Wolverine guest-stars in the conclusion to a story that's crucial not only to the history of the X-Men, but to its current line-up as well! The year: 1936. The setting: Edinburgh, Scotland. The set-up: Phoenix (Rachel Summers) is in the clutches of one of the X-Men's most deadly foes, the Shadow King! Standing against him: Shadowcat! Kitty's unexpected ally: Wolverine! But even more shocking than meeting Logan a half-century before they actually first meet is the fact that she could prevent the Holocaust... but to do so may mean the destruction of her future world, which is our present!
