Helms Deep

Mentioned in Carnival of Fear, Helms Deep is a place where the dwarf performers of Carnival l'Morai hailed from, though it is unknown if this is a location within the domain of L'Morai, an outlander land, or some other place within the Land of Mists.

Naming Similarity to the Lord of the Rings Universe

A dwarven land with virtually the same name (Helm's Deep) is represented in the written works of J.R.R. Tolkien.
