The Black Library is a division of Games Workshop (formerly a part of BL Publishing) which is devoted to publishing novels and audiobooks (and has previously produced art books, background books, and graphic novels) set in the Warhammer Fantasy Battle and Warhammer 40,000 fictional universes. The publishing company took their name from Warhammer 40,000, where the Black Library stored knowledge of Eldar race, the sinister Chaos, and the haunting Necrons.
