The Horus Heresy is a cornerstone event in the far future fictional universe created by Games Workshop as the campaign setting for its Warhammer 40,000 miniatures wargame. It is a relatively short but devastating galaxy-spanning civil war that engulfs the nascent galactic empire of the Imperium of Man early in the 31st millennium of the universe timeline; the war is a major cause of the science fantasy universe's dystopian environment. Initially described in wargame supplements published in 1988, and used as the setting for a 1989 Epic-branded tabletop miniatures wargame, it has been utilised since as background for several of Game Workshop's products.

The Horus Heresy has expanded in scope and standing beyond its original wargame-background role. Since the concept's introduction there has been an increasing number of related releases in several product categories and media. It is an ongoing project that has developed into a major, definitive component of the shared universe, and it has come into its own as a successful brand and product line for Games Workshop and its affiliates. In 2012, it was repositioned as a foreground element in the Warhammer 40,000 gaming system, thanks to the introduction of the stand-alone Horus Heresy miniatures wargame expansion.

Fictional

Setting

In the developing Warhammer 40,000 backstory, by the 30th millennium (or M30[1]:406) the "Emperor of Mankind", founder and head of state of the newly constituted Imperium of Man, has become a major proponent of Order in the Milky Way galaxy, and one of the most formidable enemies of Chaos and its forces. After consolidating his rule on Terra (Earth) and genetically engineering Legions of superhuman warriors (the Space Marines), he embarks, in late–M30, on a Great Crusade.[1]:168 The objective is to unify the millions of human space colonies scattered throughout the galaxy under the Imperium's banner. The Imperium proclaims an Imperial Truth of science and reason, and against religion and superstition  by extension weakening the influence of Chaos on the human race and its evolution. Promoting the notions of Order and Truth from a strictly human perspective as put forth by the Emperor, the Imperium has declared the Milky Way the exclusive, rightful domain of Humankind; it maintains that ruling the galaxy is the species' "Manifest Destiny".

While the Emperor is the Supreme Commander of the Crusade's many Expeditions, the Space Marine Legions and the rest of the Imperial military forces are eventually led by his genetically engineered progeny, a group of twenty Primarchs, who are in every aspect even mightier than Space Marines.[2]

Outline

Causes

In early–M31, two standard (Terran) centuries into the Great Crusade, in the final phases of the crusade, the Emperor promotes Horus Lupercal, his most trusted and versatile Primarch, to Warmaster (commander-in-chief of Imperial armed forces), and overall leader of the Crusade. The Emperor then leaves the Crusade and returns to Terra, where he remains in relative isolation. He relegates administration of the Imperium to a civilian authority  the Council of Terra  and in an undertaking kept secret even from Horus, oversees efforts to gain access to the Webway (an alien-built transdimensional tunnel system).[3] These actions test Horus' personal and mission-related resources, and exacerbate existing tensions among some of the Primarchs, especially those who feel slighted by other decisions of the Emperor or have grievances against their brothers.[3]

Soon after his promotion, Horus becomes the target of a conspiracy planned by the Gods of Chaos and executed by their allies and minions. It involves his near-fatal injury by an alien weapon called Anathame and supposed healing by the Serpent Lodge of the Moon of Davine; both events are designed to make Horus susceptible to the influence of Chaos and lead to his eventual corruption.[4] While the exact cause has been retoconned repeatedly, the current state is that during a ceremony designed to heal Horus of a mortal wound, he is shown a vision of the far future, in which the Emperor is worshipped as a god, and Horus and the other primarchs are forgotten (The irony being the Heresy is what leads to this future). As the Emperor primary edict is to stamp out religion of all forms, Horus sees this as the ultimate betrayal. Though another Primarch, his brother Magnus, tries to reach Horus by psychic projection and warn him of the treachery during his trance like state, the corruption spreads and prevents Horus from accepting his brother's guidance. He then turns against the Emperor, becoming the Traitor from the perspective of the Imperium. He plans a coup d'etat on a galactic scale, and ultimately leads eight other Primarchs, as well as their Legions and other forces, in war against the Emperor and all who stand with him. The betrayal and campaign are eventually labeled the Horus Heresy. Most of those who turn against the Emperor become, or already are, corrupted by Chaos.[5]:2

