- Mounts in Arantus are generally unavailable. Horses exist in the world, but they cannot be used as riding horses or war horses. All but a few horses suffer from a chronic, uncurable disease known as Brittle Bones. They are unable to support the weight of a rider, even a small one, without suffering fractured bones. The origin of this disease is rumored to be due to an ancient curse.
- Pack animals (burros, donkeys, mules) are available for hauling packs, but they are not suitable as mounts. Unlike horses, pack animals do not suffer from the Brittle Bones disease.
