Beginner’s Guide to Warhammer Lore

The worlds of Warhammer are home to some of the richest, most expansive fictional universes in all of popular culture. With decades of novels, codexes, campaign books, and supplementary materials, the lore of both Warhammer 40,000 and Age of Sigmar can seem impossibly vast to newcomers. But that depth is also what makes these settings so compelling. There is always more to discover, always another layer to peel back, always another story that recontextualises something you thought you understood.

This guide is designed to help you find your footing in the worlds of Warhammer, whether you are a brand-new hobbyist who wants to understand the setting behind the miniatures on your shelf, or a returning player catching up on years of narrative development. We will introduce you to both major settings, point you toward the best starting points for deeper reading, and explain how the lore connects to the tabletop experience.

One important thing to understand about Warhammer lore is that it is deliberately written to support multiple interpretations and perspectives. Games Workshop describes its settings as places where anything is possible, and this open-ended approach means that your own army’s backstory is just as valid as anything in the official publications. The lore is there to inspire and inform your hobby, not to constrain it. Use it as a starting point for your own stories, and do not worry about getting every detail perfectly right.

The Warhammer 40,000 Setting in 60 Seconds

It is the 41st Millennium, and humanity is locked in an unending war for survival. The Imperium of Man is a galaxy-spanning civilisation of unimaginable scale, bound together by faith in the God-Emperor who has sat entombed on the Golden Throne of Terra for ten thousand years, his psychic power holding back the tides of Chaos that threaten to engulf reality itself.

The Imperium is beset on all sides. The Chaos Gods, ancient entities of malevolence that dwell in the Warp, a parallel dimension of psychic energy, corrupt souls and send armies of daemons and traitorous Space Marines to tear the Imperium apart. Alien races pose existential threats: the Tyranids are an extragalactic swarm that consumes all biomass in its path, the Necrons are ancient machine-beings awakening from millennia of slumber to reclaim their lost empire, and the Orks wage war simply for the joy of it, their numbers beyond counting.

Yet humanity endures. The Space Marines, genetically enhanced super-soldiers created by the Emperor himself, are the Imperium’s greatest warriors. The Astra Militarum, the Imperial Guard, fights with sheer numbers and indomitable courage. The Adepta Sororitas bring religious fervour and righteous fury. The Adeptus Mechanicus tends the machines upon which civilisation depends. Together, these forces hold the line against the darkness, even as the Imperium rots from within under the weight of its own bureaucracy, corruption, and dogma.

This is the setting of Warhammer 40,000: a universe where hope is a luxury, heroes are forged in unimaginable suffering, and every victory is merely a brief respite before the next horror emerges. It is grimdark not for its own sake, but because it creates a backdrop against which even small acts of courage and defiance shine all the brighter.

The Age of Sigmar Setting in 60 Seconds

The Mortal Realms are a series of interconnected dimensions, each embodying a fundamental aspect of reality. Aqshy is the Realm of Fire, Ghyran the Realm of Life, Shyish the Realm of Death, and so on. These realms were shaped by the gods and populated by mortals who built civilisations of wonder and ambition during an era known as the Age of Myth.

That golden age ended when Chaos invaded. The Dark Gods sent their armies flooding into the Mortal Realms, corrupting everything they touched and bringing civilisation crashing down during the catastrophic Age of Chaos. For centuries, the forces of Chaos ruled unchallenged, and mortal societies were enslaved, destroyed, or driven into hiding.

Then Sigmar struck back. The God-King of Azyr, the Realm of Heavens, forged the Stormcast Eternals, immortal warriors reforged from the souls of mortal heroes, and launched a crusade to reclaim the Mortal Realms. This began the Age of Sigmar, an era of reconquest and rebuilding, but also of new conflicts. The forces of Death, led by the Great Necromancer Nagash, pursue their own agenda of turning all living things into undead servants. The forces of Destruction, including Orruks, Ogors, and Giants, rampage across the realms seeking battle and plunder. And Chaos, though pushed back, remains a constant and terrible threat.

Age of Sigmar is a setting of mythic scale and high fantasy, where gods walk among mortals, magic reshapes reality, and every battle has cosmic consequences. It combines classic fantasy elements with a unique cosmological framework that allows for extraordinary creativity in worldbuilding and storytelling.

Lore Reading Order

With so many novels, codexes, and sourcebooks available, knowing where to start reading can be a challenge. Here are our recommended starting points for both settings:

Warhammer 40,000

  • Core Rulebook: The lore sections of the current core rulebook provide an excellent overview of the setting, including the history of the Imperium, the major factions, and the current state of the galaxy.
  • Horus Heresy: Dan Abnett’s Horus Rising is the first novel in the Horus Heresy series, which tells the story of the Imperium’s civil war ten thousand years before the current setting. This series provides essential context for understanding the relationship between the Emperor, the Space Marines, and Chaos.
  • Gaunt’s Ghosts: Also by Dan Abnett, The Founding omnibus follows a regiment of Imperial Guard through the horrors of war in the 41st Millennium. These novels offer a ground-level perspective on the setting and are widely regarded as some of the best military science fiction ever written.
  • Eisenhorn: Dan Abnett’s Xenos begins the Eisenhorn trilogy, following an Imperial Inquisitor as he investigates threats to the Imperium. These novels are an excellent introduction to the more mysterious and conspiratorial aspects of the setting.
  • Faction Codexes: Your army’s codex contains detailed lore about your chosen faction, including history, notable characters, and background on individual units. Reading your codex deepens your connection to the models on your shelf.

