Ursines were named after the bears of Earth. They were large, barrel-chested creatures with thick fur. They had large, powerful paws and sharp claws which could easily rip flesh. They came in both black and brown fur. It was believed that the ones with black fur were more intelligent.
Ursines had a low intelligence and a very bad temper. Ursines also had a sense of honour within their species, and offending one Ursine could lead to violence by others.
