Stargate Atlantis

After the legendary city of Atlantis is found in the distant Pegasus Galaxy, a multinational team travels through the Stargate to explore it. Led by diplomat Dr. Elizabeth Weir and the resourceful Major John Sheppard, the expedition discovers advanced Ancient technology and a vast, deserted metropolis with secrets beneath its halls. Cut off from Earth, they must build a life in their new outpost, forge alliances with local worlds, and defend Atlantis from a ruthless new threat.

A breakthrough reveals the location of Atlantis, the long-lost city built by the Ancients. Stargate Command assembles an international expedition to reach it, placing Dr. Elizabeth Weir in charge of diplomacy and governance while Major John Sheppard leads field operations. When they arrive, the team finds a sprawling city of dormant systems, hidden laboratories, and powerful technology that can change the balance of power across the Pegasus Galaxy. Early discoveries come with steep costs, leaving the expedition isolated from Earth and forced to rely on limited supplies, ingenuity, and each other. As they restore parts of the city and learn how its defenses and transportation network work, they attract attention from nearby civilizations and encounter Teyla Emmagan, a capable leader who becomes a vital ally. Their presence also stirs an ancient predator known as the Wraith, turning exploration into a struggle to protect Atlantis while navigating shifting alliances, internal tensions, and the mysteries of the Ancients.
