Misbeth's Mysterious Mystical Mushroom Mporium

Misbeth's Mysterious Mystical Mushroom Mporium is located just at the very northern end of town, right next to the barrier. The building is of a very strange design and build. It is constructed entirely of found materials, such as driftwood, and field rocks that seem to fit just right to interlock and make a sturdy structure without traditional fasteners or building techniques.
Inside, there are baskets scattered about with whatever goodies are ripe and in season. A wild boar trudges through on occasion, with a sledge full of mushrooms, roots, and whatever else he's been able to forage.
A ways behind the shop is sharp, unnatural rise, almost like a plateau, nearly twenty feet high. Three of the four sides are too steep to easily traverse, but the fourth slopes down gently. The top of the plateau is covered in fog, too thick to see through. Occasionally, the trees up there move around. On top of the plateau is a small homestead, with several structures made out of earth and stone. One is a hut, that looks like it was intended for a very large person. Another is a dugout barn, which is inhabited by a small herd of pygmy goats, two, perfectly ordinary sized goats, named Audrey and Bernard, and an awful squawky axebeak.
