This world was the site of manufacturing centers for Goa'uld starships with everything from Death Glider's to Ha'tak warships being constructed within the orbital shipyards of Soma-Kesh. As such, they proved to be a major source of profit for Heru'ur who often used its shipyards to produce some or even all the fleets of any Goa'uld client. The only times when Heru'ur refused to produce a craft for another was against enemies that he was at war with at the time. The planet itself was not remarkable and it possessed only a few deposits of trinium along with naquadah. As such, much of the resources needed for ship production came from offworld from such planets like Letopolis. The worlds grass plains possessed facilities for Heru'ur's Jaffa and were even used as a residence whenever the System Lord arrived to inspect the shipyards. Whilst primary a shipyard world, Soma-Kesh was also used to test new prototype designs with weapon ranges as well as locations for low altitude flying being present.
After Heru'ur's death, Apophis moved in to claim the planet which forced the denizens of the shipyards to move the facility into hiding. This denied a powerful resource to Apophis when he came to demand the natives to swear allegiance to him and thus made the planet worthless to him. When Apophis was slain, the shipyards were once again moved into orbit around Soma-Kesh where they awaited the return of their true god. However, if the planet was threatened once again by another System Lord, the crews of the shipyards were prepared to move the facilities once more. (RPG: "Living Gods: Stargate System Lords")
