ithrilis, but also a staging ground for
the battles which may have to take place.  There are subtle defenses here -
choke points carved into rooms, high ground built into the inner chambers. 
The architects of this place were cognizant of the frequency with which
religious followers fight.
