One of the most dangerous things in the world is uncertainty. When you don't know where to draw the line, how do you know what rules to follow, and which to break? This is the essence of chaos, of independent movement, or allegiances tenuous at best.
Although String Theory's setting is defined by a show called Heroes, we expect to see a lack of anyone who can really be identified as a 'hero'. New York City is a bomb-ravaged, unlawful place, and the only greater good is survival. Please bear this in mind when you go to create your character and set their moral compass — a lot of people may be tempted to apply for white knights, and over here in String Theory, not everyone can or should be a hero. We're comfortable with morally gray.
