Objectives
Vaelen the Flayed at The Shadow Vault wants you to free 8 Ebon Blade Prisoners. They can be found in the cages throughout the greater Jotunheim region.
 * Ebon Blade Prisoners set free (8)

Description
Now that I'm back, I'm certain that the baron will want me to recover my men. I can see that we're barely hanging on here. The Lich King's forces are about to break through and we won't be able to hold without my captured death knights.

Can you assist me once more, ?

Go back to Jotunheim and let them out of those cages. Break the damn locks, I don't care what you have to do. The vrykul likely have the keys.

Just get my men free!

Progress
Certainly there are more of my death knights to be loosed from their cages?!

Completion
Thank you,. With the death knights that you freed, we'll be able to hold the line... for now.

It gets the Key
During the quest, Ebon Blade Prisoner may say "It gets the key. It comes here. It opens the lock." which is a reference to by the way the antagonist, Buffalo Bill, speaks to his victims.
