Kiron is the son of Borel. Kiron was still a bit too young to take over the leadership of his house when his father was so ignominiously slain by Corwin. Kiron spent some time training to fight Corwin in a fast-time ways before taking up the mantle of leadership. After a few years of dealing with the running of the family, Kiron left to hunt Corwin down.
Kiron has since given up on his quest to revenge himself on Corwin, and has negotiated with Corwin's family to find some other means of settling the debt of honor.
Kiron has been instrumental in keeping Hendrake from going to war with Amber again.
