Krearieae are large, birds covered in dense, wooly plumage. They are a sacred animal in the Unser culture. Members of the Fromug tribe breed and raise them as livestock, using their dung as a fertilizer and using krearieae feathers as a source of heat. They are also very powerful fliers and can carry objects almost ten times their own weight. When they are fully grown, they can be as large as an elephant.
