The war that Magneto and some of his fellow waged between the humans not themselves mutants, and the X-Men—led to a war of powers and wit on the island of Alcatraz where Worthington Labs developed a cure for those mutants wishing to be normal. Additionally, it was here that, ultimately a former member of the X-Men—Jean Grey was killed. Her death and the power she exhibited just before she herself was killed, became the point of divergence for humans and those called Mutants could finally come to peace and accept one another. The war was a costly one for both sides concerned; but it was ultimately, a war that brought both mutants and humans together and eventually brought about peace for both sides.
