To Serve Any Master is a war table operation in Dragon Age: Inquisition.
Acquisition
Unlocks upon capturing Caer Bronach Keep in Crestwood.
Operation text
Here's an interesting thing: Among the various things we found at Caer Bronach that belonged to its former mercenary inhabitants was a journal - and in it I found mention of several high-placed clerks in the Imperial Counting House who are, shall we say, known for their loose tongues. They sell what they know to mercenaries seeking to outbid others for work, but should we dispatch agents to speak with them, it would take very little pressure to have them work exclusively for us. The agents would need to remain to watch over our new friends, but I've been trying to place eyes on these positions for years.

Results

That was simpler than I would have hoped. The Imperial Counting House clerks were so shocked to have been discovered, and so fearful of being found out, they all but swore their loyalty to the Inquisition on the spot. My agents say they are behaving themselves so far - indeed, they sent "gifts" for you to prove their good faith - but we will watch them closely nevertheless. In the meantime, any efforts we make to gather coin in Skyhold will undoubtedly benefit from their placement. Leliana
