A Book of Knowledge is the name given to a book containing information on particular skills used in combat, be it ranged or melee.

In the late 9th century, during her many travels in Europe, Viking shieldmaiden Eivor Varinsdottir of the Raven Clan read a number of these books and expanded her skillset. Many of these books were found inside churches like the Cliffside Monastery or the Kells Abbey, fortresses like Dover Fortress, and ruins such as the former Hidden Ones' bureau at Diodurum. While exploring her visions of Odin's memories, she also found and read four more of the books.
