*edit* You can still get the quest! You go to the Windrunner Spire..I think in the Ghostlands. Kill them till The Lady's Necklace drops. Thats the quest. After you take it to Sylvanas she sings the song. And you get a book of the lyrics. In both languages they are.. English.. "By the Light of the sun. Children of the Blood. Our enemy's are breaking through Children of the Blood. By the light. Failing Children of the Blood O Children of the Blood By the Light of the Sun Failing Chrildren of the Blood They are Breaking through O Chrildren of The Blood By the Light of the Sun The sun." Thalassian. "Anar'Alath, Anar'Alath belore Sin'Dorei. Shindu Fallen Na Sin'Dorei. Anar'Alath Shindu Sin'Dorei Shindu Fallen Na Sin'Dorei Anar'Alath Belore Shindu Sin'Dori Shindu Fallen Na Sin'Dorei Anar'alath Belore. Belore" Sylvanas use to sing this song (in WoW) after a quest..I don't know which quest though and I think they took it out. But its the Blood elve Eversong Woods background with her singing
