Ginnungagap is a World Item under the possession of the Great Tomb of Nazarick.
Tabula Smaragdina gave it to Albedo without permission from the rest of the guild members. Ainz noticed only just before the game was about to end so he let it slip by.
It seems like it can be used to destroy large areas.
It is the most powerful World-Class Item against physical objects, but it is not very useful against individual targets.
It’s weaker than a specialized divine-class item. Still, it’s still quite strong in that it will never be destroyed or damaged.
Its shape can also be transformed into a black bardiche.
- Ginnungagap is a reference to the primordial void in Norse mythology.
