The Bartuk are pretty much exactly what you'd think -- wielders of two-handed weapons, incredibly strong, staunch allies, etc. Historically, these races don't typically work magic, but when they do, the Bartuk use black magic, usually fire-based spells. From the official description: "Bartuks believe in family, honor and the daily spilling of their enemies' blood. If you see a Bartuk warrior on the prairie, sword in hand, his eyes targeting a monstrous shape many times his size, rejoice. You're witnessing the Great Race for whom the word "fear" has no meaning."
