Agnos was a planet in the Milky Way galaxy which was home to a Stargate. Visited at some point in its past by the Ancients, several of their buildings—as well as the planet's Stargate—were still standing by the end of the 20th century. These buildings were made of metal, similar to the cities and outposts the Ancients used in the Pegasus galaxy, instead of the stone buildings usually employed by the Ancients in the Milky Way.
The world was governed by a powerful artificial intelligence created by the Ancients to help them in their goal of Ascension. Once they disappeared from this realm of existence, the computer mind would spread itself and control the entire world where it continued its functions for centuries.
At some point after the Tau'ri started sending SG teams to other planets, Agnos was visited by an Asgard with his drone, a female Jaffa wearing Horus Guard armor, and a Human in ballistic armor. While it is unknown what they accomplished while on Agnos, it is known that they later left the planet through the Stargate and headed to Anima Vitrus. (Stargate Worlds)
