A blast from the past, set when Magneto was headmaster of Xavier's School! Magneto may once have been the X-Men's fiercest foe - but when Professor X leaves the planet for life-saving treatment, the Master of Magnetism inherits a new title: teacher! The New Mutants suddenly find themselves under his tutelage, but can these young X-Men-in-training learn to take orders from a reforming super villain who's tried to kill them and their predecessors?! There are two sides to every story, and J.M. DeMatteis and Todd Nauck weave a tale that will show how Magneto was right...from a certain point of view. In fact, the mutant known as Irae has taken Magneto's lessons to heart in a way that will upend even his best strategies! Prepare to meet the Sisterhood of Evil Mutants!
