The Vanished Wall was the name for the wall that used to surround the great city of Chidell's Old City. By the time of the Third Dragon War, the wall was already considered ancient, and eventually the city outgrew the walls. The city grew up around the wall, and the wall was torn down for construction of new buildings before the first Kingpriest had ever been crowned. By 1 PC, all that was left of the wall could be stepped over by people traveling into the Old City.
