What was once Krakoa's best trait has become the X-Men's greatest weakness. For mutants all over the Marvel universe, the living island promised a safe haven away from the people who hated and feared them. They would enjoy free shelter, endless supplies of food, and the opportunity to thrive on a tropical island. The Krakoan gates allowed them to visit any location in the solar system and beyond, and all it would take was a few careful steps. Even resurrection wasn't beyond them. Krakoa promised peace and prosperity.
