I think it'd be interesting to semi-recreate this in Pixelmon. Make Arceus create a pokemon egg, maybe 1 pokemon per Arceus, or maybe 1 Legendary and 1 non-Legendary, or just one of the Creation Trio as is in the event. There could be a new structure, maybe a new cave dungeon, you'd need to seek out. Probably leave out making another Arceus as an option, as it'd be silly and would prevent infinite chains.
