Proof of Demise: Cyanigosa

Objectives
Archmage Lan'dalock in Dalaran wants you to return with the Head of Cyanigosa.

This quest may only be completed on Heroic difficulty.
 * Head of Cyanigosa

Description
We're being invaded! The blue dragonflight has teleported into the Violet Hold and they're planning on breaking out from there into the rest of Dalaran!

There have already been reports of prisoners inadvertently being freed by their actions. It wouldn't surprise me if they're purposefully letting some of them free.

, can you assemble your team quickly and get in there? Cyanigosa is the leader of their invasion force. Bring me her head!

Progress
Come to think of it, why would you ever teleport into a prison to break out of it? It's only the most secure place in the city.

I think the blues must have truly gone insane!

Completion
The danger is over and the rest of the prisoners that had broken free are being imprisoned once more.

Dalaran owes you a debt of gratitude, !

Now I need to go speak with someone about why it was so easy to bypass the city's anti-teleportation protections within the prison?!
