>>105901327After the O5 were sent back into the past, causing them to merge with their present selves , Nate Grey discovered that he was dying (AGAIN) because of Editorial Mandates , and so tried to make the Planet Earth into his own personal version of Paradise.
Legion came back to fight him , after unerasing everyone’s memories of him ( from the Finale of his own series a few years ago ).
A Majority ( but not the entirety ) of the Extended X-Family ( plus Apocalypse ) who were still Alive and Powered on Earth-616 as of December 2018 , fought XMan and his brainwashed Horsemen of Salvation , who became unbrainwashed and also fought XMan too.
XMan snapped and erased all of the XFolks who fought him from existence , while falling unconscious on a remote beach somewhere.
But he was actually doing his own version of Heroes Reborn + House of M + that Christian Bale sy-fy movie with Gun-Fu, as all of the XFolks got reincarnated in a pocket dimension with an alternate timeline , where Peace on Earth was achieved by making everyone mutants who repressed their sexuality like Vulcans (seriously).
Meanwhile , back on Earth-616, the Flatscans were outraged by what XMan did ( among others , he destroyed all of the world’s Religious centers , based on Bad Advice from Apocalypse of all people ) , so they caused mutant extinction once again , via the usual pogroms + government-mandated devolution using the Cure from Whedon’s Astonishing Xmen run, which Anole secretly gave to the humans ( but Beast found out before they all got warped ) because he was sick and tired of being a Gay incel because he was a mutant lizardboy.
The remaining Xmen,led by a newly-resurrected trio of Scott/James/Jaime are stuck doing a repeat of Mutant Doom and Gloom for the Nth Time, such that BlindFold killed herself out of despair using that classic slashed-wrists-in-the-bathtub, Loa got murdered off-panel and we only saw her corpse in the snow, and Velocidad rapid-aged to near-death.
