Lantea

From The Stargate Omnipedia

Lantea.jpg

The home world of Atlantis for many generations. The Ancients submerged the city below the surface of the ocean at the end of the Ancients' devastating war with the Wraith. The war had led to a Wraith assault on the planet -- which was the center of Ancient activity in the Pegasus Galaxy.

Not long after the arrival of the Atlantis expedition from Earth the once abandoned city's power reached critical lows and an automated mechanism rose the city to the surface to prevent its destruction -- though it left the city once again vulnerable to attack from above.

A large portion of the planet's surface is covered in water, and the raised city sat as an island amidst a great ocean. Near the city -- only 25 minutes away by Puddle Jumper -- is a large continent. After it was discovered, the Athosian refugees in Atlantis decided to resettle there, in order to start a new life in relative safety from the Wraith.

Lieutenant Aiden Ford suggested the name "Atlantica" for the planet.

When the Asurans assaulted Atlantis from orbit Dr. Elizabeth Weir made the decision to leave Lantea in search of a new home world. The city eventually resettled on M35-117, leaving Lantea (presumably) uninhabited once again.
