Reach the slums
To begin this quest you must head to the Flooded Slums. This district is located in the southern area of Paris.
Find the smuggler's warehouse
Once you arrive, you must locate the warehouse. The raven should do a great job at that, easily finding the correct building.
Inside you need to examine several items, they glow blue when you use Odin Sight. The jars are on a wooden barrel, while the arrowheads can be found by the wall.
Afterwards go behind the iron bars and shoot the unstable floor. The boards will crack, letting you push the cargo and enter the room. Inside you'll find a letter.
Find and speak to Richardis in Saint-Julien Church
Next, you must find the queen. Head to the ruined church tower in the Flooded Slums. Your raven will easily find this place. Once you arrive, a short scene will play out.
Bernard claims he can show you where the smuggler dwells. Follow him to the sewers. Go down the sewers until you encounter enemies, who will promptly attack.
Kill the bandits
You must eliminate all opponents. During this encounter you need to watch out for Nolwenn's health. If she collapses help her stand back up, then talk to her after combat.
Speak to Nolwenn
During this conversation you have three dialogue options to choose from:
- Tell me, or else;
- I have coin;
- Toka sent me .
The first option isn't advised, as Nolwenn will get angry over your threats. She'll happily provide you info in exchange for cash, or, if your charisma is at least level 2, if you tell her you were sent by Toka.
Explore the tunnels and Reach the Sounth Bridge
Nolwenn will give you a key that'll help you reach further down the tunnels. Exiting the sewers, you'll find yourself in the lower parts of the wooden bridge. There are a few guards on the bridge, but you shouldn't alert them if you're careful.
Take the crates of explosive jars to bridge weak points
Your objective is to place the three red crates next to the bridge's weak points. That way they can get blown up during the siege.
Place the first crate by the barrel, next to the marker.
Take the second crate and look to your left. Next to the bridge there are some wooden poles and ropes which will allow you to get to the next weak point and plant the explosives.
Before taking the last crate move the wooden shelf so you can use it to jump onto the rope hanging underneath the bridge. Then grab the crate, jump onto the shelf, then on the rope and onto the floor. Now simply move the last object standing in your way to reach the objective, finishing the quest.
