Atlantis

A massive city of the Ancients filled with untapped technology, believed to have served as the central nexus for all Ancient activity in the Pegasus Galaxy. Now that humans from Earth have found the lost city, it has become their base of operations in exploring the galaxy. Six angular pylons connect to a central island, which includes the command tower. The entire city is normally powered by three Zero Point Modules, though they have expired. Power is now supplied by numerous Naquadah Generators brought from Earth.

The city itself is capable of space flight, and originally resided on the surface of Earth, on the continent that became Antarctica. Between five and 10 million years ago the Ancients left Earth with the great city, bringing it to a planet in the Pegasus Galaxy. After a war there with the Wraith, the Ancients submerged the city in an ocean and returned to Earth through the Stargate. The city was found thousands of years later by an expedition team from Earth, led by Elizabeth Weir.

Upon their arrival, the city's systems detected the presence of the Earth team and began reactivating lights and power systems as people approached them -- depleting the overall power supply and shrinking the great shield that held back the water of the ocean in which Atlantis was submerged. Automated systems brought the city back to the surface before the shield failed, though this has left Atlantis vulnerable to attack. The city now sits as an island in the middle of an ocean, with a large land mass only 25 minutes travel by Puddle Jumper -- the small ships left behind in Atlantis by the Ancients.

Since Atlantis' Stargate is believed to be the only one capable of connecting to Earth in the Milky Way Galaxy, and to prevent the capture of the city by the Wraith, self destruct codes were given to the officers of the facility. Two personnel are required to administer codes which will overload the Naquadah Generators, and effectively cause a 20 kiloton-equivalent explosion.

The arms of the city, as well as various other locales within, can be accessible via transport chambers. Atlantis includes numerous buildings of various sizes, with the center facility -- the control tower -- containing the Stargate. The city contains a variety of different resources, including:

GATE ROOM Also known as the embarkation room at Stargate Command, Atlantis' gate room is massive, and suited for battalions of departing soldiers or enormous expeditions. A platform in the center holds the Stargate, allowing access from many different sides in the event of a medical emergency or abrupt evacuation by personnel. Stairs lead downward on either side of the gate, and an upward staircase directly in front of the gate leads up to the operations and conference rooms. Small terraces overlook the gate room on either side of the second level, and the ceiling retracts to allow access to and from the Puddle Jumper bay -- allowing the team to take the small Ancient ships through the Stargate.

OPERATIONS CENTER Positioned across and above the Stargate area, the operations area is the control center of the entire Atlantis base. It is equipped with numerous control stations that allow for the monitoring and maintaining of the base. The Ancient's version of a D.H.D. is also in this room, allowing push-button dialing of Stargate addresses. From here personnel can also control the Stargate forcefield, consult the city's database of gate addresses, manage the city's power resources and city-wide communications systems, and more.

V.R. ROOM This room contains a large, three-dimensional holographic interface that allows users to view recorded information. The history of the Ancients, as well as their star maps, can be projected in this room by stepping on a panel in front of a display console, which initiates a preset program. The room's ceiling is perfectly configured for charting the position of Atlantis in the Pegasus Galaxy, as well as the worlds they seeded with human life many millenia ago.

MEDICAL BAY Chief facility for tending to the sick and injured, which is also well-equipped for biological research. The room can accommodate multiple wounded, as well as Dr. Carson Beckett's on-going gene therapy and medical research.

PUDDLE JUMPER BAY Atlantis is equipped with a spacious, circular Puddle Jumper bay, filled with multiple decks of the small crafts. This room is located directly above the gate room. After selecting a Jumper, the pilot moves the ship into the center of the room, where panels on the floor retract into the surrounding walls to allow entrance into the gate room, so that the ship may be piloted through the Stargate. Ship controls can also retract the roof of the Jumper bay, allowing the ships access to the outside of the city.

CONFERENCE ROOM A basic space with a large table, where the team conducts mission briefings and other meetings. The conference room is directly across the gate room from the operations center. A series of multi-panel doors open onto a terrace overlooking the Stargate.

LIVING QUARTERS Atlantis can sustain countless personnel. Since the Ancients themselves were human, accommodations could not have been more perfect for the members of the expedition from Earth. Some quarters hold multiple beds for multiple individuals, including families, to utilize the same room. However other quarters, such as Aiden Ford's, are smaller and suited for a single occupant.

There are also multiple scientific laboratories in Atlantis. Many of these facilities can be found just in the command tower; the city itself is largely unexplored, and it undoubtedly holds numerous Ancient technologies just waiting to be studied and used by the second generation of humankind.
