The Atlantis team visits a planet mentioned in the Ancient database: Doranda, fabled to be a world friendly to the Ancients, is now a worlds that appears to have suffered a post-nuclear holocaust. A wrecked Wraith armada orbits the planet. On the surface, an Ancient outpost sits, untouched.
Dr. McKay is not yet able to determine the exact purpose of the base, but it is obvious that it is the only structure that survived. Colonel Sheppard believes it to be a ground equivalent to the Ancient satellite they once found ("The Defiant One"). However, dead bodies liter the corridors of the installation.
Back on Atlantis, McKay convinces Dr. Weir to allow him to return with a team to the base. He and Dr. Zelenka begin to deduce a theory, but they do not wish to spread it to the others yet. Meanwhile, Ronon and Teyla travel to Belka to trade for a special disease-resistant strain of flaxi which would double the output of crops on the mainland. She is prepared to trade Athosian workers for the strain. Hendon's offer is unreasonable and would only turn the Athosian people into slaves. When he gets up to leave, Ronon threatens him with a knife to force his hand. Later, Teyla confronts him about the delicacies of negotiation. When Ronon departs, the Belkan Mattas returns to Teyla and learns that Dex is of Sateda, a world destroyed by the Wraith. "He is not the only survivor," says Mattas, indicating that there is another Satedan refugee in the village. |
