Werewolf

Werewolves are a type of shape-changing monster in Faerûn that are vulnerable to silver or enchanted weapons and can regenerate most wounds. Infected werewolves transform during the full moon involuntarily. Members of their race that are born with the curse can infect others and can control their shifting. Selûne has a group of non-evil werewolves that worship her, though most lycanthropes are drawn towards the worship of Malar.

Alpha Werewolf
An Alpha Werewolf is a rare subspecies of werewolf. These subspecies naturally draw delta and beta werewolves to themselves, often forming a pack. Alpha Werewolves are able to command delta and beta werewolves in there packs to change at will, disregarding the lunar cycles.

Alpha Werewolves are also able to change into a full wolf themselves. This is a means of avoiding detection and being hunted by werewolf hunters or heroes. They are also able to take the bipedal form that is often associated with werewolves.
