Jester is a Diviner and ally to Albus Tryndoe, masquerading as a Court Jester and Oracle. They are completely dependent on Albus, who used dark magic to curse them. Consequently, this is also where they get their powers. Due to proximity to Albus, their curse has caused them to lose all of their former personality and independence, twisting their mind into evil. No one knows their true name or backstory other than Albus.
