Steinntung

Steinntung is the language spoken by most Dwarves in the Western Deeplands.
It is full of hard consonants and guttural sounds, and those characteristics often spill over into whatever other language a dwarf might speak.

Steinntung Dictionary:
"Myrkálfar" is the Steinntung word for the Sumraki-Ashaī.
"Wechsylbalg" = Nevernost (Tiefling).
