The New Mutants' Illyana Rasputin may be lord of Limbo, but how long will that uneasy crown last when Limbo's demon hordes invade New York? As the X-Men battle Sinister's Marauders, Madelyne strikes a pact to become...the Goblin Queen!

The fate of everything hangs in the balance in the fiery epic that changed the course of X-Men history. The match is struck - watch everything burn!
