Changes

Leman Russ was devastated by his inability to save the Emperor. After the war was fully completed, and all resistance was crushed, Russ held a great feast, at which he declared he would be leaving, and would return for the 'final battle'. He then vanished, and is said to have gone into the Eye of Terror to continue hunting down the traitorous Marines who fought against the Emperor during the Horus Heresy. Another tale has it that Russ vanished after chasing a [[Kabal]] of [[Dark Eldar]] who had raided Fenris right into their city of [[Commorragh]]. Any evidence for either theories is yet to be presented and there is a large possibility that both are mere fables. The true whereabouts of the Primarch remains a mystery. Apparently [[Magnus The Red]] knows , but the Deamon Primarch and his Thousand Sons are not sharing that information with any outside their traitorous ranks.¹²

'''Harek Ironhelm''' was the chapter's Great Wolf during [[M32]]. Ironhelm sought for many years to bring Magnus to battle. Several times Magnus appeared to him in visions among the ruins of devastated cities and taunted the Great Wolf for his inability to stop him. After many fruitless efforts to catch up with the raiders , Harek became obsessed, and took to searching worlds along the edge of the Eye of Terror itself. Eventually , he found what he believed to be the Thousand Sons' secret base on Gangava and launched a full-scale attack against it. This was a deception to draw the Space Wolves from their homeworld, leaving it undefended; Gangava was held by a Chaos force allied to Magnus but it served only as a distraction, allowing a massive Thousand Sons' Fleet to besiege Fenris.

The Fang was held by only the 12th Great Company and their servitor-thralls. For forty days and forty nights the Thousand Sons assaulted the citadel. [[Bjorn]] the Fell-handed, most ancient of the Space Wolves dreadnoughts, was woken from his long sleep with 11 others^16c . Jarl Vaer Greyloc of the 12th company organised and leaded the defence on the front lines himself^16b . The assault was held at bay as the frigate Nauro, which had managed to flee from the [[Thousand Sons]] blockade, under the command of '''Haakon "Blackwing" Gylfasson''' escaped to Gangava to locate Harek Ironhelm^16a . On Gangava, the space wolves Space Wolves had to fight members of their fallen successor chapter the [[Wolf Brothers]]^16d , Ironhelm then realized that Magnus had played with him once again. When the warning about the Fang finally got to him, Harek Ironhelm returned to meet Magnus in battle on the slopes of the Fang itself. Ironhelm came back with the chapter just in time. He arrived by drop pod just after Magnus had slain Greyloc and his retinue as well as incapacitating Bjorn^16e . Despite the fact that Magnus was wounded, Ironhelm, an astartes, could not fight a primarch exalted to [[Daemon]]hood and he was slain. However, the return of the chapter made the [[Thousand Sons]] retreat in the face of imminent defeat. A lot of the remaining forces of the traitor Legion were killed during the assault of the Fang.
