The strange curled hills are home to the blacksmith's forge, through the logic that it should be as far from Treehome as possible. Because... fire and trees don't mix. And fire and trees and an irresponsible head blacksmith definitely don't mix.

Luckily for the entire village, Amber is the secondary blacksmith when xe isn't mining to get materials for the forge, so unintended fires are at a minimum. Not quite at zero, because Peat is a dramatic sort of not-cat who likes to have fun (even if their idea of fun is a bit different than everyone else's), but it's not that bad.
