History
Deep in the winter grasp of World War II, Erik Lehnsherr and his wife Magda had just escaped from a prison camp, wondering whether it was pointless and that they would die in the cold winter in their thin concentration camp rags. Charles' future son Legion then appeared, having traveled back to the past to kill Erik, who in the future would oppose his father's dream and become the X-Men's worst enemy known as Magneto.
Legion managed to kill Erik, but he then faded from existence because Erik was not alive to help Xavier in Israel decades later, so Gabrielle Haller died before Legion could be born.
The X-Men were vacuumed up by time, leaving both the dead bodies of Bishop and Erik behind on the woodland crater floor with Magda trying to reach out to Erik.[1]
