Blank Mind

Delta is a blank. A cold and emotionless human, created to be used by others and treated like nobody, a trained thief and killer, thats all he is. He has never cared to think about who he is or what he was. You don't care about these things when you only have a year to live.

But the past has a way of coming back to you and soon he has questions that need answering. How is a blank created? Why? And who was he before the blank?
