Journey to the Undercity

This is a quest in World of Warcraft. Players fighting certain mobs in the Ghostlands can get a amulet drop that starts a small quest chain. I know the back story of Sylvanas Windrunner from Warcraft III and The Frozen Throne, and evidently the amulet is a long lost gift to Sylvansas from her sister, Alleria. You take the amulet to Sylvanas and the script has her pretending that it's unimportant and tosses it aside, but as soon as you complete the quest, she does an emote:

"Lady Sylvanas Windrunner looks down at the discarded necklace. In her sadness, the lady incants a glamour, which beckons forth Highborne spirits. The chamber resonates with their ancient song about the Sin'dorei...

Then the game starts playing a rather haunting song in the High Elf language while banshee Highborne Lamenters materialize around her, and glowing effects streak around her chamber.

At the end of the song she kneels back down and picks the amulet back up and whispers, "Belore," which is High Elf for "the Sun."

I found it quite touching. 2 hankies

(As always, if you take the time to look, there's bigger fan out there. I found a write up with lyrics (and translation!)
