This John Sheppard was an Organic Asuran (Nanite created humans) created by Niam's faction in order to learn the process of Ascension. He was created along with the other members of his team. He began to suspect something was wrong when an Asuran probe crashed into the city and was destroyed by the Asuran copy of Major Evan Lorne. Later, he was sparring with Ronon Dex and was cut. He went to see Dr. Jennifer Keller but the wound was healed. He discovered he and the rest of his team were infected by nanites. Dr. Rodney McKay discovered a life sign on the city. It turned out to be Dr. Elizabeth Weir. At that time the Asuran version of Keller explained they were created using nanites and that Oberoth had found them. They were given the Core drive and fled in a Puddle Jumper. Sheppard attached
