From the introduction: What is light without dark? How can you know the measure of a man without a proper foe to pit him against? Can there truly be something as inspiring as a Superhero without a being vile enough to be a Supervillain? Is anyone able to handle the power of a Super Man? There are innumerable answers to each of these questions but the world you find yourself in is one that has taken just one approach to each question. A world where there is light and heroism that exists, often in great concentrations, but only by struggling against great darkness can those heroes succeed.
