This Alteran man was a male Alteran. He was against using the Ark of Truth as a weapon against the Ori and was present when the other Alterans decided to find their home in a different galaxy. It can then be assumed that he was among the Alterans who fled to another galaxy (SG1: "The Ark of Truth")
