After 21st Century

Events

 * c. 50,000
 * Alternate timeline: Upon attempting to return to Atlantis, Sheppard is sent 48,000 years into the future due to a solar flare. Atlantis is seemly long abandoned and M35-117's oceans have dried and the planet has become a desert wasteland due to the sun growing to become a red giant. With the help of a Rodney hologram Sheppard is eventually sent back in time so that he can change the events that happened after he was lost.
