Tenryū was born in the Pacific Northwest to an ancient pack that had spent many generations in its evergreen forest. His father was the clan's devout Shinshoku, priest, and his mother, its noble Hime, princess. This union produced four beloved sons in their likeness. Over time, their second-born, Tenryū, was groomed to follow in his father's path. He studied their Shinto religion for many seasons, but received a prophetic dream on the night of the autumnal equinox. Knowing there were others outside their land who sought guidance, Tenryū set off with the purpose to find wanting disciples and a new land to call his home.
