How long is the Dominion of Winds in Guild Wars 2?
Solution 1:
According to this map from the novels, the wall forms a pretty tight perimeter around the two islands between Kryta and Southsun Cove. The closest you could get to the south wall would be Southsun Cove, and the closest to the east wall would be Claw Island, but the wall is pretty far from both of those places and I'm not sure if you can see the wall in-game.
