Cover Description
As the flames of treachery spread throughout the Imperium, Horus plots to subvert or destroy all those who would stand against him. On Mars, home world of the Mechanicum priesthood, the great manufactory-cities have long produced much of the weaponry required for the expeditionary fleets across the galaxy — making the world invaluable to whoever controls it in the coming war. Now, the Warmaster's agents begin to stoke the fires of rebellion, turning the loyalist forges and the mighty Titan Legions against one another. And, with whispers spreading of an ancient terror lurking beneath the Red Planet's surface, the Dark Mechanicum rises...[1]
Plot Summary

The following paragraphs contain spoilers for: | Mechanicum (Novel) |
Mars, c. 739.M30. Three Knights of Taranis investigate the landing of the first ship to arrive from Terra in centuries, and Taymon Verticorda is the first to kneel in front of the Emperor as Omnissiah.[2c]
Part One: PRINCIPIA MECHANICUM
005.M31. Terran Transcriber Dalia Cythera stands accused of tech-heresy, but instead of being executed is brought to Koriel Zeth's Magma City on Mars. Raf Maven and two of his fellow Knights of Taranis are defending Ipluvien Maximal's reactors against feral servitors when he picks up suspicious auspex readings from the reactor complex.[2d] Cythera meets Zeth, who sought her out for her innate understanding of technology and wishes her to assist in the construction of the Akashic Reader. Maven faces Protector squads and a machine of unknown design, which destroys one of Maximal's reactors.[2e]
At the fortress of the Legio Tempestus, divided theologies and loyalties clash in a meeting convened to discuss the attack on Maximal's facilities. Brought into a team of technical servants, Cythera is tested as Zeth tells them to build a cognitive enhancer whose schematics have confounded adepts for centuries.[2f] Fabricator General Kelbor-Hal meets with Regulus, Mechanicum representative to the 63rd Expedition Fleet, who asks for Mars' loyalty to Horus Lupercal in exchange for access to the Vaults of Moravec. The cognitive enhancer is completed, thanks to improvements on the original design, and Zeth proclaims it will help usher in a new age of knowledge for humankind.[2g]
Fabricator Locum Zagreus Kane notices that logistical issues disproportionately affect Legiones Astartes not directly supporting the Warmaster, and informs Kelbor-Hal. Cythera and her friends are led deep under the Magma City, and find out that the Akashic Reader requires thousands of psykers to function.[2h] Indeed, the device will enable the empath Jonas Milus to access the aether and the sum total of all knowledge in the universe. Impatiently observing repairs on his mount, Maven swears to kill the machine that evaded him. Beneath Olympus Mons, Regulus leads Kelbor-Hal to the Vaults of Moravec, opening the gates with scrapcode that infects the Fabricator General.[2i]
The cognitive enhancer is installed while Cythera's concern grows regarding the Reader’s effect on its human components. As scrapcode interferes with communication all over the planet, Princeps Indias Cavalerio cuts short his maniple's patrol around Maximal's reactors upon learning that Legio Mortis is marching towards the fortress of Tempestus.[2j] The Reader's first test turns to disaster as psychic energy overwhelms the chamber, and Cythera takes in Milus's last words and vision. Mortis engines cross the Tempest Line, an action akin to a declaration of war.[2k]
Part Two: SYSTEMAE MECHANICUM
Cavalerio calls Mortis's bluff and refuses to open fire. The intruding Titans walk away, but the strain of the march overloaded Cavalerio’s Imperator, killing the engine. In the pallidus, a scavenger named Quinux stumbles on the Kaban Machine, Maven's nemesis, and is killed by it at the behest of Lukas Chrom. At Olympus Mons, Kelbor-Hal and Regulus look upon the mustering of warp-infused servitors and Skitarii, acknowledging Zeth to be a threat because of her Noosphere and the Reader incident.[2l]
