First-Light-Weaves-Living-Song

First-Light-Weaves-Living-Song (often simply called Living Song) was a highly influential Isu Lifeshaper and the head of the Lifeworker rate, bearing the title of Librarian. She was married to Shadow-of-Sundered-Star, the second-to-last Didact and the supreme commander of the Ecumene military. During the Long Night, she led the Conservation Measure, which sought to index all species in the galaxy and transport them to the Ark and other conservation facilities before the Flood could reach them or the Halo rings were fired. Frequently clashing with the Master Builder over the morality of the Array, the Librarian died at the end of the war when the rings were activated, willingly stranding herself on Erde-Tyrene - the ancient homeworld of her people - within range of the Halo effect. She was responsible for the creation of humanity, and implanted many of them with unique "Genesongs" to subtly guide their development.
