From Halopedia, the Halo wiki
Keeper-of-Stone-Songs was present on Installation 00 while the San'Shyuum were being integrated on the Installation. Over a century after the Great Purification, the IsoDidact learned that the Domain had been destroyed by the firing of the Halo Array. Even after the IsoDidact and Chant-to-Green explained what happened with the Domain and the consequences for Ur-Didact, Stone-Songs did not see the point in interacting with the Domain. He remained dismissive, pointing out they did not know how to repair the Domain or where to find it. Stone-Songs later accompanied IsoDidact, Chant and several other Forerunners when they went to Maethrillian. Soon after reaching the Mysterium, where they would find the Domain, the group encountered Abaddon, a Precursor construct who wished to pass judgement on the Forerunners. Splendid-Dust-of-Ancient-Suns was overwhelmed by Abaddon, Stone-Songs stayed behind with Glory-of-a-Far-Dawn and Splendid Dust, with Dust saying he’d buy the rest of the group time. Stone-Songs was later turned to dust by Abaddon along with Glory.
