Born one of the 3 blessed brothers of the Heruspex of Sirius, he was blessed with the hunter's gift. Extra sharp teeth, heightened smell, and a thick mane that helped camouflaged him and protect him. was always expected to be a great hunter and maybe the next king, and the pressure was intense. When his brother Set left as an adolescent the pressure on him and Khonsusu grew for who would be the next King. Not long before his year birthday he decided what was best for his brother and pack to leave, giving the throne to Khonsusu. In the night he slipped away just as his brother had before him, and only stopped for a moment to look back. Once he turned his back on the caves he called home, he knew he couldn't look back again. For a while he didn't know where to go, wondering aimlessly in a haze until..
He came across a forest thick with mist, wandering aimlessly for who knows how long. Though his skills in hunting were awe-inspiring, he could barely smell anything in the forest. He became lost, and had nearly given up, when a dark wolf with red markings approached him, introducing himself as Alistare. The two talked, Osiris explaining his past and why he was on the territory, and in turn, the dark lead wolf offered him a place to stay in his own, small pack. Osiris agreed, and the two made their way back to the pack's camp, a cave system that blocked out the mists of their territory.
