Wargs are not mere pet wolves, trained to attack on command. They are born of Ullr’s fury, impervious to the rigours of a mountain winter, tougher and sometimes larger than a horse. A single warg can down a giant elk if it catches it unaware, and a pack is a serious danger even to well-armed travellers. You are never free of the warg’s nose. It will track you for days if it deems you a worthy prize. If you are fierce enough, you can steal the pups and harness this fury yourself: but be sure to serve Ullr well, or you’ll be a meal for the beast soon enough.
