Wolves are a pretty spooky bunch, so it's not easy to find them in the wild. But the gods of Asgard have guaranteed that they'll always know where to find Fenrir: chained to a rock on Lyngvi Island in the middle of Lake Amsvartnir. They've imprisoned him there to make sure he doesn't cause trouble for them during Ragnarök. To make your meeting go more smoothly, you might consider bringing some fresh meat. But be careful when you approach him—he may bite.
