Wait, what universe are the Mayor/etc from? They are from many years in the future apparently, how?

They are from the Beta kids’ session. They get exiled to Earth, 413 years after the kids start the game then PM and WV go through a teleporter to get to the Trolls’ universe. WV spends three years on the Meteor while PM spends the time tailing Bec Noir who is tailing the Meteor.
