Xaos

The Xaos was a chaos beast lurking at Telkoun's Tower in High Thorog in the Silver Marches. It was twice the normal size of a chaos beast.

History
In 1372 DR, the Xaos had recently been released from the stasis sphere by the evil sorcerer Telkoun Adranther in his tower. Telkoun cast the spell charm monster on the beast, gaining control of the creature and ordered it to drive intruders away from his tower.
