There is but a thin, almost imperceptible line separating our world from that of the shadows. In that other world darkness reigns, controlled by the terrors known as the Grave Masters. The Grave Masters slip though that line to terrorize our world with their minions of darkness. All pain, all sorrow, all chaos, is caused by them. They bring greed, pride, lust, envy, gluttony, wrath, and sloth to our world. The Seven Deadly Sins. Mankind is enslaved by them. Bit by bit, all that they live for is being destroyed. But for each of the seven shadow kings, there is someone with the powers to defeat them. Mere humans. Or are they? Will the humans be able to conquer the shadows, triumph over darkness? Or will the Grave Masters see to the end of mankind?
