This world is a perfectly normal, average, run-of-the-mill world. It’s exactly what you would expect: there’s some crime and instability, but otherwise, the human race continues to survive. There’s absolutely nothing special about this world at all. Except, there is one exception to the averageness. There lives one man. The one man who keeps this world from becoming anything less than average. This man is the Strongest Man.
