Uhm, sure. What more details do you want? Well, I'll just start with a short recap of the story I had in mind:
As I wrote, the world/this region is mostly unfertile and decaying for a good amount of time now (several decades/centuries at least). So called invasion pkmn (poison & ghost types) are invading the world and wreak havoc. In the last time more than before. So a council has decided to let the Professor of this region in charge with a solution. He sends out 3 young persons out to go on expeditions to solve this mystery.
Along the way the protagonist has to create an oasis in the middle of a dessert, conquer deadly perils in a poisonous swamp and a haunted tower, ask the various inhabitants of the towns what's going on, discover 2 great forces which want to protect the region, and stop Team Nova's fanatic quest to destroy the world.
Is that what you were aiming for or do you want additional information? =)
