Quick A/N: All I can say is that I did not plan on making the main character a Mary Sue. If you believe it comes across this way, please tell me so I can attempt to fix it. I'm only doing my best.
It's been said that darkness is evil, that it is against everything the light stands for. I know not why so many are afraid of the darkness; perhaps it is merely because they do not understand it. There is nothing different about the world at night, save for appearances and what people believe about it. I have become a part of the darkness, as have many of my kind. Few, if any, have seen us at night and lived.
Some people believe we are myths, that we do not exist. Most people choose not to think about us, try not to realize that we are out there, waiting for one person to make a mistake. The few left know we are real, know about us. But they can say nothing.
Then there are the Yu Yan. We are in constant competition with the famed archers. Every time I hear their name mentioned, I feel unrelenting hatred for them. They pride themselves on fame, wanting everyone to know who they are and what they stand for. It is the most unforgivable insult to one of my kind. Our notoriety comes from silence, using skill and darkness to do what we must. We have no need to spread our name with shows of prowess. That would likely involve venturing into the daylight, something we do only if absolutely necessary. The Yu Yan are also strong believers in the war, something else I despise.
Who exactly am I, you ask? Why do I live within darkness, and do what I do?
I am a creature of the darkness, not entirely human for I hold no fear of its power. I draw strength from the darkness and am able to use all of its powers. I kill out of necessity, with the sole purpose of eliminating those who I must eliminate. This I cannot say for the Yu Yan, who kill to show their skills. This is why I am proud to be what I am.
I am a ninja. And I've been sent to kill Prince Zuko.
