Assassin’s Creed Valhalla: Siege of Paris — Hidden Ones Bureau guide
Find all the keys and you'll be able to unlock the Hidden Ones Bureau in Assassin's Creed Valhalla: The Siege of Paris.
Champlieu Ruins
The Champlieu Ruins are located in southern Amienois. Technically, this area is a lot closer to the northeastern end of Paris.
From above, these look like the ruins of an amphitheater. You’ll also see a wooden floorboard that you can destroy by shooting it with an arrow.
When you drop down, you’ll be in a narrow corridor with a few passageways.
You can slide through the small cubbyhole (watch out for rat swarms) to pick up an explosive jar. Slide through the next cubbyhole and blow up the wall.
You’ll find the Champlieu key here.
Before you leave, go further along the corridor and move the obstacle that’s barring the way. Use the cubbyholes once more to get past it. You’ll find a Book of Knowledge with the Goule Breath ability or its upgrade.
Anyway, let’s head to the next part of our guide to talk about the Diodurum Ruins.
