SG-1 had encountered the Nox in season 1's "The Nox", a fairy-like people that wants nothing to do with humanity, viewing them as "young" and having "much to learn". The Nox can live to be hundreds of years old and have a great desire for wisdom and understanding. They are extreme pacifists and never employ violence for any reason, even to defend themselves. Although they outwardly seem to be primitive forest-dwellers, they possess superhuman intelligence and advanced technology beyond that of the Goa'uld, including a floating city. As they have the ability to render themselves and other objects invisible and intangible, as well as the ability to resurrect the dead, they never need to fight. The Nox also appear in "Enigma" and "Pretense".
