A group of shamans are trying to banish an immortal witch so she can no longer use her magic to commit dark seeds. Objects like statues are too weak to contain her soul so they must resort to beings of flesh, so they turn to farm animals. However the animals they try to banish her to are too weak and die, sheep, goats, cows and horses. All except one, a steer. After a very lengthy ritual which involves a lot of witch screeching and bellowing, the steer lives and the witch is now bound within its bones. I need help thinking of a good explanation why a steer can contain a witch's soul as opposed to say, a horse for example. Can you help me? FYI - A steer is a young castrated bull.
