Godsever

Godsever was a legendary artifact from Hirokir. It was a blade, renowned for its power to cut off a creature from the power of the divine realms. If the blade cuts a blessed creature, a warlock, a priest, or even an Ascended, they become unable to use any of their divine powers. This essentially allows it to slay creatures that are made invincible by divine power.
When Godsever is used to slay such a creature, it steals their power and bestows it upon the wielder of the weapon. One major drawback of this is that often the wielder of the weapon is unable to properly handle the power bestowed upon them, and they go mad, or worse, became Hallowed or Demons. If they are able to handle the power, they can become Ascended, such as in the case of Vaasdai or Vanessa Fang.
Godsever was extremely integral to two major events that happened at the end of the Age of Darkness. The first was the destruction of Ulgard Greenblood. After Emilio Ventura and Kagami Nakamura managed to reconstruct the weapon, they gathered their forces and confronted him. Eventually, Vanessa Fang laid the killing blow upon him, and became an Ascended being of Shadowlight, the Lady of the Mists.
The second major event was the defeat of Zaikerik the Betrayer. Godsever was gifted from Emilio Ventura to Ayla Vanderstone, and she then used it in the final battle against Zaikerik. Instead of slaying him, this allowed her to bind Zaikerik to the Crown of the Dead.
