Ariel is Niko's mentor, a smart old woman with enormous powers, a mentor of the circle of thought, a society as old as the time itself, as she explained to Zach...

Dressing in pastel pantsuits with her trademark white hair and pince-nez glasses, she always stands out. Ariel cares about and looks after Niko, the "best pupil I've ever trained." She's a VERY powerful mage, and while she's quite good natured, she's not one to mess with.

Zachary and Ariel had a couple brief scenes together in Ariel but they seemed to become fast friends.
