Under Watchful Eyes drops you into Stoneward Post at a low level, with your gear possibly confiscated and every guard in the camp ready to swarm the moment Mert’s cell opens. The objective text tells you to walk him out through the main gate, which sounds like a long fight. It isn’t, if you know about the side door.
Quick answer: Steal the Prison Keychain from the table in the upstairs room while the captain has his back turned, unlock Mert’s cell, then use that same key on the locked door in the lit alcove on the north side of the overseer’s tower. It leads to a second locked door and out past the walls, which completes the escort without the main gate fight.
Under Watchful Eyes: Quest start, objectives, and reward
This is a sub-quest of The Firebrand. It begins on its own the moment you finish that mission by speaking to Mert down in the dungeon, and it only appears if Mert survives The Firebrand. Everything takes place inside Stoneward Post in the Briar Sloughs.

Fastest exit: the locked door on the north side of the tower
The objective wording is misleading. You do not have to use the main gate at all, and the quest still registers as complete if you don’t.
Tip: this rear door doubles as an entrance. Once it’s unlocked, you can come back into Stoneward Post later without handing over your weapons at the front gate, though that means at least two trips since you need the keychain first.
Main gate route: two wooden gates and Ceribus, the Scornful
If you want the loot and the XP from the garrison, take the long way. It’s a real difficulty spike at this point in the game, so quicksave between encounters.


Ceribus, the Scornful loot
| Item | Amount |
|---|---|
| Denarius | 130 |
| One-and-a-Half Mead | 1 |
| Minor Fortitude Paste | 2 |
| Brencis’s Elite Soldier’s Fibula | 1 |
| Ring of Purging (amulet) | 1 |
| Wicked Falchion | 1 |
| Adrenaline Rush Manual | 1 |
Confirming the quest is complete and the final Mert conversation
Crossing the boundary outside the post plays a short loading screen, and you’ll see the QUEST ENDED banner for Under Watchful Eyes along with the 250 XP payout. That banner is your confirmation; the journal entry closes at the same time.

Before you talk to Mert on the other side, check your hunger. Feed on animals nearby if Coen is running low, otherwise he can drink from Mert automatically during the conversation. Assuming hunger is under control, pick The almshouse in Svartrau to send him somewhere safe.
Note: if you also freed Mert’s wife back at the mill, both of them turn up again later in Svartrau.
The choice really comes down to what you need. The side door is the clean, low-risk finish for an underleveled Coen, while the main gate route pays out a falchion, an amulet, an ability manual and a pile of Denarius for the trouble. Either way, the quest closes the same and Mert walks out alive.
