Just like the chapel above ground, the altar is made of a simple stone
and has a few religious artifacts scattered across its surface.  There is a
prayer book lying on the altar opened to a page that describes a powerful
incantation that a devoted priest of the religion could learn to use.  You
become very interested at this and try to take the book off the altar, but
it won't budge.
The High Priest of Maradas floats here in deep meditation.
