The King of The Verse got bored, decided he wants to cause the rest of the universes to collide in order to entertain him.
Ripping apart several universes to make this happen has caused a number of people to be very upset with him, some of his “entertainment” is a tournament of champions, the winners of this tournament are often entered into his employ, not all of them willingly.
Various groups are trying to put the universes back together, others are trying to keep things the way they are, having found that they enjoy the new things that they have found in other worlds.
At least one country has determined that they have found Utopia. Whether theirs is a true utopia or not is to be determined.
