Deliver the Scarlet Crusade Documents to Executor Zygand in Brill.
These will need to be taken to my superior, Executor Zygand, in Brill. With this information, we'll be able to deal a decisive blow to the Scarlet Crusade. Your services have been useful here in Deathknell, but I need someone to deliver this to Zygand, and I believe he'll be able to find you more appropriate work.
Take the road north out of Deathknell. Soon after entering Tirisfal proper, you'll hit a crossroads. Take the eastern fork, and keep going east. You'll pass Cold Hearth Manor along the way.
