Now aware of the Hellfire Club's existence, the X-Men infiltrate their headquarters, where they are defeated and captured. However, they escape before Shaw can put them to use. Shaw's control of the Hellfire Club grows more tenuous as Pierce proves to be a mutant-hating traitor to the Club and a new recruit to the Inner Circle, Selene, sets her sights on replacing Shaw as the chairman. The Hellfire Club is forced to battle alongside the X-Men against Nimrod, a Sentinel from the future, and though victorious, two key members perish in the fight. After the battle, the Hellfire Club and the X-Men become allies of sorts, with Magneto and Storm filling the position of White King. Arguing that Shaw's support of the Sentinels is endangering the Inner Circle, Magneto, Selene and Emma vote him out of the Club.
