On the day of the events of the Return, on the 15th of Airtifae, Mother was defeated and, with the power of the Codas, was banished by Bill's Bimbos in their Titan Apparatus. They decided to send her in her slumber to the smaller purple moon of Al'tehrun, Orchuun. Here, she took up a large portion of the interior volume of this celestial body (nearly 40%), and the spines and mountains on her back are slightly visible even from the surface of Al'tehrun as they poked through the surface of the moon.
