A Perfect World The Black Panther is cataloguing Earths facing incursions through the Bridge, when he is joined by Namor. Black Panther tells him that he has catalogued the deaths of almost forty worlds, but has found one that has survived two incursions in ways different from their own. Black Panther shows Namor Earth-4290001, a world whose heroes were slain in an alien invasion that conquered Earth. Four years later, a group of outcast heroes calling themselves the Great Society banded together and cast out the aliens. They eventually faced the incursions, and vowed to find a way to avert them. Thus far, they had managed to do so without spilling any innocent blood, and were adamant in keeping it so. The Great Society face a blue incursion, and an invasion by the Mapmakers. They repel the invaders, and one of their numbers, the Norn, uses the power of the Black Priests to destroy the other world.
