(McKay leads Weir, Sumner and Sheppard into a room with a glowing hologram of a woman in a white robe.)
Hologram: ... in the hope of spreading new life in a galaxy where there appeared to be none. Soon the new life grew, prospered. Here ...
(As she continues speaking, Weir, Sumner and Sheppard walk over to Beckett, who is standing on a step behind a small podium.)
Beckett: It's a hologram. The recording loops. This is my second time through.
Sumner: What have we missed?
Beckett: Not much.
Hologram: ... exchange knowledge and friendship (above her head a three dimensional holographic map of the galaxy appears). In time, a thousand worlds bore the fruit of life in this form. Then, one day our people stepped foot upon a dark world where a terrible enemy slept. Never before had we encountered beings with powers that rivaled our own. In our over-confidence, we were unprepared and outnumbered. The enemy fed upon defenseless human worlds like a great scourge until finally only Atlantis remained. This city's great shield was powerful enough to withstand their terrible weapons, but here we were besieged for many years. In an effort to save the last of our kind, we submerged our great city into the ocean. The Atlantis Stargate was the one and only link back to Earth from this galaxy, and those who remained used it to return to that world that was once home. There, the last survivors of Atlantis lived out the remainder of their lives. This city was left to slumber, in the hope that our kind would one day return.
(Beckett steps off the podium and the hologram disappears.)
