UL is the mysterious god of the Ulgos, who originally were a tribe of people without a god of their own. He is not counted among the traditional seven, and theologians of their religions are ambivalent in their treatment of him. At the end of The Belgariad, it is revealed that he is the father of the seven gods, and omnipresent as well. He is also god of the monstrous beasts rejected by his sons. UL is served by a High Priest, who is always called Gorim. The successive Gorims, although not immortal, live as long as UL requires them to serve. The successor of the Gorim is identified as having violet eyes. Poledra also served UL for many years, and so may be considered his disciple as much as Aldur's.
