Emperor of Mankind vs Horus Lupercal Horus Heresy Siege of Terra Book Cover

In the climactic moments of the Horus Heresy, the Emperor of Mankind faced his once-favored son, Horus Lupercal, aboard the battle-battered Vengeful Spirit. The scene was a tragic culmination of son against father, loyalty against betrayal, with the fate of the Imperium hanging in the balance. Horus, consumed by chaos, wielded immense power, matching the Emperor blow for blow in a titanic struggle that shattered the walls and floors around them.

As the battle raged on, the Emperor hesitated, still seeing a glimmer of the son he once loved, and this hesitation cost him dearly. Horus, fully corrupted, struck the Emperor with devastating force, nearly ending the life of the master of mankind. It was only through the intervention of the loyal Custodian, Rogal Dorn, that the Emperor found the strength to unleash his full power, annihilating Horus in a blinding flash of psychic energy, but not without being mortally wounded himself. This moment marked the tragic end of the Heresy and the beginning of the Emperor’s eternal internment on the Golden Throne.
