This small room has a huge pentagram right in the middle of it.  On each
of the pentagram points there are different objects and shapes .  There is a
table filled with empty vials and beakers.  This looks to be a room where
powerful wizards would summon creatures from the netherplanes.  There are
burn and scorch marks on the wall and on the floor.
