Just point on the map where they are located, like a circle or a star. It seems a basic info but we had several access on this website regarding basic information, as far as I could see by myself. There is always all kinds of situations on this game. For example: sometimes a new player can reach Ank from the desert and probably will be kind of lost since he will reach the city by the gates instead of the boat. The same about cities on Mainland (free accounts will just walk around). Think this as something for newcomers.
Interesting that Kazz and Svargrond do not have a guide. What about Farmine and other cities?
