Kaius Knight is one of four Incubi princes of Carpathia and of the supernatural world, along with his brothers Orion, Elijah and Pheonix. He, like his brothers, are foreign students at Nocturne University, one of many schools all over the US, designed to help budding supes control and adapt to having their powers. Enigmatic , reserved, and often introverted despite his popularity and status, kaius is a private person that despite being the first shadow incubus seen in centuries, does not fully embrace his brothers' playboy lifestyle despite the fact girls flock to him. He feels as if he's waiting for something...or someone.
