FAQ
Since the original release of Warhammer 40K, there have been several hundred novels written in the franchise by a plethora of authors. It’s far from required to read them all, but it’d be an impressive feat.
Do Warhammer 40K Novels Affect My Tabletop Game?
No. Some beginning players think that the novels are directly tied to gameplay, but there’s little to no link. These books are for extracurricular lore and enjoyment.
Are The Codexes Warhammer Lore?
Warhammer codexes are books that dive deeply into the art, lore, design, and behind-the-scenes story of individual armies. These are full of lore, but we’ve separated them into another category, as your enjoyment of them depends on whether you enjoy the subject of the codex. We strongly recommend them if you find one that interests you.
