Planet approximately one day's hyperspace journey from Earth. The settlements are under the authority of the Lucian Alliance, who use the land to grow massive amounts of kassa.
The Goa'uld Baal stole the Stargate on 452, terminating the Alliance's shipping lanes. As a result, two thirds of the kassa on the planet were rendered useless. Overseer Worrel suggested to his superior, Netan, to use the combined efforts of several cargo ships to salvage it in time.
