The Duality of Time by draco
The Duality of Time: The Harvester and the Saphyr. Consumer of the flesh who creeps about picking away pieces little by little with its bladed talons, watching its many prey with it many eyes. Consumer of the mind who flays memories away as it flies by on wings of steel.~~~~~~~~~~~~
It's admitedly a borderline sci-fi, cause at first glance it could also be fantasy. The sci-fi element comes in with the fact that the creatures are biomechs.
