I thought about alpha predator too, but then look at the house of kings. A king to a fallen would be a kell or archon or possibly prime servitor. You would have to assume they had a more unified form of ruling on their homeworld to differentiate a kell from a king. Otherwise, it would more likely have been the House of Kells. On another note the names do seem to reference the house's behavior. Ii.e. devils are sneeky, kings are planners, wolves seem, with the last DLC, to be more vicious in thd manner of scavengers. So indeed the term wolves might be more of a situational translation. This is further supported by the fact that you translated Low to mean wolf while Lowoo means space.