Conflict and resolution

Horus, outwardly still loyal, engages in subterfuge and secretly contravenes Imperial orders. He also issues orders designed to weaken and disperse forces deemed Loyalist, while simultaneously building covert alliances. Then, in the first open move of the Heresy, he succeeds in culling from the ranks of the rebels those persons and units still loyal to the Emperor.[6] During the opening stages of the campaign, the Loyalist side is shown to be beset by inadequate communication security and poor intelligence, its leaders stunned or in denial when faced with the enormity of events.

A subsequent operation, expertly directed by Horus and co-conspirators, involves the massacre of three Loyalist Legions that are sent by the Imperial authorities (along with other Legions that have secretly turned Traitor), to crush the rebellion.[7] Horus, continuing to assume the initiative following tactical and strategic successes, orders the bulk of rebel forces to the Sol (Solar) System and the heart of the Imperium. After a brutal in‑system space battle, they manage to make planetfall on Terra and to lay siege to the Imperial Palace, seat of the Emperor.

While the siege is a strategic stalemate, Horus is aware that massive Loyalist reinforcements are on the way. Lowering the shields of his flagship as a lure, the Emperor, Rogal Dorn, Sanguinius, and a force of Imperial Fists teleport aboard the flagship to confront him. Horus initially kills Sanguinius, and then is finally killed in single combat with his creator, while the Emperor is grievously wounded in the same action. The death of Horus leads to disarray among the invading Traitors, whose campaign is by this time also threatened by the imminent Loyalist reinforcements, and they hastily retreat. The Battle for Terra and the whole Horus Heresy campaign is effectively over.[8]

Aftermath

Horus' campaign lasts less than a standard decade,[lower-alpha 1] yet it is devastating in its scale, and the Loyalist victory comes at great cost. The losses in talent, knowledge, manpower, and territory result in a prolonged period of cultural, political, and technological stagnation and regression for the Imperium.

The barely-alive Emperor is interred at the end of the Battle for Terra in a complex life support device, a technological marvel known as the Golden Throne. The Throne also powers the Astronomicon, the navigation aid responsible for holding the Imperium together, as well as keeping the destroyed Webway entrance sealed, lest Daemons overrun the Earth. Entombed in the device, his decaying physical form is kept alive in a moribund state, and he is said to be able to express himself only psychically.[9]

A long and often violent period of "cleansing" the Imperium from Traitors, and rebuilding its institutions, takes place following the end of the Heresy. The majority of surviving Traitor forces flee to a Chaos dominion known as the Eye of Terror. There, they create their own empires and continue to harry the Imperium.[5]:5–7

Relevance

The Horus Heresy is a significant component of the Warhammer 40,000 canon, and since 2012 has been repositioned as a distinct foreground gaming element. Over the years, the concept evolved into the major reason behind the dystopian environment of the shared universe; in the current backstory of the universe's approximate real-time setting  ten millennia after the end of the Heresy[9]:6  the event is presented as shrouded in myth and distorted by disinformation. The future history detailed in Horus Heresy-branded material is depicted as lost, forgotten, or censored; yet situations caused by or related to the Heresy form the basis for much of the present context.

Real world

Introduction

The Horus Heresy was first referred to in a 1988 rulebook supplement to Rogue Trader (1987), the first edition of the Warhammer 40,000 wargame.[10]:6[11]:13It was expanded later in the same year in another supplement, the first volume of the rulebook Realm of Chaos, subtitled "Slaves to Darkness".[12]:240–243

The concept was also elaborated in the rulebook for Adeptus Titanicus (1988), the first Games Workshop Epic-branded tabletop miniatures wargame.[13] Epic-scale-miniature games may involve campaign- or theater‑level play that employs large forces, and provides for a correspondingly wider-scale background. This campaign setting included the establishment of the Horus Heresy as an important canon-based element.

