Fantasy styled Dwarves, and FF styled Dwarves also included here, are just short humans with stout bellies and big beards. They don't have any discernable features of Dwarfism from real life.

If anything, I think their voice lines (if there will be any) will cause more of an unrest with the Scottish audience than with folks with Dwarfism. I've a few Scot friends that absolutely hate and revile how badly Dwarves sound in some MMO's/games/movies.

RALLY HO AND CARRY ON!
