Atlantis

"Atlantis is all that remains of the greatest race to inhabit the stars."

- Halling

Atlantis, also called the Lost City and the City of the Ancestors, Atlantus in Ancient, is a city-ship built by the Ancients many years ago, approximately the size of Manhattan. The Ancients left our galaxy several million years ago for the Pegasus Galaxy. Once there the Ancients seeded the galaxy and life began to flourish where once there was none.

History
Atlantis was originally situated on Earth on the continent of Antarctica. When the Plague created by the Ori spread through the Milky Way galaxy, Atlantis was launched from it's home, leaving behind a small outpost and a few Ancient individuals, to set course for the Pegasus galaxy where it remains to this day.

When the Wraith began to threaten the Ancients in the Pegasus Galaxy, the Ancient Council decided to sink the city underwater for protection. However, this was only a temporary protective measure until the Wraith arrived at the planet, approximately the same time Doctor Elizabeth Weir accidently was thrown back in time to Atlantis. It was decided, by the Council, to abandon the city and go back to Earth while Weir secretly stayed behind in stasis until Atlantis was reactivated in the future. Melia, a member of the Council, left this message for anybody returning from Earth:


 * "In the hope of spreading new life in a galaxy where their appeared to be none. Soon the new life grew, prospered. Here we built a network of Stargates *McKay and others talking over the Hologram* Exchange knowledge and friendship. *Above her head a sort of map appears* in time a thousand worlds bore the fruit of life in this form. Then one day our people stepped foot on 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 weren't prepared 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 offer 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."

Due to Weir's displacement in time, an Ancient by the name of Janus set up a fail-safe mechanism to allow Atlantis to rise from the ocean using its star drive in the future when reactivated. With Janis returned to Earth and Weir in stasis, Atlantis remained frozen, except during Weir's various 3000 year awakenings to rotate the ZPMs, until the Atlantis Expedition from Earth arrived at Atlantis in 2004.

When the Atlantis Expedition arrived, after locating the Antarctic Outpost on Earth, they started to explore the city until they Rodney McKay figured out that the city's Zero Point Modules were nearly depleted and that the city's shield would fail, causing a massive flood. After searching Athos for safe refuge due to the inevitable shield failure, the search team eventually brought the Athosians back after a Wraith culling occurred. When the team and refugees returned, the fail-safe mechanism activated and Atlantis rose to the surface just as the shield collapsed. With Atlantis out of the risk of flooding, the Expedition continued to settle down and set up home for the Athosian refugees.

Having learned of the existence of Earth, the Wraith sent three hive ships to attack Atlantis. The Atlantis Expedition was able to destroy the three ships, but the Wraith sent another twelve. Seeing no way of destroying them, the Expedition used a cloak and a timed nuclear warhead to make it appear that the city had been destroyed. The Wraith fell for the ruse, causing them to fall into Civil War, but the secret of Atlantis is now a top priority for the Expedition members.

In 2006, live Ancients were discovered in the void between Pegasus and the Milky Way, who subsequently reclaimed the city and forced the expedition out. Shortly afterwards, the Asurans attacked the city, killing the Ancients and taking Jack O'Neill and Richard Woolsey hostage. John Sheppard, Elizabeth Weir, Rodney McKay, Carson Beckett, Teyla Emmagan, and Ronon Dex launched a daring rescue mission, using the shield generators to emit a massive Replicator disruptor wave. The Expedition was allowed back into Atlantis, keeping one of the ZPMs and sending the other two back to Earth to help with the battle against the Ori.

After a massive attack on Asuras, the Asurans launched an attack on Atlantis, using a satellite housing a Stargate to launch a massive energy beam at Atlantis. Unable to evacuate by Stargate, and unable to fully dissipate the beam after submerging the city, the Expedition used the stardrive to leave Lantea, but the city dropped out of hyperspace prematurely and far from the new intended homeworld.

Technology
Atlantis has a great deal of advanced technology in it, like the Stargate, puddle jumpers, drone weapons, stardrive and the important shield. All these technologies have differnent porposes: the Stargate transportes poeple off world to other planets, the drone weapons defend the city, and the shield protects anything inside it.

Structure
The city has many buildings on it. The largest are in the middle and each of its six piers have smaller buildings. The control tower, the largest of the buildings, is located in the very middle of the city, housing the Stargate and jumper bay. The buildings are not very strong and need the shield to protect them from threats, such as orbital bombardment or a tsunami.
