CHULAK
The people of Chulak, Teal'c's homeworld, are Jaffa -- enslaved servants of the Goa'uld. Among the population are also a number of priests who administer other needs, most notably implantation of larval Goa'uld symbiotes into young Jaffa who have come of age.
The Chulak culture has been forcibly maintained at a minimal progressive level under the heel of the occupying Goa'uld, who have thrones of luxury on the world. The general population exists parallel to an archaic period of Earth, with little to no industrialization.
In certain outlying sectors of the populated areas lie pockets of communities who have been outcast from the Chulak hierarchy, but have avoided destruction. These outcasts live in constant fear in impoverished, makeshift villages, and when a Jaffa or other aggressors are near they run in fear. The priests seem to be the only ones who minister to these outcasts.
