The New Mutants #71

Direct

Magik teleports the team to Limbo but finds that she cannot open another portal to earth. The team battles Sy'm and his Limbo Demons who have been infected with the transmode virus. Illyana discovers that it was the demon N'astirh who saved her from S'ym when she was a young child being trained by Belasco. Magik defeats S'ym, transforms into a fiery red Darkchilde and brings the New Mutants to Times Square--along with hordes of demons as they have been betrayed by N'astirh who keeps the portal open so his forces can invade New York!
