Satan

[From the manual]

In some faraway place, in a moment lost into oblivion... The forces of evil have seized the universe. The wizards who governed the world are fall into the hands of the satanic power. Only a warrior may put an end to this nightmare, but first he must surpass the boundaries of magic, as the task to destroy the forces of evil belongs only to a wizard.
With magic on your side, prepare to desecrate the walls of the Palace of Clouds, satanic mansion, prison of the divinity, setting of the bloodiest struggle that took place since the beginning of time.
