Uncanny X-Men #241

"Inferno, Part the Second: Fan the Flames!"

Madelyne refuses to believe that Mr. Sinister is her creator. Instead she and her pet "Grey" demons attack him, because he is the mastermind behind the Marauders, who stole her baby. But the orphanage is Sinister’s headquarters, he has built in defensive systems, that chain the Goblin Queen and use her own energies against her. She calls to N’astirh for help, but he remains hidden in the shadows.
