Home of the Forerunners, a race bred to be protectors of the Multiverse. This world's rapid evolution has resulted in a planet where everyone and everything from trees to animals to bacteria are super-beings, as well as a hyper-accelerated society where everything is a catastrophically significant crisis event, ruled over by the Royal Family of Warworld.
Traumatize by The Anti Monitor's Crisis on Infinite Earth, the Royal Family have interest in the affairs of the multiverse in order to protect their Earth from another crisis.
This earth includes elements from the pre-Flashpoint earth-48 as for elements of pre-COIE earth-6.
By descriptions seem to be thematically similar to the Top Ten Universe and the Inhumans.
