Credas was a powerful wizard who was the last survivor of the Triurge, a group of three very powerful wizards who assaulted the fortress of the tyrant Bezenvial and overthrew him on the Isles of the Dawn. Years later, he would learn that Bezenvial's twin sons, Maior and Feior, had awoken from the magical sleep into which they had been put, and waited for them to make their moves.
