X-Men #7 by writer Jed MacKay, penciler Netho Diaz, inkers Sean Parsons and Livesay, colorists Marte Gracia and Fer Sifuentes-Sujo, and letterer Clayton Cowles shows what happened on the so-called "Iron Night" in which a Sentinel attacked their new home of Merle, Alaska, leading to the founding of the new team and their new headquarters.
This answers some of the lingering questions about the team, but it also reveals a shocking secret about the aftermath of Krakoa that could change everything for the X-Men, and the rest of mutantkind.
