>>34773680>"According to an ancient document, time, space, and antimatter, or what combined we call the world, shall be born when Arceus stands on the Mystri Stage."I don't think Arceus really needs the Mistri Stage, just as Dialga and Palkia don't need the Spear Pillar to create a new world.
Older documents are more likely to describe future events.
It would not be strange, considering that ancient civilizations were extremely advanced.
And it is very likely that Arceus and Unown are the same thing, avatars of the original spirit.
Or basically the thousand arms of Arceus.
