Sinner

For centuries and whole millennia, souls languish in hell. They are tempered like steel in the crucible of endless slaughter against each other and lesser demons. For such is the will of the Devil himself. For an eternity, they tear... each other apart, only to be sent on to the next cycle of torment moments later. But each new agony, every defeated enemy, each new circle of hell - this is experience. Experience that cannot be gained by an ordinary mortal. Why is the Prince of Pain preparing countless legions of the deceased souls, taught to kill their kind even with bare hands? And most importantly, what mission is he going to impose on one unfortunate sinner, and why has he given him wings?
