We are the cast-offs, the forgotten, the broken; we are dark, dangerous men haunted by our violent pasts. The Guardian collects us, rehabilitates us, and gives us a new lease on life...if we follow a few, simple rules: Once you're in, there's no going back; never take a life; loyalty to the brotherhood above all. SIN is all I know-it's my whole world. And then I see HER, and everything changes. We share secret scars...
