Quest:Containment

Objectives
Warden Alturas wants you to enter the Violet Hold and put and end to the blue dragon invasion force. You are to report back to him once Cyanigosa is slain.
 * Slain

Description
Here is the prison key.

My men and I will stay here as a last line of defense in the event that you are not able to overcome the assault.

Be sure to speak with Lieutenant Sinclari. She'll provide you with access to the prison's defenses.

Hurry,. There is little time. The few I left inside will not last long without your help. Report back to me once the invasion forces have been successfully dealt with.
 * The Violet Hold Key (provided)

Rewards
You will be able to choose one of these rewards:

Progress
Is it over? Were you able to withstand the assault?

Completion
The crisis is averted, then?

That is good news indeed. I will forward the news on to Rhonin.

Please, accept this with the gratitude of Dalaran.
