A Dark Light

I don't have a name... I don't know who I am; I don't know what I am. I'm not human... I know that much. Instead of bleeding red, I bleed navy blue. Instead of a bare back, I have a pair of wings. Instead of a heart, there is a dark circle, which appears to be a hole, but isn't. I have no family or friends. I'm all alone in a world that if it knew I existed, I would be targeted, tested and tortured.
