Planet containing the relics of a long-dead Ancient city. SG-13 visited this world under the command of Colonel Dave Dixon, and during the standard survey was assaulted by a Goa'uld reconnaissance drone that was performing its own survey for Anubis. The device transmitted a communique to the dark lord prior to its destruction.

Shortly after Al'kesh, gliders, and dozens of troops of Jaffa had landed on the world, assaulting the team. SG-13 received backup from SG-1 and other teams, and was successfully extracted from P3X-666 -- but not without major casualties. Dr. Janet Fraiser was killed in the line of duty while saving the life of Senior Airman Simon Wells.
