Saja is a real rarity: a member of Kin, for the most part, refers to human wizards - that is, humans with something else in them allowing them to do magic. However, the Kin are really any magical beings with mixed blood. This can be human and Seelie fey, Shadow's Breath and Phoenix, Wulver and Rusalka - absolutely anything. Beings fall into this category if they do not clearly favor... in control.
Saja is part Haetae – shape-shifting lion – and part Fey, and currently rules the magical domain of North and South Korea. He’s possibly allowed to do this because he doesn’t interfere often, except to maintain his position.
When anyone tries to wrest the title from him, he eats them. Other than that, he doesn’t get involved much. No one doubts his power, but influence is another question entirely.
