In 1996, it came under attack by the Goa'uld Anhur, Warmaster of Ra. Anhur was close to final victory when an urgent message was sent through the Stargate by Ra ordering him to return to Abydos to deal with an uprising among the Tau'ri. Anhur, believing the message to be false, remained on Tuat to complete his mission.
Several of Ra's Jaffa, fleeing Abydos, managed to make it to Tuat where they informed Anhur of their god's fate. Realising that his own inaction had caused the death of his master, Anhur immediately left Tuat, allowing Amuruu to survive. (RPG: "Fantastic Frontiers: Stargate Season One")
