Quest: The Final Code
ID: 10446

When you complete this quest, a cut scene should happen.

Jenai Starwhisper yells: Rejoice, my friends! <name> has saved us from the looming shadow that threatened our very lives!
Eckert says: We're saved? We're really saved?! YAHOO!
*Aemon Brightsong applauds lightly, smiling.*
Aemon Brightsong: How fortuitous. I believe this calls for some wine.

Then the world object Brightsong Wine (184753) should spawn next to him.
