Vraezis, the Enduring

From publisher blurb:

Vraezis, a once-promising human mage born into a remote village with little exposure to the arcane, had his destiny forever altered when a wandering mage recognized his latent magical potential and took him as an apprentice. Under the mentor’s guidance, Vraezis became a promising young mage but harbored an insatiable curiosity about the darker aspects of magic.
