Jaffa warrior and an early member of the Jaffa resistance. Kol'na was to meet with Teal'c at the Chompka Groves to plan against the Goa'uld. Teal'c, believing he was in the presence of allies, told this to Rak'nor and Ma'kar.

Kol'na final fate is unknown, but it is possible Rak'nor tracked him down or turned him in to his god for his treachery.

Kol'na was of the High Cliffs on Chulak, and may have known Shau'nac.


The Serpent's Venom - Teal'c tells of Kol'na, who is eager to meet with Teal'c in the Chompka Groves to discuss plans against their false gods.
