Arcadio, even though he's a werewolf, was adopted by a vampire clan when he was little. So when he showed up at the Illyrios Academy, a lot of vampires were shocked to find out how much he knew about their history.

Since then, he's been working at the academy with his adoptive parents. He's pretty strong and healthy, with good stamina too. Because of that, he works as a security guard there to keep the place safe.
