This addon (which is dependent on DBM being installed) will play the Zelda "Secret" sound when Arthas opens up the Bookshelf after killing the boss in Culling of Stratholme. That is all it does.
The closest thing to any updates I have planned are if people volunteer to help me localize it. Also maybe adjusting when the sound plays by a second or so. We'll see.
Enjoy this as much as I will!
