The Nox

O'Neill and the SG-1 team go to a planet, which has creatures called Fenri that possess the power of invisibility. On arrival they discover Apophis, and a Goa'uld hunting party, they are there tracking the Fenri. O'Neill attempts at an ambush, but all members of the SG-1 team are killed.
They are revived, by a peaceful, fairy like people called the Nox. The Nox can make things invisible from the sight of the hunters, and bring back the dead. O'Neill and the team offer to defend the Nox against Apophis, but the little people have their own solution, and this
for now remains their secret.
