Fistandantilus was a black-robed wizard, considered by the other mages as one of the greatest in the history of Krynn. Although human, he used sorcery in order to extend his life. He saved Raistlin Majere's life during his Test, a fact that changed the young mage's life forever.

In Legends, Raistlin goes back in time to a period just before the Cataclysm to learn from Fistandantilus. His true intention was to learn the archmage's power, kill him, and use his new knowledge to open a portal to the Abyss, where he attempted to defeat the dark goddess, Takhisis.
