A Siege of Terra Omnibus
This collection combines two novellas into one volume, exploring different aspects of the Siege of Terra – one from the gene-manipulation labs that ultimately produced the Space Marines, and another about Magnus and his fall to Chaos.
READ IT BECAUSE
These two tales shed light on the Horus Heresy, adding important context to both the creation of the Space Marines and the plight of Magnus, a tragic figure if ever there was one. Both of them offer new insight into the greater war, and feature their own fascinating, if grim, narratives that you won't want to miss.
This is a pre-order title, available to download from 23 Jan 2026.
THE STORY
In Sons of the Selenar, a ship carrying members of the Shattered Legions is diverted to Luna, where they face the harsh reality of what it took to create the original Space Marines.
In Fury of Magnus, the Crimson King seeks a fragment of his soul trapped in the most defended place on Terra – the inner sanctum of the Imperial Palace. While the war rages around him, he must decide for himself if the risk is worth the prospect of restoring himself.
