It was only a matter of time before the story of the Sinnoh region's distant past was told in the Pokémon series. While animated shorts like Hisuian Snow give a glimpse into the Sinnoh region's history, the mainline animation is about to give Ash Ketchum another crash course in dealing with the legendary pokémon.

The English version of Pokémon: The Arceus Chronicles, a new animated special, is going to be available on the internet in September. Originally released in Japan as four episodes of Pokémon Journeys: The Series, The Arceus Chronicles tells the story of how Ash and a number of his companions from over the years unite in Sinnoh for a festival dedicated to celebrating the Hisui region and its pokmon. The Arceus Chronicles will explore the relationships between Arceus and the land it lords over as well as how some villainous humans attempt to harness Arceus' power for themselves.

Ash has experience interacting with many of the legendaries set to appear in the story, which likely borrows a number of plot points from the games it's inspired. The kind of wild energy the franchise needs right now comes from how comfortable the Pokémon series is broaching topics like what the god of pokémon gets up to in its free time.

On September 23rd, he's going to watch Pokémon: The Arceus.
