Ability
This weapon can devour all the things that the user wants even its a god, a demon or any beast that has a soul. The thing it devour will come to the deepest place of the Abyss and this was the weapon that sealed the babel towers and turns them to ashes. But this was also the key to open the gates of the Inferno and that was the reason why all the demons want to steal it from the user. This weapon cannot be controlled by any mortals except if it is a Seraphim or a Demon.
