SPOILER WARNING: This article contains spoilers for "Uncanny X-Men" #11, in stores now.
With "Uncanny X-Men's" "Apocalypse Wars" storyline settled, writer Cullen Bunn and artist Greg Land are now beginning the next chapter in the lives of Magneto and his band of cutthroat X-Men. The previous storyline ended with the mindless Archangel drone merging with the human Warren Worthington, creating a newly whole iteration of the original X-Man. Previous issues have also seen the team set up in the Savage Land in a base called War Room X. And all the while, seeds of distrust are being sown between the Master of Magnetism and his righthand X-Man, Psylocke.
Two plotlines converge in "Uncanny X-Men" #11, with both dovetailing into the inclusion of the Hellfire Club in this new story. First, "Apocalypse Wars" revealed to Psylocke that Magneto has been secretly deploying Fantomex and Mystique on top secret missions behind his X-Men's backs. Psylocke now has a big reason to not trust Magneto. Second, the X-Man Monet made a grave sacrifice in order to save the Morlocks: she took on the essence of her vampiric brother Emplate, leaving his influence trapped in her mind and her palms altered with Emplate's life-draining mouths. Worried that her teammates will discover her new secret, the Emplate imprint urges Monet to do something that will distract the X-Men -- and that "something" ends up being exposing Magneto's ties to the Hellfire Club.
Monet approaches Psylocke in secret and tips her off, urging Psylocke and Sabretooth to visit the New York Branch of the Hellfire Club in secret. Upon arriving, they meet up with their inside-person at the Club: Monet.
Monet's not the first X-Man to associate with the Hellfire Club. Phoenix was famously inducted into and corrupted by the Club's Inner Circle during the first Hellfire Club storyline in 1980. Since then, Magneto, Storm and Sunspot have all either held or been offered positions within the club, and Psylocke and Archangel have inherited memberships through their wealthy families. Whether or not Monet is a practicing member of the club or has a familial connection remains unclear, but the final page of "Uncanny" #11 establishes that she's at least comfortable in the Hellfire Club.
The Hellfire Club plot will continue in "Uncanny X-Men" #12, which arrives on September 7.
