From Strategy First: The game places players in a fantasy medieval world, where a dimensional portal to the Outer Worlds has opened, and an enemy from the darkness has encroached the world. Led by a demon named Pompolic, the armies of demonic hordes have taken over most of the planet. With mysterious origins, Pompolic's malevolent spiritual being possesses supernatural powers. His desire is to possess the people and turn them into minions of his dark army, as he wields his power through his servants, the Dark Souls.
