Following the Battle of Beta-Garmon, which represented the last major Loyalist resistance beyond Terra, the door to the Sol System had been opened wide. Horus finally mustered his forces on Ullanor Prime after almost a solar decade of war. They included the Sons of Horus, World Eaters, Emperor's Children, Thousand Sons, Death Guard, and Iron Warriors, each commanded by their respective Primarchs.

As a vast taritor horde of traitor Astartes, Imperial Army, Beastmen, Mutants, Daemons, Titans, and other horrors massed on the horizon, only some 70,000 defenders mustered on the Delphic Battlement before the processional to the Eternity Gate. These were mainly Blood Angels and Imperial Army, but Imperial Fists, White Scars, Legio Ignatum, and Mechanicum loyalists were also represented. Corswain offered to send his own forces defending the Astronomican to aid the defenders, but Sanguinius refused them to the vital nature of the Dark Angels Paladins mission. [22a]

Devastated by the Space Wolves' destruction of his Legion's precious storehouses of knowledge about the Immaterium and sorcery in their lost Prosperine capital city of Tizca, and having turned to the Chaos God Tzeentch to save himself and his Astartes Legion, Magnus pledged his allegiance and the allegiance of the Thousand Sons Legion to Horus and Chaos in retaliation against the Emperor for this betrayal. The Thousand Sons were en route to Terra where they would link up with Horus' forces. Upon discovering the shields of the Vengeful Spirit down, Malcador the Sigillite alerted the Emperor, still struggling to keep the Golden Throne and its adjoining Webway Gate stable. Upon learning of the news, the Emperor knew it was time to act and end Horus, even though he was certain it was a trap. Rogal Dorn, Sanguinius, Vulkan, and Valdor were all called to his side for the coming battle, and all objected to the Emperor's plan to personally teleport aboard the Vengeful Spirit. [24f] However the Emperor overruled his sons, commanding Valdor and Dorn to come with him while Sanguinius took control of loyalist forces on Terra and Vulkan stay behind to oversee the potential failsafe on the Golden Throne. [24g] Sanguinius flatly objected to his fathers request to stay behind, telling the Emperor of his prophetic death at Horus' hands and his intention to defy fate by defeating his traitorous brother instead. This was enough to move the Emperor to change his mind. Four company's were organized for the assault: the Hetaeron Guard led by the Emperor, another Custodes company under Valdor, a mixed force of Sanguinary Guard and Blood Angels 1st Company under Sanguinius and Raldoron, and Huscarls under Dorn and Diamantis. The operation was codenamed Anabasis. [24h] Malcador took his place upon the Golden Throne in the Emperor's place, an act that would cost him his life. For that, The Emperor renamed Malcador the Sigillite to Malcador the Hero.
