Callisto is a man that is quick to anger, and yet equally quick to calm. With constant threats to his life from the other members of the Eorka royal family, Callisto is constantly in a battle for his very life. When he does fall in love, he falls in love hard and will do anything it takes in order to keep his lover safe. Surprisingly calm and sweet to those he loves and yet bloodthirsty and cold to those he hates, Callisto can be seen as a rabid dog who is ready and willing to bite anyone.
