Niflheim

"Blessed be the fallen land of Niflheim and our great ancestors. Lay power in this food and us. So that our enemies might suffer."

- Prayer by Jordan, Lily, and Sofus Mahkent

Niflheim is a fallen extradimensional realm which is the home of the Frost Giants.

Mahkent Family
At some point, the Frost Giants became residents of Niflheim. Some of them later left to reside on Earth-2, becoming the ancestors of the Mahkent family.
