Prepare to follow the most damned heroes in the Warhammer 40,000 canon in the impressive and intense new novel from Robbie MacNiven, Oaths of Damnation.

Recurring readers of this blog will know that I am constantly in the mood for fun and exciting Warhammer 40,000 action, which is why I listened to the awesome new book, Oaths of Damnation, the moment I could.  Written by new-to-me veteran Warhammer author Robbie MacNiven, a man with a lot of experience writing about complex Space Marines, Oaths of Damnation was one of the more intriguing Warhammer 40,000 books of 2024, and I really loved the opportunity to check out the infamous Exorcists Space Marines Chapter.

In the far, war-torn future, the Imperium of Man is under constant attack from the forces of the Chaos gods and their deadly daemon servants.  Few within the Imperium, even amongst the legendary Space Marines of the Adeptus Astartes, can fight against the daemons of Chaos on an equal footing, but there is one Space Marines Chapter, the Exorcists, that takes the battle to them in the most unorthodox and heretical of ways.

The Exorcists are an elite and secretive Chapter of Space Marines who make the ultimate sacrifice to fight the forces of Chaos.  Willingly accepting daemonic possession as part of their initiation, prospective Exorcists need to banish the daemon within themselves to join the Chapter.  Those who succeed become fierce warriors who are now resistant to the corruption of Chaos at the cost of their own fractured souls.  However, those that fail suffer a fate worse than death as they become Broken Ones, living prisons for the daemons summoned and expelled by the rest of the Chapter.  Few in the Imperium know the sacrifices that this Chapter makes to fight the enemy; if it were to become common knowledge, all the Exorcists would be put to the flame as heretics.

As such, when a dark conspiracy sees a Broken One containing a powerful daemon, the Red Marshal, escape from the Exorcists custody, the Chapter sends a unit of its elite Hexbreakers to hunt it down before their secrets are exposed.  Led by the dogged Almoner-Lieutenant Daggan Zaidu and powerful psyker Codicier Torrin Vey, the Exorcists strike force journeys to Fidem IV, a planet littered with ancient battlefields, to hunt down the Broken One and destroy the daemons within.

But as the Exorcists battle across the planet looking for their prey, it soon becomes clear that members of the Word Bearers traitor Space Marines Legion are on Fidern IV, seeking the Broken One for their own sinister purposes.  Worse, a dangerous connection exists between Zaidu and the Red Marshal, one that could endanger the entire mission.  Can the Hexbreakers succeed and hunt down the Broken One before it is too late, or will their Chapter’s darkest secret be unleashed upon the entire Imperium in a wave of blood?

Oaths of Damnation was a particularly intriguing and intense Warhammer 40,000 novel that really showcased MacNiven’s skill as an author.  Featuring a detailed look at a particularly cool faction in the Warhammer 40,000 canon, Oaths of Damnation was an excellent and exciting read that constantly grabbed my attention and refused to let go.

I really enjoyed the fantastic narrative contained within Oaths of Damnation, especially as MacNiven was able to produce a book that allowed him to tell his own distinctive story while also expertly highlighting the Exorcists Chapter.  Oaths of Damnation’s story starts off strong, with a look at the Broken One’s bloody escape from the Exorcists’ custody, which effectively sets up the Red Marshal as a deadly antagonist.  The following story moves at a quick pace as. With only a minimal amount of exposition and introduction, the protagonists set forth to Fidern IV to find the escaped Broken One, only to encounter opposition from the desperate daemon and the Word Bearers.

What follows is a series of intense and well-written battle sequences as the Exorcists pursue their target across the planet and fight against the various forces of Chaos.  MacNiven ensures a compelling story structure, as the protagonists face determined opposition, brutal fights and unexpected setbacks on the way to victory.  The author also spends time diving into the psyche of several key characters, which adds some intriguing intensity of the plot, especially as many find themselves distracted or conflicted by the mission.  MacNiven anchors the end of story on two massive action set-pieces that push the Exorcists to the limit and force them to face their internal and external daemons.  I liked some of the fun, if not unexpected, twists that MacNiven threw in in the lead up to the final battle, and the constant prophetic hints about dark events to come really enhanced the intensity of the plot towards the end.  The final confrontation is particularly impactful and moving, especially as there are some major sacrifices being made and all manner of carnage to behold.  I really appreciated the dark ending that MacNiven left the story on, and no-one should come into Oaths of Damnation looking for a happy ending.

MacNiven did an outstanding job capturing the dark and grim nature of the Warhammer 40,000 universe with his writing, and I felt that this was an extremely strong read overall.  While there are some complex lore events contained within, for the most part Oaths of Damnations was an accessible novel, even for those readers unfamiliar with the canon (although some basic Warhammer 40,000 knowledge would be helpful).  The author does an excellent job exploring the plot through the perspective of multiple complex characters, which resulted in a very compelling read, as many of the protagonists are forced to continually overcome their literal inner daemons.  I felt that this focus on damaged characters, as well as the intriguing examination of some unique Warhammer lore, helped Oaths of Damnation escape the ‘bolter porn’ label that many Space Marine novels are painted with.  That being said, Oaths of Damnation does have some particularly striking action sequences that fans of Warhammer 40,000 battles will really enjoy.  MacNiven clearly has a gift for showcasing Space Marines in all their martial glory with his writing, and you really get a sense of their power, intensity, and sheer destructive capability.  I also deeply enjoyed how he richly depicted their fighting capability and style, and the way in which he detailed the impacts of the bolt shells, the durability of the power armour, and the strength of their attacks, was honestly some of the best representations of Space Marines in combat I have ever seen.  I really cannot emphasise how impactful MacNiven’s writing style was, and Oaths of Damnation is a great book for all Warhammer fans, especially those buzzing for some Adeptus Astartes action after playing Space Marine 2.

