We could have a branching storyline with different dungeons for that story path. (These would be unlockable as "Optional" Dungeons to players who picked another path.) Let's say Rev Toll becomes a city state... Minfillia and the others offer you a permanent stay with them and dealing with certain other primals, or you could continue with other stories concerning the Garlemald Empire, etc. It would be an innovative step in an MMORPG... that's for sure.
