An ancient race of separatist Jaffa
who, five millennia ago, escaped rule of the Goa'uld
). Branded as traitors, they went into the galaxy to search for Kheb
, and ultimately enlightment, in the hopes that their souls would be cleansed. Instead, they found and established the Sodan homeworld (Earth designation P9G-844
For five thousand years the Sodan have thrived, worshiping the Ancients while raiding Goa'uld symbiote transports as necessary to sustain themselves. Circa 1905 (on Earth) Lord Haikon took the seat as leader and overseer of the Sodan and the preservation of their way of life.
Approximately one hundred years after Haikon took power the Sodan homeworld was paid a visit by a Prior who offered enlightenment through worship of the Ori and the guidelines through Origin. Haikon realized that his people had spent thousands of years paying homage to gods who never gave the people anything in return. However, the Ori were apparently willing to share the secrets of enlightenment.
Since this realization Haikon has lead the Sodan public in Prostration toward the Ori, while a small dissident group continue the Sodan way of life and hope to restore it to the majority.
Since their discovery the Sodan have been criticized for knowing about the existence of the Goa'uld but not helping their distant cousins in their oppressors' defeat. Despite the need for strong leadership in the forming Free Jaffa nation the Sodan do not concern themselves with the condition of the rest of the Jaffa race.
