Aton was a member of Keturah's people.
He was part of the group which captured and held Ronon Dex, Teyla Emmagan and Lt. Colonel John Sheppard. He came close to the cage where Ronon was being held and was grabbed by Ronon, who threatened to kill him if Sheppard and Teyla were not released. He was killed when the Wraith came to claim Ronon.