As the scrapcode wreaks havoc all around the planet in the Death of Innocence, Cythera awakes from a week-long coma. Hiding Milus's message from Zeth, she confides in her teammates: she experienced a vision related to a dragon in a benighted maze, and they surmise this refers to the Noctis Labyrinthus. Cavalerio wakes up in an amniotic fluid tank, and his new famulous Agathe starts guiding him towards adjustment and acceptance.[2m] Word of the death of Isstvan III reaches Mars, and Kane suspects Kelbor-Hal of having released the scrapcode. Patrolling around the Magma City, Maven and Cronus go off-mission to hunt down the Kaban Machine. Plagued by dreams of a dragon and a hooded man, Cythera decides to leave and seek them out.[2n]
Cavalerio is deemed too hot-headed at the moment to resume command of Tempestus, leaving Sharaq to act as Princeps Senioris. Awaiting a mag-lev train, Cythera and her friends – minus Mellicin Oster – are approached by Rho-Mu 31, who accompanies them as he has been ordered to protect Cythera by Zeth. The latter learns of their intentions from Oster and has her wipe her own memory of that knowledge.[2o] Ambassador Melgator, accompanied by Tech-Priest Assassin Remiare, comes to the Magma City to assess the loyalty of Zeth, who openly denounces Kelbor-Hal as a traitor and her unbelief in the Machine God. Remiare tracks Oster down and tortures her for Cythera’s whereabouts.[2p]
Sharaq keeps Cavalerio appraised of the situation, as Cythera and friends see concerning traces of the planet's unrest. Melgator leads a force to take the Magma City, but backs down when faced with Knights of Taranis.[2q] The mag-lev train is attacked by the Kaban Machine, which Cythera manages to fool into thinking she and her friends are dead. The Legio Tempestus musters for war and Kelbor-Hal unleashes the Dark Mechanicum forces on the few forges still capable of resisting.[2r]
Part Three: ORIGENS MECHANICUS
As the Martian Civil War erupts, Cythera’s team reaches the Noctis Labyrinthus and the entrance to the dragon’s lair. Maven and Cronus find the wreckage of the train and keep after the Kaban Machine. On Terra, Malcador the Sigillite charges Rogal Dorn to secure Mars and kill Horus on Isstvan V.[2s] War comes to the Magma City, and Legio Tempestus ambushes the engines of Mortis in the forge's ruined outskirts. The loyal adepts are informed of the Imperial Fists' plan: to secure the main facilities of Astartes weapon production, then provide relief to the besieged Zeth and Maximal. Cythera and her friends navigate the cave complex in the labyrinth, stumbling upon Semyon, Guardian of the Dragon.[2t]
He leads them to a place of eldritch geometries and imparts upon Cythera the knowledge of his duty. Kane's forge is secured, but the other Imperial advances falter against the forces of the Dark Mechanicum. Cythera is shown the confrontation between the Dragon and the Emperor, the latter imprisoning the former as destruction is beyond his power. She also learns that the Emperor orchestrated the creation of the Mechanicum and its belief in the Omnissiah. Semyon makes her the new Guardian and turns to dust.[2u] With enemy forces within range, Sigismund forcibly evacuates Kane with whatever materiel can be recovered, leaving Zeth and Maximal to their fates. Cythera and Rho-Mu 31 walk their two remaining companions out of the cave complex, but they are met by the Kaban Machine. They are saved by Maven and Cronus, who destroy the machine.[2v]
The Legio Tempestus and the Knights of Taranis sell their lives dearly in the last stand for the Magma City, dispatching most Mortis engines and killing Melgator. After Maximal detonates his reactor chain, Zeth goes to destroy her own forge but is shot down by Remiare.[2w] The last Tempestus engines fall and self-destruct as Zeth reveals she has infected the assassin with a trip-code, incapacitating her. The adept shuts down the city's structural safeties, releasing an ocean of magma that obliterates the remaining combatants, including the Mortis Imperator Aquila Ignis.[2x]
Cythera starts her duties as Guardian of the Dragon, but the book containing the truth of the Mechanicum’s origins has been taken.[2y]