Age of Sigmar

  • Core Rulebook: As with 40k, the Age of Sigmar core rulebook provides a comprehensive overview of the Mortal Realms, the Grand Alliances, and the ongoing narrative.
  • Realmgate Wars: The early Age of Sigmar novels chronicle the initial Stormcast Eternals campaign to reclaim the Mortal Realms from Chaos. These stories establish the core conflicts and characters of the setting.
  • Battletomes: Each faction’s battletome provides detailed lore about that army, including their history, culture, notable characters, and place within the broader narrative.
  • Dawnbringers: The Dawnbringers narrative arc tells the story of crusades to establish new cities in the Mortal Realms, providing a compelling ongoing storyline that connects to recent releases and rules updates.

How Lore Connects to the Tabletop

One of the most rewarding aspects of the Warhammer hobby is the connection between the narrative and the tabletop. Every unit in your army has a story behind it, every faction has a rich history that informs its playstyle and rules, and every battle you play can be interpreted as a chapter in your army’s ongoing narrative.

Games Workshop designs rules to reflect lore. Space Marines are tough and versatile because they are genetically enhanced super-soldiers. Orks are unpredictable because they are chaotic and impulsive by nature. Stormcast Eternals can be reforged after death, which is reflected in mechanics that allow them to return to battle. Understanding the lore behind your army’s rules deepens your appreciation of both the narrative and the gameplay.

Many players take this connection further by creating custom lore for their own armies. Writing a backstory for your Chapter, Warband, or Stormhost gives your army a unique identity and makes every game feel more personal. Some players keep campaign diaries that track their army’s victories, defeats, and narrative development over time, creating an ongoing story that enriches the hobby experience.

Narrative play formats explicitly encourage this lore-game connection, with campaign systems that allow battle results to influence the story. If your general falls in battle, perhaps they bear a scar in the next game. If you capture a territory, perhaps you gain access to new resources. These systems transform individual games into chapters of an epic saga that unfolds on your tabletop.

Fan Theories and Community Lore

The Warhammer community is home to a vibrant culture of fan theories, speculative lore, and community-driven narratives. Games Workshop’s settings are deliberately open-ended, leaving mysteries and ambiguities that invite speculation and interpretation. This has produced a rich ecosystem of fan content that ranges from well-reasoned theories about unrevealed plot points to elaborate homebrew narratives that expand the universe in creative directions.

Some of the most popular fan theories concern long-standing mysteries in the lore, such as the fate of the missing Space Marine Primarchs, the true nature of the Emperor’s plans, and the identity of figures only hinted at in official publications. These theories are debated enthusiastically in online forums and can add an extra layer of engagement to the hobby as you consider the evidence and form your own conclusions.

Community-created lore is equally valuable. Custom Chapters, warbands, and army backstories shared by hobbyists around the world demonstrate the extraordinary creativity of the community and provide inspiration for your own narrative projects. Many players find that creating lore for their armies is one of the most enjoyable aspects of the hobby, combining creative writing with visual storytelling through their painted miniatures.

We encourage all hobbyists to engage with the lore in whatever way brings them the most enjoyment, whether that means reading every novel in order, casually absorbing background from codexes and battletomes, creating elaborate backstories for their armies, or simply appreciating the aesthetic and thematic elements that make Warhammer’s settings so distinctive and enduring.

Frequently Asked Questions

Do I need to know the lore to play Warhammer?

Not at all. You can enjoy the tabletop game purely as a strategic exercise without engaging with the lore at all. However, many players find that understanding the background enhances their enjoyment of both the gaming and hobby aspects. The lore is there to enrich your experience, not as a prerequisite for participation.

Is the lore consistent across all publications?

Warhammer lore has evolved over decades and across hundreds of publications, so minor inconsistencies exist. Games Workshop treats the lore as in-universe accounts that may be biased, incomplete, or contradictory, much like real-world historical sources. This approach allows for creative flexibility and multiple valid interpretations of events.

Can I create my own lore for my army?

Absolutely, and we strongly encourage it. Creating custom lore for your army is one of the most rewarding aspects of the hobby. Your army’s backstory is yours to define, and it can be as detailed or as simple as you like. Many players name their characters, write battle reports as narrative accounts, and develop ongoing stories for their forces.

Where can I discuss lore with other fans?

Online communities dedicated to Warhammer lore are active and welcoming. Subreddits like r/40kLore and r/AoSLore are popular forums for discussion and speculation, while Discord servers and Facebook groups offer real-time conversation with fellow lore enthusiasts. Many local gaming groups also enjoy discussing background and narrative during and between games.
