There’s a book of knowledge in Briggworth (Suthsexe) in Assassin’s Creed Valhalla.

Here’s how you can get the book of knowledge in Briggworth in AC Valhalla.
Book of knowledge location
The location of the book of knowledge in Briggworth is shown in the map below, marked by the book symbol.
It’s in the keep of the fort.
How to get the book of knowledge
The book of knowledge is at the top of the tower.
To enter the tower, look for the wooden structure in the middle. You can enter through the window.
Inside, you’ll see stairs. Follow the stairs all the way to the top.
You’ll then see a barred door and a guard. Get rid of the guard first.
To enter the room where the book is, climb above the room. You’ll see a movable shelf.
Move it to the right side and in the next area, you’ll see a hole that can be used to go down.
After jumping down, the book is right there.
Get the book of knowledge and you’ll unlock the Incendiary Powder Trap ability upgrade.
