Nox (Stargate)

The Tok'ra are a race on the fictional television series Stargate SG-1.

The Nox are a peaceful and fairy-like people, capable of reviving the dead and rendering even large objects invisible (in one instance, a Tollan ion cannon for planetary defense). Isolationist and non-interventionist in the extreme, they feel morally obligated to help both sides of an arguement, no matter if one side is thoroughly evil. Case in point, they will equally aid both the Goa'uld and the Tau'ri (Earth humans).
