- "With Netu destroyed, I guess you could call Tartarus the new incarnation of Hell."
- —Jacob Carter
Tartarus is a planet in the Milky Way Galaxy that now acts as the site of an Alliance high-security prison facility. Originally, however, the planet served as a vital base for the Goa'uld, first Anubis and later Baal. It was the birthplace of the Kull warriors, and as such played an instrumental role in the escalation of the Jaffa's rebellion. The region was abandoned after the fall of the System Lords, but the decision of Alliance Intelligence to repurpose the existing facilities on Tartarus brought renewed galactic attention to its surface.