Space Marine [1st Edition]

Finally in 1989 the Epic-series wargame Space Marine was introduced. Designed and developed by veteran Games Workshop associates Jervis Johnson and Graeme Davis, the game used model design and sculpting by Games Workshop division Citadel Miniatures.[14] Subtitled "Epic Battles in the Age of Heresy", it was the first Games Workshop product to directly involve the Horus Heresy concept, which was its sole campaign setting; by providing a justification for intra-Imperial warfare, the publisher was spared the effort and cost of different armies in the basic game boxes.[15] The boxed game contained army and scenery miniatures, accessories, and guides, while the rulebook included a multipage "Background" section, and annotated the rules with related storytext.[lower-alpha 2]

Expansion and continuity

In the years following its introduction as background for other products and as campaign setting for Space Marine, the Horus Heresy came into its own as a project; the transition mainly took place early in the 21st century. The concept was refined and further defined with expansions in areas such as art, gaming, literature, and multimedia. The continuing additions are set in the Heresy period of the universe, c. 30000 ("M31"), as opposed to the c. 41st millennium ("M41") era of most Warhammer 40,000 material. The additions may be released as stand-alone products or as parts of Horus Heresy series.

A significant development was the September 2012 initial release of the Horus Heresy miniatures wargame expansion. This in effect repositioned the concept as a foreground element within the main Warhammer 40,000 gaming system, thereby extending the related universe's active setting to the Horus Heresy era. In February 2013 the first Heresy-specific event, the 2-day Horus Heresy Weekender, was announced.

In addition to regular edition products, releases include special editions such as anniversary editions, collector's editions, web exclusives, and bundle offers.[16] However some components, including the majority of pre-Horus Heresy book series products or works, may be out of print, discontinued, or obsolete, and generally hard to find as of 2013.

Additions to the Heresy storyline are not necessarily in chronological sequence, and the overall narrative across all areas is nonlinear;[17] it may include events presented from different perspectives, and gaps that may presumably be filled in the future.

The expansions provide new or additional detail about the Horus Heresy, and their scope covers the entire Warhammer 40,000 universe c. M31; in some cases the newer material has led to continuity conflicts with older canon and other material. Overall, the information provided in the book series is generally assumed to be authoritative and superseding the older material.[18] Among other authoritative sources are the Horus Heresy wargame environment (especially the associated rulebooks), and other expansions.[lower-alpha 3]

"The Horus Heresy" is marketed as a sub-brand by Games Workshop, the Black Library (a Games Workshop publishing division), and Forge World, a modelling subsidiary. The associated product lines and related logos, places, names, devices and other components are copyrighted or trademarked.[lower-alpha 4] Games Workshop and affiliates have also released products that though not branded or classified as Horus Heresy items, are directly related to the fictional conflict or to specific facets of it.[19]

Art

Illustrations and images from a variety of artists, about the conflict and the related background, have been published in art books. The book series cover art has been separately released, as A2-size posters and in other formats.[20]

Art book series

This series consists of four "Horus Heresy: Visions" volumes, published between May 2004 and July 2006. They contain original art as well as images derived from the Horus Heresy card game. The volumes also collect edited, previously published Heresy-related magazine articles, and select rulebook information; in addition, original annotations, information, and short stories. The text, along with the art, greatly expanded the Heresy material. The series outlines the entire Heresy history, while providing additional background on it and the wider Warhammer 40,000 universe. The work was the result of contributions by numerous associates and staff of Games Workshop and its subsidiaries; select contributors are listed.

Literature

Literature directly related to the Horus Heresy consists of works in several formats and media, created by various authors; the majority are published by the Black Library, a Games Workshop imprint. As of April 2013 it included magazine articles, novels, novellas, and short stories.[37][lower-alpha 6] In the 2010s, some Heresy-branded literature appeared in other-language special editions before release in English.[lower-alpha 7][lower-alpha 8]

Book series

The Black Library started publishing the Horus Heresy book series in 2006, a derived brand that consists of titles with stories by a variety of authors. They provide detailed, multifaceted descriptions of the Heresy; the entire Warhammer 40,000 universe (c. 31000) is represented and taken advantage of. As of October 2013 the series consisted of 27 volumes, including full-length novels and novel-length compilations of novellas or short stories; the publisher had been adding several books per year since the start of the series' publication.

