From the introduction:
The Dark Knight Trilogy, a darker and more realistic approach of the batman mythos. In this world there is no magic, super powers or aliens but there is still a superhero. Bruce Wayne watched as a child as his parents were shot by a mugger and decided to become the hero that his city needed. Fourteen years later he is ready to return to his city after dedicating himself to training in preparation for fighting crime. That city is Gotham. You arrive one month before batman’s first appearance in a city overwhelmed by criminals, the darkest city in America and one that many if not all have given up on. Saving this city is something thought impossible but perhaps there is hope yet. Or you may decide that the rot that infects Gotham needs to be cut away before it threatens the rest of the world. Or maybe you just want to watch the world burn.
