What If?: Event Horizon #[nn]

Synopsis

It has been years since Vulcan and his team of new X-Men defeated Krakoa and rescued Cyclops, even though the rest of the original X-Men tragically died. Vulcan has become Earth's greatest hero, idolized by millions. That is, until the Silver Surfer brings the remains of Krakoa back to Earth and the X-Men learn that Vulcan killed the original team to cover up the accidental death of Jean Grey by his hand. As punishment, Xavier banishes Vulcan to live on Krakoa to be constantly reminded of his crimes in order to teach him a lesson.
