Summary:

Welcome to the Arthena Region. Home to pokemon from Kanto, Johto, Hoenn, Sinnoh, and Unova.
Despite the Arthena Region's distinct population of pokemon, it has never hosted a pokemon league, making it a tourist attraction for trainers seeking new pokemon, but due to the mass amount of trainers, the Pokemon League has decided to make one.
The first Arthena League has just been announced, and people couldn't be more excited. Trainers from all over are gathering to partake in this new league, hoping to mark their names in history as the first champion of the Arthena League.
In the small town of Bayloot, a 14-year old has become a trainer wanting the same thing. Will this rookie trainer be able to surpass the experienced trainers from the other regions?
