The Uncanny X-Men #231

In "Dressed for Dinner!", Colossus answers a desperate call from his sister, who believes she’s summoned him back from the dead—only to find himself trapped in Limbo, where she’s already entangled in a perilous struggle to protect the New Mutants from the dark forces of S'ym and Baba Yaga. Written by Chris Claremont and brought to life with striking detail by Rick Leonardi, Dan Green, and Glynis Oliver, this 1988 issue blends haunting emotion with supernatural stakes, all wrapped in a cover by Leonardi and Green that captures the eerie elegance of the realm.
