Uncanny X-Men (1981) 373-A

Beauty & the Beast Part One

Marrow tries her hand at graphic story telling as she and Peter share a moment at sunrise. The two set out for the day to a museum that has been haunted by a strange apparition. They are frozen by a picture of Peter's homeland but little do they know that they are being watched by the apparition. Marrow controls her bone growth and meets a boy but when she loses control, he freaks out that she is a mutant and rejects her. She returns to Peter and the two are pulled to another dimension by the apparition, Mikhail Romanov. An ancient cult awaits the moment when their living God will return, they have prepared for this moment for centuries and now it is time.
