This is a court quest aimed at enraging Ambrus and increasing your infamy level. It is one of three quests in the Draining Dungeons / Ambrus's Dungeons questline. To begin this quest, approach the outpost located in the southeastern part of Briar Sloughs.
Time Segments: 3
Ambrus's soldiers bring prisoners to secluded prisons. Might be a good idea to disturb this operation.

1. Investigate the outpost
I likely won't get an invitation - but I can still see what I'm dealing with here. I'd better be ready for a fight.
Enter through the gate into the courtyard of the farm located here, and kill all soldiers who attack you.
2. Investigate the camp (3 Time Segments)
I should search the camp for clues as to what happened here. For some reason, the soldiers packed up the carts with the blood cargo and prepared the camp itself to be burned.
Simply try entering the main building located within the camp. You will find that the door is locked and you need a key.

2.1. Follow the footprints
I found some mysterious footprints. I should check where they lead to.
The tracks will lead you to a nearby barn.

On a table inside the barn, you will find the key you need.

2.2. Go back to the door
I found the key - I can open the door now.
Return to the entrance door of the main building. With the key in your possession, you can now head inside.

2.3. Interrogate the chief jailer
I should question the chief jailer. Maybe he'll tell me why the soldiers were preparing to burn the camp.
Inside the building, you will find a terrified chief jailer begging for his life. You will be able to choose how to handle him.
- You're not going anywhere - You will step out onto the courtyard, where you will have to defeat him in combat.
- Pay me and you walk. - You spare his life, and in return, he tells you about his stash and gives you a map showing its location.

2.3.1. (Optional) Kill the chief jailer
This coward deserves just one fate.
If you decided that the jailer deserves to die, you will head out to the courtyard and have to defeat him in combat.

Loot his body to get the map showing the location of his stash - Treasure Map: Hidden Stash (Quest Item).

Before heading outside the camp to look for the jailer's stash, take a look at the Ledger lying on the table.

2.4. Look for the fallen tree
A fallen tree should demark the location of potential hidden stash. Let's find it.
The fallen tree trunk you are looking for is located outside the camp walls, on its northeastern side. In a hollow at the base of the trunk, you will find a small box.

Inside, you will find another proof that the Boyars do not care for one another.

3. Endings
If you let the jailer go free. Reward: 250XP, Skill Point x1
The jailer offered me a map pointing to a hidden stash in exchange for his freedom. I decided to let him go.
If you decided to kill the jailer, a duel will break out between you. Reward: 250XP, Skill Point x1
I gave the cowardly jailer a chance to win his freedom by beating me in a duel. He failed. Whoops.
