Werewolves may not change as they please. They mate for life with whomever they choose.
The Alphas care for the other werewolves as if they were their own children. If the Alphas are siblings, they have other mates. The male’s mate is the world’s most powerful Healer, while the female’s is the Lieutenant. The Lieutenant assists the Sergeant in his daily duties and the Healer attends the sick.
The Alphas may only be siblings if the previous Alphas had two children, a boy and a girl. If they had a multiple set of the same gender, they must pick the one that shows the most leadership qualities. The role of Alpha is passed through the family, unless they died before they had children, then the Sergeant is the Alpha Male. If the two Alphas were siblings, their mates would have the new titles and be mates. If the Alphas have no children, they may pick the next Alpha before they die. The Alphas, upon appointing, have the ability to transform into the beast whenever they choose.
