Haunted by his dreams, Ironhelm becomes increasingly determined to bring the Thousand Sons to battle and finish what the Space Wolves started at Prospero more than a thousand standard years before. After receiving word that the Traitors are massing on the world of Gangava, Ironhelm launches a full attack without hesitation, leading eleven entire Great Companies into battle. Having laid his plans over hundreds of Terran years, Magnus the Red arrives on Fenris with the remaining fighting strength of his Traitor Legion. Only a single Great Company remains to defend The Fang, and Bjorn the Fell-Handed is roused from his slumber to lead a guerrilla campaign against the Traitor forces. The Thousand Sons breach the great gate of The Fang, but not before the Wolf Scout Haakon Blackwing escapes the siege to bring word to the rest of the Chapter. The Space Wolves return in force to drive their hated enemies from their homeworld.

After a grueling three-year siege in which the Renegade forces suffer massive losses, Wolf Lord Kyrl Grimblood returns to Fenris following the conclusion of his campaign in the Eye of Terror and smashes into the rear of the Traitor lines. Caught between the impenetrable defences of The Fang and Grimblood's fleet, Bucharis' armada is forced to withdraw from Fenris, abandoning a large part of their fighting strength to their fate.The Ecclesiarchy Comes to Fenris (886.M41) - A delegation of Ecclesiarchy officials approaches Fenris, intending to assess the Space Wolves after hearing rumours of their worship of false gods.

However, it is not a lesson learned, and almost a standard year later the Ecclesiarchy and three Orders Militant of the Adepta Sororitas attempt to enter Fenrisian space in force.
