Sentinel

For the episode of the same name, see Sentinel (episode)

Sentinel - A position found among the N'Kai millitary, in their intergalactic war with the Space-Spawn. A Sentinel is a member of their race who is posted to a planet, as Nokkar was to Earth, to keep watch there and defend it from the invaders. Sentinels are not permitted to take prisoners, but are presumably (from Nokkar's own experience) allowed to work with the local inhabitants of that planet.
