Ghost Fences are magical barriers powered by the remains of deceased dunmer, and their spirits, which can be used to protect or seal off an area. The best known one, both in-game in TES 1-5 and among players is the Great Ghost Fence which ran around Red Mountain and kept Dagoth Ur and the Blight contained. Part of the reason it's the best known is that it required so many remains of so many dunmer that the Tribunal Temple all but banned any other form of burial, which made it impossible for clans to create or maintain their own ghost fences.
The versions of the book
Ancestors and the Dunmer found in the Morrowind and Skyrim games has a section on various kinds of Ghost Fence, and then a note at the end explaining that it was written shortly after the Armstice was signed and Morrowind became part of the Empire, and many things are out of date by the time of the games, including the note about clan ghost fences. (The version in ESO is much shorter, presumably an earlier edition, and doesn't mention ghost fences or a few other things that appear in the later edition.
We were
recently told in various interviews and articles that one of the differences between Vvardenfell in TES 3 and in ESO is that the Blight hasn't started and the Great Ghost Fence hasn't been created yet.
Which means the dunmer were still free to bury their dead in tombs and family shrines or to create clan ghost fences.
I often wondered while playing Morrowind what that would look like. How wide-spread were they? Did they go around whole towns or only certain buildings? Were they as tall as the Great Ghost Fence? What were the attitudes towards them - were clans without them jealous of clans with them? Did the clans with them wish everyone else was jealous? Were dunmer ever pressured to leave their remains to a ghost fence even if they didn't want to? And so on.
I'm really hoping we get to not only see examples of the smaller fences but also learn more about them in the expansion and I'm wondering if anyone knows if anything has been said on that topic so far.