A major highlight of this book for Warhammer 40,000 fans is the inclusion of the very cool Space Marines Chapter, the Exorcists.  A band of secretive and hidden Space Marines who willingly allow themselves to be possessed so they can learn to fight daemons better is an awesome concept, and MacNiven did an outstanding job showcasing this to the readers of Oaths of Damnation.  With only minimal lore dumps at the start of the novel, MacNiven ensures that the reader gets a sufficient and intriguing idea of who the Exorcists are and how they become lethal daemon fighters, and it proves fascinating to dive deeper and deeper into their Chapter as the book continues.  Not only is there is a great focus on how and why they damn themselves, but I also really appreciated the comprehensive way in which MacNiven tried to explore the other side effects of becoming an Exorcists, as well as the unique culture that they share.  The concept of the lingering bond that each Exorcist holds with their Never-brother, the daemon that possessed them, so much so that they still hear fragments of their voices and gain personality traits or combat abilities reminiscent of their former possessor, was particularly cool, and the author does an excellent job of showcasing it.  MacNiven also expertly covers the concept of the Orison Cults, social and ceremonial cults of the Exorcists dedicated to specific rituals and combat styles, and which serve a vital part in the larger Exorcists culture.  It was fascinating to see the ways that the now practically soulless Exorcists try to retain their humanity throughout their day to day lives, and how they replace the holes in their being with ritual and false comradery.  This combination of Exorcists’ lore, and MacNiven’s compelling dive into the deeper motivations and minds of its members, made for outstanding reading and it fun to see this complex and damaged Chapter in action.

I also have a lot of love for the compelling main characters featured within Oaths of Damnation.  While Space Marine characters in Warhammer fiction can sometimes be a little dull, the main two protagonists of this book, Almoner-Lieutenant Daggan Zaidu and Codicier Torrin Vey, each has a complex background and connection to the target that ensures that the reader is drawn into their story.  Zaidu’s is particularly fun, as Zaidu feels substantial guilt and anger at the damage caused by the Red Marshal, as it was the daemon that formerly possessed him.  Determined to end the connection between them once and for all, Zaidu lets his recklessness control him in many parts of the book, and it was deeply compelling to see how obsessed he became.  Vey on the other hand is a veteran Space Marines librarian, who stands as the beacon of knowledge to the group.  The man responsible for Zaidu’s possession by the Red Marshal, Vey bears a lot of guilt within himself, and he works hard to keep Zaidu safe from his own anger, impatience and desperation to kill his Never-brother.  Vey and Zaidu play off each other perfectly throughout Oaths of Damnation with their troubled mentor/mentee relationship, and MacNiven makes sure to hit all the right emotional notes to get the reader involved in their tales of personal woe.

In addition to Zaidu and Vey, MacNiven provides some fantastic alternative perspectives from several other members of the Exorcists who journey to Fidem IV.  As with the main two characters, each of these Exorcists are deeply troubled and damaged because of their former daemonic possession, and each then battles with the side-effects of the process, as well as the lingering taint of their Never-brothers.  This ensures that Oaths of Damnation has a rather dour tone to it at times, but seeing these damaged, yet highly determined and loyal Space Marines in battle is powerful and really drags the reader in.  The Exorcist characters are well balanced by a raft of compelling and distinctive villains, including a darkly charismatic Dark Apostle with great ambitions and a weary veteran Word Bearer who has started to question his role in the universe.  However, the most important villain is the fallen daemon known as the Red Marshal, who hungers for freedom and a return to power.  You get several intriguing trips into the Red Marshal’s mind, and I enjoyed seeing his boiling rage and determination to regain his god’s dark favour.  These great characters really helped elevate Oaths of Damnation’s plot, and I enjoyed seeing all their respective narratives unfold.

As usual, I ended up grabbing this cool Warhammer 40,000 novel on audiobook, which is my preferred way to enjoy books from this franchise.  While all Warhammer audiobooks are great, I felt that Oaths of Damnation came across particularly well in this format, and you really got dragged into the action and excitement as it was read out to you.  I personally found myself absorbing the complex lore surrounding the Exorcists a little better while listening to it, which helped with the overall impact of the story.  Oaths of Damnation also strongly benefited from the excellent narration of Charles Armstrong.  Armstrong, who previously impressed me with his narration of the Warhammer Crime audiobook, Bloodlines by Chris Wraight, did another excellent job in Oaths of Damnation as he expertly showcased the elaborate story with his voice.  I particularly enjoyed his compelling take on the various characters featured within the novel, especially the main protagonists, and he really captured their dark inner feeling and dedication in multiple scenes.  This proved to be an epic audiobook, and, with a runtime of just under 11 hours, it is one that dedicated listeners can get through fairly quickly.  I personally would recommend this format as the best way to enjoy Oaths of Damnation, or indeed any Warhammer 40,000 novel.

Oaths of Damnation was a particularly strong and exciting piece of Warhammer 40,000 fiction that I had an incredible time getting through.  Robbie MacNiven has produced another gripping and intriguing read that cleverly dives into the complex lives of a unique Space Marines chapter, and I loved every second of it.  An intense, dark and action-packed read, Oaths of Damnation really expresses the grimdark nature of the Warhammer 40,000 universe and you’ll have a very hard time escaping once you get sucked in.
