Jesse's World 5th Edition
General: Known mostly as being the home for a variety of strange and alien creatures, the Barrier Peaks are the westernmost chain of mountains surrounding the valley. Stretching from the Devil’s Spine Mountains in the north to the very mouth of the valley in the south, the Barrier Peaks are riddled with ancient dwarven fortresses, deep caverns, and ruins of unknowable origin. One of the most distinctive locations in the Peaks is the dormant volcano called White Plume Mountain by the local settlers. Visible from miles away, White Plume Mountain towers over its neighboring peaks, the white clouds issuing forth from its cratered top and filling the sky the source of the mountain’s name.
Creatures: Though more ‘common’ creatures such as giants, wyverns, and the odd dragon or two call the peaks home, a number of far more alien and strange creatures also lurk within. Monstrous frog-like creatures, floating creatures comprised only of stalks and eyes, and the hulking, misshapen fomorian giant-kin are just a few of the known denizens. It is not unlikely that other strange monstrosities have gone undiscovered over the years. Thankfully, very rarely do any of the creatures ever venture out of the mountains to harass the humanoid inhabitants of the valley.
