From the author of The Siege of Castellax comes an exclusive short story that takes you deeper into the events of the novel. As the feral green-skinned orks swarm across the fortress world of Castellax, Iron Warriors Over-Captain Valax and Techmarine Oriax embark upon a dangerous mission that could decide the course of the war. But can the Iron Warriors trust one another, or will they fall to infighting and treachery?
The story here presents a part of C.L. Werner's novel as a stand-alone experience. It focuses on Over-Captain Vallax (written Valax in the short story) and Fabricator Oriax, and adds a few more scenes to one crucial mission of Vallax's raptors as seen in The Siege of Castellax.
This short story was written as part of Werner's preparation for the full novel, as he explained in a blog back when this story was released. It was nice to see the concept of these events having been in his head from very early on, and a lot of them was directly used in the novel, with some minor details changed around (Vallax's name, Rhoodan's rank and so on).
As a stand-alone Iron Warriors short story it worked well, though not as well as it did in context of the full Siege. Being an early concept story, it has some rough edges and lacks the significant depth of the characters, but it was a good read nonetheless.
If you have an interest in The Siege of Castellax, this might win you over. But if you have read the novel, you may want to skip this, as it has little new to provide.
