Xemen

Xemen is the enigmatic leader of the Exia Guild, an extremely powerful dark guild comprised of fearsome individuals from all walks of life. By his impeccable charisma and tact, he brought almost all of the dark mages of lesser dark guilds that were under Grimoire Heart and Oracion Seis under his banner following the fall of said guilds. The combination of his charismatic nature and tremendous strength allowed him to form such a powerful force, but at the same time he tactfully kept things under wraps. He is the main antagonist of the ongoing Xemen saga in the storyline, Chronicles of a Mage. While the specifics are not clear, he desires to create a spell that surpasses the imaginations of the feeble masses.

Though his exact origins are unclear, he is an extremely well traveled individual. Not only has he traveled extensively around the continent, but also throughout the world, visiting different continents over his lifetime. By the same token, his knowledge of the world is vast—ranging from different cultures to history and beyond. While his standing in the world is not high in scale, there are certain people among the upper echelons of the Magic Council that had known of the threat he posed long before he made his move; hid the very fact.
