PKMN Fan Fic Plot and Characters

Here's info about my Pokemon story:

Ash and Professor Oak were invited to a region named Mekana. A professor, who's name is withheld, wanted them to do a request involving a research expedition he started. When they arrived to the city that the professor is said to be there, they met with a mysterious group of bad guys who attacks people, blurting out statements about a "shattered piece". Ash managed to clear them away, only to see that they dropped an electronic journal, with only one entry in it:

"Find the Ketsuba Plates"

Ash and Oak wondered what those are. When they traveled around for info, they meet a Professor(still thinking of a name). Oak told him that they got the mail, but the professor never recalled sending them a mail, nor does he even know who Ash nor Oak is. Oak and the professor then team up for their own research expedition, while Ash travels on his own to travel around to beat the Gym Leaders of Mekana, along with meeting old allies and rivals. While on his way, he learns bits history behind Mekana and the villains he met earlier

Brock and Serena happened to visit this place and reunites with Ash
