DESCRIPTION:
Aright, this video lets you hear some of the ambient sounds that Undercity has to offer.

At the bell room you can hear the bell ringing, signifying Arthas' return. When moving further inn to the hall, you can hear the People of Lordaeron cheering and welcoming Arthas back home.

Next we enter the throne room itself, and this is what you hear. Enjoy

Medivh: "Yet prisoners they are, my good king"
King Terenas: "What is the meaning of this? Who are you?"
Medivh: "Humanity is in peril. The tides of darkness have come again..."

Arthas: "You no longer have to bear the weight of your crown. I have taken care...of everything.."

King Terenas: "What is this? What are you doing, my son?!"
Arthas: "Succeeding you... Father..."

Arthas: "Let your eyes be closed..."

Arthas: "This kingdom shall fall... And from the ashes shall arise a new order that will shake the very foundations of the world."
