Looking at that old black-and-white map of Aethasia, two things jump out at me.
First: "The Sandlands," (at least I think that's what it says), that are over on the left side. I would assume that's what was originally supposed to be Egypt, except on the other side of Aethasia, there's a place that looks to be labeled "Snowmoors". Maybe it could be the Fogworks, but it doesn't really look like that's what's written there.
Second: Why is there a Giant bird in front of the old mount?
