Stormcloud will tell you that he was guided by Tala to Firestone's new territory, though truth be told he was simply in the right place at the right time. He was always the sort of wolf who enjoyed wandering, and though he now leads a pack beside his alpha, he enjoys greatly his opportunities to scout new areas or return to old territories to see what has changed. It is a mutually fortunate situation he finds himself in, and with his first two cubs watched carefully by other pack members, he finds his restless heart has finally found peace.
He can take charge if and when needed, and while not a solitary wolf by any means, doesn't shy away from being on his own. That his alpha tolerates his... dallyances... away from the pack is a small blessing, but one he is grateful for.
