Marcher
Commonly seen as a rougher and coarser language, Marcher is the tongue of the Duchies of the Marches and the Empire of Malvan (though the Malvanian aristocracy still speaks Nevarine officially), Marcher is often the language of the common folk in the war torn, feudal Human states of the east. While not as many merchants and aristocrats speak Marcher, a speaker can find common ground with workers in the fields and cities with some variations.
