The Bloodseer
"Rhaegar was adopted, like his sister Callista, by Salem and her mate, Sorin, towards the end of her reign. Despite having more in common physically with his mother than his adopted siblings, Rhaegar was not deemed fit to rule the Saddle Creek wolves, as he was too young at the time of Salem's passing. Despite his loyalty to his mother, Rhaegar felt immense jealousy towards Callista for her ease in ascending to the throne. Even though he serves as one of the most trusted and skilled warriors under Callista's rule, Rhaegar still holds out hope that weakness will befall the Saddle Creek Pack, and that he will one day be able to take his sister's throne."
