World Eater
The story opens in the Necropolis where Reed and T'Challa show Tony their findings in reverse-engineering the device found with Black Swan, revealing it to be an antiproton sling used to destroy the Earth she jumped from. They tell Tony that they'll need about two more days to finish their own version. Tony shows them what he's been working on, handing them Shi'ar Omnicasters to project themselves to the other side of the Sun where Tony has hired Shi'ar contractors to build a Dyson Sphere.
Meanwhile, Doctor Strange has been researching methods of his own in the Blu'Dakorr, an ancient magical text of incredible dark power. Strange's studies are interrupted, first by Wong bringing him tea and then the signal that another incursion is taking place. Strange tells Wong that he has left Wong the manager of his estate, should something happen to him, and tells him to live every day as if it were his last, as it may very well be.
The Illuminati convene at the Incursion Site which is revealed to be Ellis Island in New York City. They discuss possibilities, with Reed and T'Challa having found a way to channel an Ultimate Nullifier through a vibranium barrel, which would destroy the other Earth's incursion site but also kill the user. Beast proposes using the other world's Infinity Gems to buy themselves more time, and they decide to go to the other Earth. The team decides on four hours to find the gems, and if that isn't accomplished, Doctor Strange will put into motion an "unspeakable thing" that will solve the problem, at great cost.
Their plans are interrupted however, when they see that the Galactus of that Universe has arrived to consume the Earth.
