Berserkers are the largest of the wolves in Ayrea. These brutes have sharp teeth and elongated claws to match their gruff look and sport a heavier, thicker body than their Dire counterparts. They are darker in color compared to the other species in Kells, where a pup born white amongst their ranks is rare. Their coat still only comes in natural variations but, like many other types of wolves, they often adorn themselves with dyes, tattoos, and varying items found around them.

They often live in family clans that are similar to packs and traditionally adopt surnames that pass from generation to generation to distinguish family lines. Unlike dire wolves, they recognize a King to whom all clan leaders bow their heads and a royal line that stretches back generations.
