[b]The Thirteen Seekers of Darkness:[/b]

Leo, Kixham, False Hakim and Young Leo, - The collective Xehanort-equivalents who can do everything Xehanort can do, but more powerful, to the point of planet-busting.
Philippa (Element of Borders) - Able to create enclosed spaces where she can alter one rule of reality as she sees fit. She uses this to create zones where gravity is increased or decreased, where humans cannot breathe oxygen, or where certain types of Magic are stronger or weaker. Her main weakness is that if her 'border lines' are broken, her zones are destroyed.
Baron Carlstein (Element of Munny) - Very game-breaking, as he is able to control Munny to form monsters made of it, magically transfer spells and curses through units of Munny, know what anyone who has Munny on him is doing, and of course, break entire economies with a spell. I might actually make him a neutral party this time around so that he does not magically kill the PCs by transferring a Death Spell through their coins.
The False Angel (Element of Dark and Light) - Can control Kingdom Hearts-style Light and Dark powers. Also, the one who ran the Replica Program in this RP Setting.
[Blank Slot] - Originally supposed to be Horus Luprecal, but no longer.
Lavinia (Element of Food) - Can control edible substances like meat, fruits, vegetables, and alcohol, but not living creatures and plants, or food already in a person's stomach or digestive tract. Food, in this case, is defined as 'nonliving but edible substances that provide nourishment when consumed and are not outright poisonous like arsenic'. This power can instantly cause famine to entire countries.
Mr. House (Element of Technology) - Self-explanatory, but cannot control Magitech. Very powerful.
King Herod: Yes, that King Herod (Element of Usurpation) - Can use one spell or technique from each opponent that faces him, which makes him a powerful opponent.
Simo Hayha (Element of Space) - No, he is not the Xigbar-equivalent.
