If a Wolf, Warg or other variety of canine remains in the presence of an Orc raiding party for long enough they begin to change, warping into a creature that, like the Orcs around them require the minute Essences of the Gods that reside in all living things. This hunger is far greater for the Hounds, allowing them to follow the path of those touched by the gods with ease.
