Charlie woke up to an alarm going off, not the kind you set to wake up in the morning, but the kind that means there's trouble brewing. With quick movements Charlie grabbed his gear and ran down the hall passing others speaking worriedly. He reached a room at the end of the underground base and stood in line waiting for orders. What he was greeted with was a digital message that had been sent worldwide. "To all people anywhere in the world, we The Pure have something to share with you. From as long as humans can remember we have been imperfect. As the only Pure in this world we plan to fix that. A week from now all humans will be eliminated and we, The Pure, will start the world anew." The sirens shut off as well as all electronics and from above ground there was sounds of screaming...and explosions.
