This is Westin, alpha of the Wapiti pack. He was a part of the Keystone pack for pretty much his whole life, one of the pack enforcers. Before the takeover, Westin had a good relationship with both the Amherst brothers, actually considering them both as brothers, and Sam even more so after the alpha married his older sister.
Westin survived the battle for leadership by not even having been there, something that still bothers him until this day. Getting his sister and her two children to safety was more of a priority, and a request of the pack alpha at the time. By the time he had accomplished that task and returned to the pack's home, everything had ended. He managed to bring the scattered members of the Keystone pack who no longer wanted part of the old pack, forming a new, secondary pack within the region.
As far as for lines, I’d really love for him to have a confidant/advisor who is feels he is able to trust. Maybe someone he's involved with, conventional or nonconventional, or possibly even a mate he joined with just prior to the whole pack takeover thing. I'd also love to see his sister and her two kids in the game. Would also be open to other lines if anyone had ideas.
