If you're a fan of Elves and the Forsaken in Blizzard's World of Warcraft, then you have to watch this video. It tells the tale of Sylvanas Windrunner as she fell to Arthas while defending the Elvish Capital Silvermoon.
This entire scene is played out as The Lament of the Highborne is being run in the background. The song, which is performed in high elven, is a fitting backdrop to the scenes. While its origins are shrouded in mystery, it was used as a tribute to the Elves who died during the War of the Ancients. Later, in the Troll Wars, this song was sung by the elves of Quel'Thalas for those who fell. Now, it is being performed by Sylvanas to apologize for failing her brethren.
So go and watch the video. Enjoy the haunting melody that plays as one of the champions of the High Elves falls before the corruption and evil of the Scourge.
