It was forged by the Huldra Brothers, Sindri, and Brok, who also forged Thor's hammer, Mjölnir, after feeling responsible for the destruction brought about by Thor. As a weapon made to oppose the power of Mjölnir and inspired by the epic size of Jörmungandr, Brok suggests the axe be named Leviathan.[1] According to Sindri when first meeting him, the blade was made for and given to Laufey who passed it on to her husband Kratos, before her death.

The axe has several runes inscribed on the blade that grants it different powers, among them the use of ice, and the ability to recall the weapon from any distance. It also has two slots for Runic Attacks to be placed in, a heavy and light attack for each slot. The Axe Pommel is customizable with pommels found throughout the Realms or bought to Brok and Sindri.
