Following the reintroduction, Walking-in-Light-of-Falling-Stars accompanied the IsoDidact and a group of other Forerunners to Maethrillian on a mission to repair the Domain and find ships to leave the Milky Way galaxy. When the Precursor construct known as Abaddon shut down their ship, Splendid-Dust-of-Ancient-Suns wanted to leave; Falling-Stars did as well but noted what Abaddon did to the ship. When the IsoDidact left to find the Organon, he ordered Falling-Stars to repair the ship. Falling-Stars later contacted the IsoDidact as the power returned, informing IsoDidact that he would have two ships ready in less than an hour and asking what had happened. Falling-Stars later piloted one of the ships, the Bravado, while Tread-with-Care piloted the other, known as the Impudence.
