North Wales
One of the most sparsely settled and wildest places on the British Isles, the northern half of Wales was the last place in the UK to feel the touch of humanity. Across all of Northern Wales, there are mountain villages with no electricity and no running water, and even today there are vast tracks of land free of human settlement. In particular, North Wales is home to Snowdonia National Park, eight hundred square miles of mountains, forests, and rivers -- the largest single tract of wilderness in the UK. The park and the surrounding region are named after Mt. Snowdon, (Eryri in Welsh), the highest mountain in Wales. North Wales isn't the kind of wilderness that one might find in Canada or Siberia, but it's as remote a location as one is liable to find the British Isles.
As a result, Northern Wales is overrun by werewolves, with Predator Kings in particular gravitating to the wilderness of Snowdonia as a way to adhere to their ban. The largest and most powerful pack in the area is the Black Mountain, a pack of almost twenty veteran werewolves led by the elder Coat-of-Snow, a monstrous and inhuman figure who is likely the most powerful werewolf in Britain. The Black Mountain does not have it all its own way, as rival Predator Kings and even some Forsaken Packs have the same idea, most significantly the Blaidd Drwg (Welsh for 'Bad Wolf') pack, composed of some very canny, very skilled Hunters in Darkness led by the alpha Eagle's Reach. And of course, plenty of freshly-changed werewolves gravitate to Snowdonia's wilderness, forming short-lived packs of Ghost Wolves that can cause a lot of damage before they self-destruct. All this means that anyone visiting Northern Wales had better be quite careful not to get caught between rival werewolves hell-bent on holy war.
