During the time of peace however, Memit's friend, Odan-Urr, received a vision of an incoming threat from the Sith Empire, so Memit Nadill, Odan-Urr, and Empress Teta traveled to Coruscant to warn the Republic. However, the Republic and the other Jedi were hesitant to accept Odan-Urr's warning, for the Sith Empire had fallen into the category of legend and myth. However, Empress Teta is not deterred, she returns to her system to prepare her defenses.

Memit Nadill was accompanying Empress Teta when Jori Daragon stole her way into Empress Teta's palace and warned them about what she had seen of the Sith Empire, and the impending attack on the Republic. Believing that the Empress should take this threat seriously, Memit Nadill makes a journey to Coruscant to enlist the help of other Jedi Knights. On Coruscant, Memit meets with Jedi Knights Sonam Ha'ar, Tuknatan, and one other, and together they discuss plans for rallying other Jedi.

However, the Sith attack sooner than anyone expected, and Memit Nadill and the other Jedi had to fight to protect Coruscant. Together Maemit fought along side the other Jedi and Coruscant soldiers against the hoards of Sith warriors. Once the majority of the Sith forces are shown to be illusions, Memit and the other Jedi have a renewed sense of strength, and are victorious against the Sith. During the ensuing celebration, Memit disconnects his lightsaber, hoping he never has to use it in battle again. Afterwards, he travels back to Koros Major to rejoin Odan-Urr and Empress Teta. There he sets his purpose to rebuilding the Empress Teta system to restore it to its former glory as was seen before the previous war.
