The story in short
Kayn was a Noxian child soldier, sent to Ionia to fight a battle nobody expected him to survive. Zed found him there and made him his personal student in the Order of Shadow.
Kayn is extraordinarily gifted, and he knows it. When he took up Rhaast, the living scythe of a Darkin, the weapon began to corrupt him. Now the two fight over control of Kayn's body, while Kayn dreams of one day surpassing Zed himself.
