World of Al'Dravin
The Beast-Rider is a warrior in a barbarian tribe or clan which has a strong affinity for one type of animal. The animal is the totem of the tribe, and the Beast-Rider makes friends very easily with that type of animal and can train it into a riding beast…even if it's a type of animal not normally considered a riding-beast. In his own society, the Beast-Rider is the elite warrior, and he commands a lot of respect among his own kind.
If the animal ever dies, the Beast-Rider can choose another animal of the same type of his companion. The character must seek out another such animal, and may only be satisfied with the healthiest, strongest, greatest examples of this animal, then there must be some kind of binding ritual between beast and man (for example, a physical combat where the human must be able to saddle and ride the animal in spite of its spirited attempts to throw him.
