From the introduction: In some form the Soul Swords have managed to return from the Astral Chaos. Once again they've transformed this world into their personal battlefield. People continue to seek out the legendary Soul Edge for the sheer power it confers. Some may be unaware of its underlying evil and others are just wilfully ignorant, believing that they alone have the willpower to master it where others have failed. The cursed blade's influence is far reaching, corrupting people and making them malfested to serve its own dark purposes.
