I dont know about anyone else, but my curiosity has always struck with what is outside of the worlds we explore. For example: whats outside of Pigswick Academy in Wysteria?
I think an event that allowed us to go deep into the unexplored regions of every world would be cool. Each world would have a small 5-6 part quest line, ending with a difficult boss, with levels to match that of the rest of the creatures in that world.
i think that would be an amazing thing, if only they made an update with that in it! hopefully they will, because i really want to see that happen! :P ~Savvanah EmeraldShade
