The Grim Reaper's Scythe is both a part of the Grim Reaper, and a powerful artifact when it was used by the Grim Reaper's former identity, Ereshkigal, to guide Souls to Irkalla. It was found after the Grim Reaper's defeat by the Lich Azumek the Putrid, then after Azumek's defeat it was sealed and protected by the Order of the Silver Circle.

When former disciples of Azumek attempted to steal it to attempt to become the Grim Reaper themselves, the Order moved it to the Impenetrable Citadel, only for it to be stolen by a group of Godborns who used it to reopen the Axis Mundi in Irkalla. It was then left in the care of Nergal.
