Overlord

The overall main antagonist. The cause of all the main character's dark and angst filled backgrounds is because of this person. The Overlord has power over all the dark guilds/clans, and is the cause of them. This character is not yet revealed in the story, nor do the other main characters have any idea of this person's exsistence. No one has ever seen the Overlord before and only a few characters knows of his existence.
