Emperor
Though I haven't figured out how to re-add the markers naming areas nor how to set up the first set of Civs that are named by the setting, i.e. The Western Empire, The Land of the South Winds, etc. I posted on his thread about it.
You can add the markers in WorldBuilder. Look for one of the options at the top left of the toolbar.
As for the civ names, you can edit that with Notepad. Open up the WBS and look for teh lines like CivName and CivDesc. You can change those to whatever you want.
