Aurochs are large migrating mammals, standing over 7 feet tall. There are various breeds, one ranging from the Realm of the Mammoth Lords to Belkzen's southernmost point. Another, less hardy breed, wanders through the Storval Plateau and the Cinderlands of Varisia. These creatures travel in herds, following the grass that quickly crops up in these volatile climates. They travel in this way to protect each other, adult males forming a ring around those less able to defend themselves when threats arise. Aurochs are most often used by people as a source of meat, wool, and leather.
