Bhederin were bison, large semi-domesticated or wild herbivorous ungulates of Genabackis that grouped in massive herds of as many as half a million creatures. The bulls were especially large and territorial. They were described as "huge shaggy creatures" with reddish-brown fur and humps. The Rhivi people followed their migrations. Despite hunting the animals, they were able to walk among them and even ride on their backs.
Fully wild bhederin could also be found in the Jhag Odhan in Seven Cities where they were hunted by the Anibar tribe and others. One technique to hunt them in the Jhag Odhan involved running hundreds off a cliff to their deaths. Afterwards, four or five dozen hunters would butcher the carcasses and smoke the meat on racks.
A larger and more solitary breed of bhedrin could be found on Lether where they wintered in the Awl'dan's pocket forests. They were more than twice the size of a Letherii ox and their bulls were ferocious and belligerent.

While traveling through the Jhag Odhan, Karsa Orlong and Samar Dev witnessed the local tribes hunting and butchering bhederin. Karsa tired of eating rabbits and the occasional deer and he decided to hunt a bhederin of his own. When he spotted a small herd, he charged atop Havok, his Jhag horse, hoping to draw out the herd's bull. To Samar Dev's surprise two bulls answered the Teblor's attack. Karsa was able to kill both bulls. As he proceeded to butcher them he drew interest from the Anibar.
