Spirit of Vengeance

The Spirit of Vengeance was, as described by Demon, the vengeful spirit of all Demons across the millennia who drove themselves to pursuit ultimate power, and the countless innocents who lost their lives doing so.

It had imbued its power into Damien's sword, which during a short scuffle against Aran, Shade comments on how unnaturally powerful the sword was.

After Damien's defeat, Evan is engulfed by the Spirit, who takes on the appearance of Mir and convinces Evan to take up the mantle, but is dismissed and driven out. The Demon comes out, heavily injured and details the Spirit's origins and decides that he must destroy the evil spirit, or else history will repeat itself and Damien will never be freed from his agony. The spirit says that destroying him will also destroy his brother, and after some final words, destroys the spirit. He then carries his brother's lifeless body away.
