The Nox

S1, E7: Under government pressure to discover superior technologies O'Neill and the team head to a planet Teal'c remembers which has creatures called Fenri that possess the power of invisibility. They arrive to discover a Goa'uld hunting party led by Apophis is already there tracking the Fenri. O'Neill's attempt at an ambush goes horribly wrong and the members of the SG-1 team are killed. They are revived along with Shak'l a Jaffa who was also killed in the battle by the Nox. The Nox are a small peaceful fairy-like people who occupy the planet previously thought to be uninhabited. The Nox can make things invisible - it is they who shield the A'kasha (a flying insect-like creature) from the sight of the hunters - and bring back the dead. But can they stand up to the deadly technology of the Goa'uld once Shak'l reveals their secret and location to Apophis? O'Neill and the team offer to defend the Nox against Apophis but the peaceful little people have their own solution far beyond the understanding of either Goa'ulds or the people of Earth.
