The High Folly is a dark, blue-green wilderness site crowded by pale forms and unusual natural features. Dense terrain and scattered remains or creatures make the map feel dangerous before a fight begins, while the broken ground prevents a clear straight-line approach.

For a GM, the location works best as a hostile wilderness set-piece. Cover and irregular terrain let threats approach from several directions, and the visually strange environment supports creatures that would feel out of place in an ordinary forest. It can serve as a fey hunting ground, corrupted grove or remote monster-haunted landmark.
