Jupiter is the brother of Whispering Stalk Pack's current leader, Elara. They were born in the same litter, but Jupiter is a month and a half younger than her due to an "Aging Crystal" given to and used by Elara and a witch's spell sometime afterward, reversing her age by half a month. He is quite close with his sister and is very loyal to her.
He has a mate within the pack named Biyoni, whom he adores and thinks is the most beautiful wolf he has ever seen.
