Mark of Incite

After routing out some of the agents of our enemies among us, I'm sure you've noticed as well as I that they have a distinct mark about their under garb. The symbol of an eye, and a bird of some sort. Go recover one of these markings, and bring it to the provincial commander up ahead. I'm sure they could use the insight to help rout out the dissenters causing havoc around Lord Grauenberg's Keep up ahead. Accomplish that, and we might manage a rank or two of marshals marching through Heinrich's on horseback. And I'll tell you what: in my experience, that quells a rebellious mob like nothing else.

Enter Dismal Hollow. Find an Incendiary Cultist hidden amongst the buildings, and kill him. Remove his garb, and take it to Adelmar Kaltenbach in the Reikland Observatory.
