So like... How do you prep your players for that kind of campaign? I'm just imagining, "OK. War is finally over. The long rivalry between the kingdoms of Blah and Blahh has ended in a wedding. Now that all that lore is out of the way, Tony the Tiger appears from a planar rift..." I guess I'm asking how you managed to keep World A relevant when World B kicks off the game by tearing a hole in reality.
