Aurochs are large migrating mammals, standing over 7 feet tall[1]. There are various breeds, one ranging from the Realm of the Mammoth Lords to Belkzen's southernmost point.[2] Another, less hardy breed, wanders through the Storval Plateau and the Cinderlands of Varisia.

These creatures travel in herds,[1] following the grass that quickly crops up in these volatile climates.[3] They travel in this way to protect each other, adult males forming a ring around those less able to defend themselves when threats arise.[1]

Aurochs are most often used by people as a source of meat, wool, and leather.[2]
