Charles Xavier and Eric Lensherr weren’t always the famous Professor X and Magento. This is their origin story, the origin story of the original X-Men. Set in the 1960s with the Cuban Missile crises at boiling point, the pot of tensions is being stirred further by Sebastian Shaw, a mutant who has been doing the rounds since the 1940s. He believes that mutants are the superior race, and that they must destroy the inferior human race in order to take their rightful place as masters of the earth. Lebensraum and all that.
