Maw of Souls (initially named "Helheim" and then "Helmouth Cliffs") is one of the max-level dungeons introduced with Patch 7.1.5, found in Helmouth Cliffs within central Stormheim on the Broken Isles. Conversely to the Halls of Valor, Helheim contains the souls of the damned or less worthy vrykul. Much of the instance is contained upon the ghost ship of the damned (Naglfar) where players will encounter two Titan keepers who have been warring for thousands of years and face off against the fallen valk'yr queen, Helya.
- The original name was almost certainly named after the region in Norse mythology called Helheim.
