The event involves a dark future brought about by Mister Sinister's corrupt machinations and his experiment in creating a batch of Mutants called Chimeras.
The series' writers would then continue their current story plans after the finale one-shot, Sins of Sinister: Dominion.
[3][4] In the Next Big Thing panel at the New York Comic-Con in October 2022, the X-Men epic is officially announced after months of teases.
[1] Sinister's machinations will create a horrifying timeline that will extend into several other spin-off limited series, each running for three issues.
[1] During the Professing X: An X-Men Panel in the Thought Bubble comic art festival, the writers talked about the upcoming event and showed off the designs of new characters appearing in the dark future including Wagnerine (chimera of Nightcrawler and Wolverine), a new Captain America whose DNA is mixed with those of Mister Sinister, Xible (a future version of Cable merged with the Arakki Xilo), Rasputin from Hickman's Powers of X, Auntie Fortune (chimera of Nightcrawler and Domino) and Ironfire.
For the most part, Kitty reflects on how everything else is settled and everyone is happy except for Exodus who isn't a fan of sharing the resurrection protocols with humans.
[6] Sinister is in his lab after fleeing from his attack on the Quiet Council where he killed Hope, Exodus, Emma, and Xavier.
They throw their fists in the air in solidarity as Cable descends the steps holding his daughter, the rest of the Five silently crying.
It goes over the 3 points to the protocol process: The remaining Five, Cable, the Stepford Cuckoos, Doctor Nemesis, Mimic, and Synch are meeting.
It's a powerful group of mutants consisting of a mix of the Council, the X-Men, Rogue, Wolverine II, and Angel.
As the X-Men descend into the city, Sinister deploys a bunch of Eye-Boy/Cyclops Chimeras firing optic blasts from all over their bodies.
As the Shaw batteries reach a full charge, Sinister boards a jet with a huge red diamond on it while ranting about how Krakoa wasn't made by the X-Men but by him, Xavier, Moira MacTaggert, Magneto, and Apocalypse.
Kate agrees, saying they would have to figure out how to increase the resurrection rate and find a way to harvest everyone's brain patterns.
Xavier suggests that Forge can pick up where Sinister left off regarding the DNA, and Emma says the Cuckoos can handle the extra psychic workload of taking human imprints.
Ben opens up a small briefcase and pulls out what looks like an injection gun with a needle on the end and a green liquid inside.
She says that though the mutants have a mystical method to bring back their own called the Waiting Room, they can no longer resurrect humans.
The Avengers (consisting of Captain America, Captain Marvel, Iron Man, Nighthawk, and Thor), the Fantastic Four (consisting of Mister Fantastic, Invisible Woman, Human Torch, and Thing), and some X-Men (Storm, Jean, Exodus, Cyclops) attack the Orchis Forge and destroy it.
Her participation in the resurrections somehow fixed his meddling so he had to compromise her by killing her, along with a critical mass of other council members to carry out his plans while he was in the Pit.
Precogs learn that Thanos will be attacking Earth again so Hope borrows Domino's power and using a miniaturized Juggernaut (by an application of Micromax) as a bullet, shot through Thanos' forehead via a Forge-crafted temporal canon, leaving his brain matter scattered through two billion years of history.
However, a sole Doombot claiming the mantle of Doctor Doom has been reportedly sighted working with the few remaining Orchis cells.
Considering Reed Richards too dangerous to be left alive, but rather than risk corrupting his mind for himself, Sinister takes comfort in tricking the Thing into accepting a voluntary X-Gene, placing him under his control.
As a sleeper agent, the Thing is able to wait until the right moment to attack the team while they're lost in a cosmic storm in deep space.
The compromised Thing ends up spreading a lethal version of his rocky skin to his teammates while strangling Reed as their ship is lost forever.
With most of the human members of the Avengers compromised, they start going crazy and partake in increasingly extreme and malevolent actions.
This allows Krakoa to make a deal with Muspelhelm that allows Magik to borrow "a certain sword" that she uses to propel Asgard (where Thor has fled) far away from Midgard.
He continues to observe as the crowd move in to attack the well-meaning man who is grabbed by a Wall-Crawler (a hybrid of Nightcrawler and Spider-Man) belonging to the Night Legion and taken away.
During another Quiet Council meeting, Xavier announces that their hold on the world is such that they no longer need to hide their red diamonds.
Actually, Ironfire, used his blood to shield his skull and charges back into the fray as Xavier is brought into the conflict by Beast.
In his bid to launch himself into Dominion, Sinister activates his failsafe and suddenly every Sinisterized mutant burns alive.
Painting herself as a friend to the Quiet Council, she reveals that Sinister's genes are already inside Professor X, Exodus, Hope Summers, and Emma Frost.
