There is a Desert village that, im going to assume with the world room overhaul many years back, the exits into/out of were removed. The original exit was hidden in the Aurauch some where.
However, I was able to have someone gate to a merchant within and was unable to find any exits - the area was not a quest zone to my knowledge. Just missed in some renovations. So a rainy day fix to add entrance/exit.
Or add trees so Petal can come and go for fruit as she pleases...
