Season 1

In a world of magic and monsters, Krylancelo Finrandi and his foster sister Azalea Cait-Sith were once promising students of sorcery, prodigies at the famous Tower of Fangs. But an experiment gone horribly wrong warps Azalea's appearance, trapping her in the form of a dragon. Elders at the Tower—more interested in preserving their reputation rather than their students' lives—drive off the transformed Azalea and cover up the incident. Outraged, Krylancelo strikes out on his own, taking the new name of "Orphen" and vowing to return Azalea to her normal state.
