Mystique and her Brotherhood start a deadly assault on Muir Isle by releasing an altered form of the Legacy Virus, all in retaliation against the election campaign of Robert Kelly, a seeming mutant-hater. Mystique blows up Moira MacTaggert's laboratory complex, fatally wounding her. Charles goes to the astral plane to meet with her and retrieve information on the cure to the Legacy Virus, but after gathering the information does not want to leave her alone. If not for Jean and Cable talking him down and pulling him back, the professor would have died with his first love, who states she has no regrets.
