Kreghn was a sage of philosophy, who was chosen by Kabraxis to be his prophet in the mortal world. He imparted the concept of the Three Selves to Sanctuary, compiling it in a tome that was banned. Later, other scholars took over from where Kreghn had left off. According to rumor, one of Kreghn's disciples managed to open a portal to Kabraxis during the Mage Clan Wars, but this was never confirmed.[1]
