Arceus

Arceus, the creator of all, resides in a secluded temple, exuding mystery and power. She initiated the comet era to foster unity between humans and Pokémon. Visitors leave her temple with a sense of awe and more questions than answers. After a comet flew by the night sky, a new era arose for Humans and Pokémon. Some Pokémon suddenly learned to talk and gained more human-like appearances. Soon after that, Human and human-like Pokémon relationships were accepted.
