The worldPokemon and humans have a long history of both competition and cooperation. From the well-known regions of Kanto and Johto to even the most obscure and barren land of Orre, the lives of Pokemon and humans have deeply been intertwined. While the nature of this relationship is quite murky and still undefined, it is inescapable.
Humans and Pokemon share the same land. They will always be forced to interact: to hate, to love, to fight, to compromise, and to coexist. It is up to both trainers and humans to further define this relationship that they share.
Most wild Pokemon bear mistrust and hatred towards humans who have sometimes regarded themselves as "conquerors" with their advanced technology and traitorous Pokemon companions. However, there are some that look longingly at the peace and love that some domesticated Pokemon and humans share.
Most humans have become comfortable with their position as "trainers," often not thinking about the freedom that their Pokemon have lost. After all, wasn't the good life-- the life of a domesticated Pokemon-- the best? However, perhaps there are some trainers who understand that look of longing that shines in their Pokemon's eyes.
Region after region, humans have invaded lands formerly exclusively owned by wild Pokemon and claimed acres upon acres. Lands once free of steel and concrete have now become urban centers. As the amount of untamed lands dwindled, hostility towards humans increased in the remaining lands.
Zatao.
Explorers granted this name to one of the few remaining regions that have not had major human contact. Pokemon have been reported to be especially hostile in this region, thwarting most attempts at settlement. Trainers of every kind have been invited to help with the further exploration of this region... at their own risk.
