[1f], In that confused, armoured press, a place of bladed murder and where thoughts could slay, the senior Thousand Sons on the spot realised they had to eliminate Leman Russ then and there, or the day was lost. The Emperor had censured Magnus publicly for such activity and had warned him in no uncertain terms that he would be destroyed if he were to disobey the Edicts of Nikaea. Realising that no matter what he did, his and his fellows' fates were sealed, Ahriman discarded his original plan and spitefully tossed Wyrdmake's captured soul to waiting void-predators of the Warp before returning to his own body, prepared to live with the consequences of his actions and die fighting.

The Crimson King and the Wolf King met in battle, with the fate of an entire world balanced on the outcome, and they fought like the gods of ancient Terran legends. Further south, the port was a giant black stain on the horizon, its structures demolished in the wake of the Space Wolves' attack. From where Magnus descended, the sky split asunder, the very essence of the Warp leaking into realspace. As the 7th poured after him, Toron made his way into the Space Wolf lines, laughing hysterically at his sudden, invincible power.

The Adeptus Custodes were the first to be seen, making daring hit-and-run attacks from the backs of their powerful jetbikes. Early Moves Ahriman led the Scarab Occult in to reinforce the 15th Assault Infantry. So, to Magnus, the most obvious thing to do was to use his abilities to appear directly to the Emperor, not only allowing the essential truth of his news to be communicated, but also showing his father how skilled he was and how right he was to advocate the use of the complex psychic techniques that (to Magnus) lesser minds referred to as sorcery.

Psychically linked to the Titan, Captain Khalophis struggled to disconnect himself from it before he perished either in the explosion or feedback. Magnus had finally understood, after his forced psychic entry into the Hall of the Golden Throne and his direct mental communication with the Emperor, that he had been manipulated by Tzeentch, with whom he had apparently unknowingly consorted while desperately looking for a way to stop the emergence of the psychic mutations that were threatening to destroy his Legion. Feigning shock and horror at the Emperor's revelations, Magnus agreed to renounce sorcery and to lead his people away from the study of the occult, but he secretly dismissed his father's warnings. As Ahriman tried to concentrate enough to direct a force to fight off these approaching threats, a roar of agony from above, followed by a second, separate, louder one directed all attention upwards.
