Black is a king who is hated by lots of people, especially Blue. Blue and Black had an extensive rivalry at the academy they both went to and in later life they became sworn enemies. He is very powerful. He is capable of teleporting, though he does it rarely. He also has a huge castle with loads of guards, although the ownership of it has gone between him and Blue recently. He recently managed to get the rebels on his side, though the method is unclear.
Black, is Black.
