Upuat kept track of Osiris' great campaign across the universe; noticing that although Osiris claimed to have civilised 660 planets, he only seemed to have reached 640. When Osiris returned to the Throneworld, Upuat observed the victory parade from a balcony with Sutekh. Sutekh showed Merytra to Upuat at this time. (AUDIO: Coming to Dust)
