Two hundred years ago, five heroes defeated Ragnarok, god of darkness, and banished him to the Abyss. The world moved on. Then Pandora, Ragnarok's loyal servant, begins the work of pulling him back: recruiting monster armies, raising forces, eliminating every hero and general and rival overlord who stands in the way of returning eternal darkness to the world. Umbral Soul inverts the traditional RPG structure—you play the villain, and conquest is the goal. The question is whether you are powerful enough to make the prophecy real.
