Warhammer 40K Horus Heresy

The Horus Heresy is one of the most defining and tragic events in the Warhammer 40,000 universe. Set ten thousand years before the grimdark present of the Imperium, it tells the story of how Horus Lupercal—the Emperor’s favored son and Warmaster—was corrupted by the Chaos Gods.

Once a symbol of unity, Horus led half of the Space Marine Legions in a devastating civil war against the Imperium. Brother turned against brother as the galaxy descended into bloodshed. The war shook the foundations of the Imperium and forever changed the course of humanity. It was not just a war of armies, but a war of ideals, betrayal, and destiny.
