Talk to the Special Forces Officer to learn of the Nobility's spy.
Eliminate the spy!
I have another little task for you! My Scouts have reported that a spy for one of those blasted noblemen has taken up a position there. He is observing the entire area and is supposed to have a box of carrier pigeons with him. I'm afraid that as soon as we march out of here he's going to send a message to Thylysium, and then you can guess what will happen. No sooner has the pigeon flapped its wings than we'll have the entire armed force of the high nobility on our backs. Go and eliminate this person!
Head West from the ruins until you reach a track heading north. Follow the path that branches off to the west – it leads up and round to the top of a small hill.
Talk to the Spy camped at the top and then kill him.
How in the world did you find me? Oh it doesn't matter anyway. Nobody will care once the crows have made short work of your remains. DIE!
Return to Special Forces Officer to complete this quest. This ends the quest chain.
Mission Accomplished? Very good! Then our campaign is now well prepared! In the name of the Inquisition I think you.
