The Ancients, also known as the Gate Builders or Anquietas in their language, were those Alterans who left their home galaxy for the Milky Way galaxy and seeded it with life. They are one of the most advanced races known to have existed, having evolved for millions of years prior to the present day and reaching their level of technology long before humanity evolved on Earth. They are best known as the builders of the Stargates, Atlantis, and Destiny. Most of them have Ascended to a higher plane of existence with near infinite knowledge and power. Nilem12 and Primrose are also the last Ancients.
