World of Tarvakar
dwarfs do not change as much as other races, so few speak anything but the old tongue. Hill Dwarfs, Sewer Dwarfs, Roamer Dwarfs. Hill Dwarfs speak the most respectable and clear version of gutter dwarvish. they usually speak a human language or a trade tongue. sewer dawrfs are near impossible to understand at best. roamer dwarfs mix in bits of other languages and love to mix the curses of several together.
