Hey Rejuv fans, I'm with another theory which involves the archetype
For those who are new to this I'll remind you
A being appeared and created the pokemon world. That being was called in today's world of pokemon Arceus. Arceus created Vitus and Nymeria. Vitus left Arceus' side an started the dark side and then Nymeria was left on the side of good and light.
Arceus transformed into an item called the "The Archetype" Nymeria used the Archetype as a last resort to end the first pokemon war
After the battle for the Jewel of Life at the Skyview on Eclysia Pyramid Meli
