Heroic: The capital was called High Charity and was taken over by the flood. Legendary: John was kidnapped when he was six years old. He was then replaced by a flash clone which later died of... Cancer? I dunno a lot of shit went wrong with those poor clones. Addon: Halsey recruited/"borrowed" John because he was physically and mentally superior to his classmates and his strive to win, AND, his luck. That clone question had me going bonkers man, good god.
