The character Ulgan is the legendary Progenitor of the Ulgan Promethean Lineage. There are multiple accounts of Ulgan's origins, with little, if any, evidence to back up any of them. One such account holds that the Ulgan Progenitor was once a mortal man in a Siberian village. Unknown to Ulgan, the ruling element in his being was spirit, and this made him a fitting candidate for certain dark rituals. The Ulgan demiurge, who some Ulgan call Tengri, sought Ulgan out, in the hope of making a spirit-riven slave from him. Tengri sent Ulgan into Twilight, where he was torn apart by the spirits, and then proceeded to rebuild Ulgan's body.
