Móðguðr

In Norse mythology, Móðguðr (Old Norse: [ˈmoːðˌɡuðz̠], "Furious Battler"; also Modgud) refers to the female guardian of the bridge over the river Gjöll ("Noisy"), Gjallarbrú. She allowed the newly dead to use the bridge to cross from one side of the river Gjöll to the other if the soul stated their name and business, and possibly in turn prevented the dead beyond the river from crossing back over Gjöll into the lands of the living.
