#Dungeon23 Tomb of the Vampire Queen, Level 7, Room 6

 There is a large chamber beyond Room 6.  This room is wide and open, and small flames can be seen leaping from fissures in the floor and walls.  

Embedded in the walls are several uncut rubies. They are worth 1d8x50 gp each but if taken to a gem cutter their value will increase 1d4+1 times.  There are 5d20 such rubies here, but removing them causes 1d4 hp of damage due to heat and flame for each ruby removed.

There is one other chamber to the rear of this one.
