Illyana Rasputin, Colossus' 7-year-old sister is abducted by Belasco, demon lord of Limbo! Though the X-Men rescue her what seems like seconds later, those seconds represent a years-long ordeal for Illyana--one that starts with losing a piece of her soul, and goes downhill fast! The sorceress Ororo and feline warrior Cat -- alternate-reality versions of X-Men Storm and Kitty Pryde -- aid young Illyana against the terrors of Limbo, including Belasco's henchman S'ym and a twisted, perverse version of Nightcrawler. Trained in good and evil magic, Illyana learns to control Limbo's teleporting Stepping Discs, but as the final battle against Belasco arrives, can good triumph over evil when Illyana doesn't know which one she is anymore?
