Sekhmet was noted to had one such device in her possession which SG-1 discovered in her abandoned temple. Once there, Samantha Carter determined the machine's nature, and learned that Sekhmet had been freed from her imprisonment, whereupon she intended to rise to power. There were fears that she had already entered into the timeline and made changes, after an alternate future version of Jack O'Neill arrived at Stargate Command and then died from radiation wounds. Despite their investigation, Sekhmet's forces arrived and took the Aten device away to prevent its destruction. (SG1: "Unleashed Ep 1")
