(Feel free to debate over the name) This is what happened when people went off the rail with the procedural forest post. There is a dense forest that occupies a static amount of land, and is shrouded in a thick fog. Just enough light come through to be able to vaguely see around you There are the ruins of another old town inside the forest that contains chests and crates (similar loot to what is found in the mines). When you venture in a bit, it becomes extremely difficult to find you way around. This is because of the shifting trees and the fog. Every once in a while while you are in the forest, everything goes pitch black, the light from all light sources goes dim, and there is noise all around you that sounds like things getting pulled from the ground, followed by loud shuffling, then the sound of things going back into the ground. Once the light comes back, the placement of trees is totally different. Players then start to realize something about this forest is off… If two players happen to be in the forest at the same time, they cannot see each other, but can hear the distorted, echoing voices of their comrades. Players will be able to enter together and see each other if and only if, they are physically touching when entering (or maybe used some potion or magic). There are constantly noises of small mammals running around (you may occasionally see one), and owls hooting (you may occasionally see one), rustling branches, as well as the wind blowing through the leaves above. There would also be a special step noise in this area, the sound of leaves and sticks crunching. I know I skipped out on the actual mechanics of it and how it would work, feel free to debate those.
Also, just to clarify, when I say “owl” or something like that, i mean a similar creature, gotta have variety.
