IS what Nedrapter saying impossible? I'm really trying to follow this thread but I'm still unclear on a few things you guys are saying. Just as he is/was I need to know what you consider a "level" and "region". Below I'm going to refer to the different areas as "maps".

Lets just say I have no experience with the editor but I want to a Gm map I have called "village center" and place a door on a building that will link it to another gm map I'm using called "tavern floor 1". Where a player would click the door and load into the tavern map by themselves without other players or GM following and be in new area?
This new tavern map would have 2 transitions in it. One on the door to go back to village center and one on the stairs to link to another map called "tavern floor 2" this is possible? are you saying that as long a I have the maps already I just need to learn how to make these transitions in editor to do this or is there more to it.
