In life, Kai was a 24-year-old knight. He'd fought in the war against the Empire's invasion, and lost his life at the wrong end of a sword. Raised by a necromancer, he now leads a horde of undead under his new master's orders.

He was once warm, kind, friendly, and energetic. Now he's listless, cold, emotionless. Seeing his old friend and love, however has stirred old emotions in Kai's now-empty heart.

He has white hair and pale, translucent skin. Spectral bones can be seen underneath.
