Is it possible to transfer characters to another game world?
Yes, you can transfer characters to another game world.
For a fee you can transfer a character which has not already been transferred within the last 6 months. An express character world transfer allows you to transfer a character which has already been transferred within the last 6 months.
Note, however, that there are several restrictions, e.g. you can only transfer characters to game worlds with the same or more strict PvP rules; characters that should be transferred may not have a red or black skull; or be assigned to an account whose conduct level is orange, red or black. Finally, note that it is generally impossible to transfer characters to or from preview game worlds.
