The Great Storm laid waste to the Earth for a generation. The majority of humanity perished. The survivors became roving packs of storm-sick who roamed the landscape in a voracious hunt for food. Human in physiology only, these creatures lived a life of agony, constantly warring with each other and battling the elements to survive.
A few weathered the storm with their minds in tact. Among these were the unnamed survivor and Rio. When the storm finally ended, their story continued in a new chapter of history: the AS (After the Storm) Timeline.
