Mankind would never again benefit from His direct guidance and leadership. Yet the Master of Mankind was mortally wounded in battle with His fallen gene-son and had to be interred within the cybernetic life support mechanisms of the advanced psychic augmentation technology known as the Golden Throne. Eventually they were forced to take up residence within the Warp Rift called the Eye of Terror. Over the next several Terran years they were hounded from their remaining occupied territories in Imperial space during the campaign known as the Great Scouring. The forces of Chaos were forced to flee the Imperial Throneworld in complete disarray. The Loyalist forces ultimately proved victorious, though only just barely, and Horus was slain by the Emperor on the deck of his massive flagship, the Vengeful Spirit. The Siege of Terra, also called the Battle of Terra and the Siege of the Imperial Palace in Imperial records, is a reference to the final confrontation of the Horus Heresy that raged on Terra in 014.M31 between the Traitor forces led by the Warmaster Horus and the Loyalist armies of the Imperium of Man commanded by the Emperor of Mankind Himself.
