Description: Stargate Atlantis follows the present-day adventures of Major John Sheppard and his military team from Earth that along with two dozen other teams explore distant planets in the Pegasus Galaxy. They use an alien device known as a Stargate that was built millions of years ago by an advanced race of people known as the Ancients. The expedition is based in the Lost City of Atlantis on the planet "Lantea". The city was abandoned 10,000 years ago by the Ancients, who were forced to flee after losing a long war to a powerful enemy known as the Wraith.
