When Atlantis's deep-space sensors detect the Aurora, an ancient Atlantian warship, at the edge of the galaxy, Sheppard's team wastes no time hitching a ride to it aboard the Daedalus. Upon their arrival, they encounter a Wraith scout ship. They destroy the scout before it can cause trouble — or so they hope. Sheppard leads his team onto the derelict warship, where they discover hundreds of crewmembers frozen in stasis pods. Although technically alive, the Atlantians are thousands of years old, and their aged bodies can't survive the defrosting process. Still, there might be a way to talk to them: McKay discovers that all the pods are linked by an active neural interface, allowing the crew to coexist with each other in a virtual environment.
