According to Bilrach, the Mahserrat decided to forgo the Rituals that the Chelon-Mah and Mahjarrat were also bound to do. As such, they died naturally or were captured for sacrifices by the other races. While previously thought to be extinct, in the quest Children of Mah, the Mahjarrat Hazeel revealed himself to originally be a Mahserrat. Upon seeing the inevitable destruction of the Mahserrat he decided to separate from the Mahserrat twisting his body by permanently giving him horns.
