(W/A) Various (CA) Marc Silvestri The X-Men's world goes up in flames as the most incendiary mutant crossover of all begins! X-Factor, the New Mutants, the newly-minted X-Terminators and even Power Pack all feel the heat as the Machiavellian geneticist Mister Sinister and the demon lord N'astirh set their respective sights on Cyclops' wife, Madelyne Pryor! 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! Collecting POWER PACK (1984) #40 and #42-43, X-FACTOR (1986) #33-36, X-TERMINATORS #1-4, UNCANNY X-MEN (1981) #239-240, and NEW MUTANTS (1983) #71-72.
