Tracking down the ancient remnants of the Hidden Ones adds an immersive layer of lore and strategy to your journey across ninth-century England. In Assassin's Creed Valhalla, recovering the scattered historical manuscripts left behind by the predecessors of the Brotherhood rewards players with unique narrative insights and legendary equipment. Knowing exactly where to look for these elusive records can save eager players plenty of real-world hours spent wandering through overgrown ruins.

Uncovering the Bureau of Ledecestre

The historical hunt begins in the heart of Ledecestrescire, where an abandoned underground facility conceals the first vital manuscript. Players must navigate to the old Roman ruins located northeast of the main town and look for a hanging cargo net filled with heavy stones. Shooting the weak link drops the weights, smashing open a hidden floor entrance that leads directly down into the dark chambers below.

Once inside the flooded corridors, you must follow the linear path and slide under a small wall gap to reach the primary study area. The hidden scroll rests on a wooden desk right next to a treasure chest containing valuable armor pieces. Collecting this item initiates your progression toward solving the grand mystery surrounding the Brotherhood's sudden departure from the region.

Exploring the Hidden Chambers of Lunden

Moving south into the bustling streets of Lunden reveals another secret outpost known as the Londinium Bureau. Finding the entrance requires exploring the outer northern walls of the city until you spot a circular wooden structure surrounded by tall stone pillars. Leaping from the top beam allows Eivor to drop safely into an isolated pool of deep water hidden below the surface ruins.

After swimming through the submerged tunnel, players will find themselves inside an isolated chamber with a breakable wooden wall barrier. Shooting an explosive arrow through the iron grating detonates nearby jars, completely destroying the obstacle blocking your path. The ancient parchment lies on an ornate table, waiting to be claimed alongside the legendary Hidden Ones mask.

Navigating the Heights of Colcestre

Deep within the forested territory of Essexe, the Camulodunum Bureau presents a unique navigation puzzle centered around water mechanics and locked doors. The subterranean entrance is located near the southern ruins of Colcestre, hidden beneath a heavy stone slab that requires a nearby oil jar to blast open. Descending into the flooded crypts requires precise platforming along a series of wooden beams suspended over deep pools.

To bypass the locked doors, you must swim to the flooded northern corridor and dive underwater to locate a hidden key resting on the floor. Returning to the main room allows you to unlock the side armory where the vital document is securely stored. Grabbing this piece completes another significant portion of Hytham's ongoing historical research questline.

Securing the Final Secrets in Jorvik

The final chapters of your academic expedition take you north to the historic city of Jorvik, home to the Eboracum Bureau. The entrance is located inside a suburban graveyard, where a breakable wooden floor panel reveals a long ladder leading down into the municipal sewer system. Navigating the dark aqueducts requires careful navigation to avoid getting disoriented by the winding underground paths.

Players must swim across a large internal lake and climb up the wooden scaffolding to reach a lit office space. The last manuscript is positioned near a detailed map of England, surrounded by old books and unique treasure containers. Delivering the entire collection back to the settlement settlement settlement unlocked the full truth of the Brotherhood's ancient history.
