You wake up in a scientific lab. You see multiple men in hazmat suits, mixing different substances. All of a sudden, you blackout, from an unknown cause.

Twenty years later, you are in your classroom. You are reading about a kind of human named a Shadow. A human who was injected with the “Blood of Jesus” and once they have been injected with it, they are invincible. You are surprised as a Shadow human sounds a lot like you.
