Duke Lankral at The Shadow Vault has ordered you to read the Shadow Vault Decree in the presence of Thane Ufrang the Mighty, and then to slay him.
Thane Ufrang the Mighty sits within his hall overlooking the Savage Ledge. I've studied him. The thane is a patient vrykul, with a head for strategy and warfare. He's also shown a penchant for biding his time and not wanting to overplay his hand in the ongoing battle.
I need him dead!
I've written a decree. Stand before the thane and read it aloud.
<The duke arches his eyebrow in amusement.>
It should... unnerve him at the least.
