Yunlayi are big and strong. They are terrific swimmers, and preferentially colonize cold, wet places. they are Human descended, like all the species of All Out Of Time, and are covered in thick curly wool coats, with a layer of subcutaneous fat for further insulation. They are smart and agile. They are scavengers, and like hyenas can digest anything. Yunlayi eat their friends and relatives after they die, in elaborate funeral feasts.
