Born in 1322, he was the offspring of a human father and demon mother. He was left to be raised with his brother Caderyn by the human parent to become used to the ways of mortals and serve under their mother as they came of age.
He buried his father in 1338, who became one of the early victims of the plague. Caderyn and Vain parted ways for the first time, but always seem to reconnect at some point.

Due to Vain's mixed lineage, his magic is limited. He can with effort create portals, work with fire and earth/ground based magics. His control of the element of fire has saved his life on several occasions, the most notable was a murder attempt by Victor Maudrin.
