Seiquitur

Alien of the species known as Jaffa. The Jaffa each carry an infant symbiote in a belly pouch. This symbiote is the larval stage of a separate, parasitic species, the Goa'uld, who use lifeforms from around the galaxy as host bodies. There is a strong symbiotic relationship between the larva and the Jaffa, because the symbiote guarantees its host long life and immunity to disease. Teal'c, however, has divested himself of his symbiote, and must now depend on the drug tretonin (a distillate of Goa'uld symbiotes) to live. Teal'c (who succeeded his mentor, Bra'tac, as First Prime of the notorious Serpent Guards of Goa'uld system lord Apophis) was forced to leave behind his son Rya'c and his now-deceased wife Drey'auc when he joined SG-1. His goal in life has been to defeat the Goa'uld, and to seek personal redemption for some of his past deeds.
