Kreyvn the Hider

Kreyvn was a Tribal god of the Nandi who was incorporated into the Grand Temple of Westrun. 

Kreyvn was once a mortal tribesman who would not accompany the warriors of his people to war, and instead, remained behind with the women and children. But when their settlement was attacked, Kreyvn abandoned those he was charged to protect, and fled for his life. 

Being chased by dogs, he climbed a hill and fell from its peak, breaking his neck. Not only did Kreyvn die, but in so doing, he disturbed the rest of an Aeniresa of the old world, which woke and finding his body, took it for a possession.

Then Kreyvn was animated once more. The fear he felt in life was thus amplified and given new vigor. In this form the Aeniresa believed it was Kreyvn and lived as him until it had burned through the body and was liberated once more.

He remains as a source of negative inspiration for others -- inhabiting those who act as the original Kreyvn had.
