Arcadians
The Arcadians are the human-hearted Weres, born as humans and can only become animals and harness their magical powers at puberty. The Arcadians feel that the Katagaria need to be closely monitored and controlled as to prevent them from being emotionless animals capable of killing without reason.
Arcadian soldiers, Sentinals, usually travel in groups of four, and make it their main duty to track and kill Slayers. Only a few Sentinals are born to each patria and they are chosen by the Fates. Sentinals can be recognized by a geometric design covering one side of their face. The design is a birthmark that appears at maturity, though most prefer to use their powers to hide them.