An opening scene-setting trilogy (Books 1–3) features the Luna Wolves Space Marine Legion, and portrays the fall of their Primarch (the Warmaster Horus) and the beginning of the Heresy. The series narrative was subsequently expanded to include the actions of other Legions and of various organisations and individuals. In the timeline of the Heresy, by Book 24 (originally published December 2012) this series was at about the half-way mark of Horus' campaign.

Most titles are published in multiple media and formats: as mass-market and trade paperbacks, in hardcover "premium" edition, as regular or "enhanced" e-books, and as abridged or unabridged audiobooks and e‑audiobooks.[37] A number of stories have appeared in other official publications, sometimes before the release of the relevant book series titles; compilation stories have also been pre- or re‑published in stand-alone editions.[lower-alpha 9]

The first regular UK paperback edition of the book series titles is listed below. Since November 2010, publishing of titles in this edition has sometimes lagged behind other editions or formats by several months.

Notes

  1. As of April 2013, there had been no complete official timeline of the Horus Heresy; dates for some constituent events were published in several official sources (such as in Troke et al. 2012, p. 168), while other dates were implied by official material (e.g. Abnett 2006, p. 14). Some information was also provided by a Black Library editor at a Horus Heresy fan online discussion site (Marcoos et al. 2013, original poster quotes Black Library editor Laurie Goulding in related discussion thread).
  2. See also § 1st edition (in Epic (game)). Subsequent editions and versions of the game, published by or licenced from Games Workshop, did not explicitly or directly utilise the Horus Heresy concept.
  3. A more general perspective on continuity and canon within the Horus Heresy and the Warhammer 40,000 universe is offered by one of their authors in Dembski-Bowden 2012b, ¶¶ 12 and following
  4. The Black Library had briefly expanded into Horus Heresy merchandising, a project that was abandoned in favor of the core product, see Black Library Online "Frequently Asked Questions"
  5. Warmaster, the free "Horus Heresy companion game", focuses on a confrontation aboard Horus' flagship at the close of the Battle for Earth (Johnson 1993b). It has the same subject matter as the short story "The Emperor and Horus" which was first published in King 1990. The publication containing Warmaster included two background stories related to both games, see listing on this page. [A fantasy miniatures wargame also entitled Warmaster, originally published by Games Workshop in 2000, is unrelated].
  6. In November 2012 the publisher announced plans for a future series of Horus Heresy graphic novels, based on new stories or perspectives of the Heresy. According to the publisher, the first title, written by Dan Abnett and drawn by Neil Roberts, will be entitled Macgragge's Honour. It will be a sequel of Know No Fear, Book 19 of the Horus Heresy book series. This new series' titles are scheduled to be first released in limited hardcover edition (The Black Library Team 2012b).
  7. 7.0 7.1 7.2 One original novella, authored by Gav Thorpe for a compilation in the Horus Heresy book series, was pre-published in another (German) language months before related information appeared in the publisher's English-language communications. It was released in limited edition by the Black Library for Games Day Germany 2012 (Games Workshop 2012, [page at Games Workshop's localised website]). The story is entitled Die Toten zu Ehren in German; the title's first release in English was as an audio drama, see Honour to the Dead.
  8. 8.0 8.1 "The Gates of Terra" short story was originally published in the November 2012 Games Day France Chapbook compilation, along with a print edition of Graham McNeill's "Kryptos".[38]
  9. See "The Lion", and Thorpe (2012b). Also see note ,[39] and § Media and editions (in Horus Heresy (novels)).
  10. The novella "Feat of Iron", again by Nick Kyme, included in Dunn (2012a) and also released in standalone edition,[70] is a complementary story. It takes place at the same time frame and campaign theater.
