Our continuing look at lore from the Horus Heresy focuses on the Ultramarines this week. Discover their storied history from the earliest days on Terra to the beginnings of the galactic civil war.

Originally found in The Horus Heresy: Book 5: Tempest – first published in 2015 – this classic “Black Books” lore takes us from the earliest battles of the XIII Legion at the end of the Unification Wars through to the discovery of Roboute Guilliman and the creation of Ultramar. There are details of the Legion’s exemplary battles, a look at how they’re organised, and artwork showing off the Ultramarines’ heraldry.
Ensure your XIII Legion army is doing things by the book with the Ultramarines Praetor. Then, join us next week as we look at the biggest tragedy for the sons of Guilliman – the war at Calth.
