Agents of Prophecy
The Alpha is an ancient werewolf, quite possibly from the 1st Age, which was bound and sealed in a prison by supposedly unbreakable silver chains. Unlike normal werewolves, the Alpha appears to be able to assume its were-shape even during the daytime and when not under the full moon. It is unknown if the Alpha can even return to a human shape at this point.
The party encountered the Alpha, who seemed resigned to his fate as a werewolf and a prisoner, and opted to leave it be. He seemed singularly unimpressed with the party’s silver weapons. Shortly after, the Alpha was released for unknown reasons by a Deathless Servant. It was last heard traveling deeper into The Wynt.
