Profane Dreams

We had a detailed report of this cult's activity, having spent the night observing them, but those blasted flesh hounds sniffed us out and doom fell upon us. My patrol was cut down in a bloody slaughter. They may be armed with daggers, but when they swarm you they are like those Lustrian fish you hear about in the dockside taverns of Altdorf. One of their leaders is Dieden Bloodmane, he is mainly in charge of gathering fresh blood for the sacrifices. That is what became of my patrol. He deserves death. The report was in Rebekha's boot. I saw them drag her off into their tent while she still lived. Her cries ended before sunrise. If you wish to find the report, it'll be with her.

Find and kill the Khornite ringleader, Dieden Bloodmane. Then search for the Griffon Sacrifice, Rebekha, inside the tent. The scouting report should be on her person.
