Sigmar is the God-King who rules from the Celestial Realm of Azyr and created the Stormcast Eternals to reclaim the Mortal Realms from the forces of Chaos. He is a mortal man who became a god — first worshipped as a deity in the Old World, then reborn as the central figure of the Age of Sigmar setting. Sigmar is the founder of civilisation in the Mortal Realms, the forger of the greatest alliance of gods in history, and the architect of the counter-offensive that pushed back the tide of Chaos after centuries of darkness. He is, in many ways, the Warhammer equivalent of a mythic hero-king — a divine warrior who fights not for personal glory but for the survival of mortal civilisation.
Sigmar’s story is one of the longest and most complex in the Warhammer franchise, spanning two complete settings (Warhammer Fantasy and Age of Sigmar) and thousands of years of in-universe history. Understanding who Sigmar is — where he came from, what he has done, and what he represents — is essential to understanding the Age of Sigmar setting, because his decisions, his triumphs, and his failures have shaped every aspect of the Mortal Realms.

Where Did Sigmar Come From?
Sigmar began his existence as a mortal human in the World-That-Was — the original Warhammer Fantasy setting. He was born among the ancient tribes of what would become the Empire, the most powerful human nation in the old world. According to legend, Sigmar was the son of a tribal chieftain, and from birth he displayed extraordinary strength, courage, and leadership abilities that marked him as destined for greatness.
As a young warrior, Sigmar united the warring human tribes through a combination of military conquest, diplomatic alliance, and sheer force of personality. He forged an alliance with the dwarfs — the ancient and powerful mountain-dwelling race — after rescuing their High King from an orc ambush and receiving the legendary warhammer Ghal Maraz as a gift of gratitude. With Ghal Maraz in hand, Sigmar led the united human tribes to victory against the greenskin hordes at the Battle of Black Fire Pass, establishing the Empire of Man and being crowned its first Emperor.
After ruling the Empire for fifty years, Sigmar abdicated his throne and walked east into the wilderness, passing beyond the knowledge of men. He was never seen again in mortal form. In the centuries after his disappearance, a religious cult devoted to Sigmar grew within the Empire, eventually becoming the dominant faith of the nation. Sigmar was venerated as a god — the patron deity of the Empire, the protector of humanity, the wielder of Ghal Maraz. Whether Sigmar was truly divine during this period or simply a deified mortal is deliberately ambiguous in the old setting.
How Did Sigmar Survive the End Times?
During the End Times — the apocalyptic conclusion of the Warhammer Fantasy setting — the World-That-Was was destroyed by the forces of Chaos. As the world disintegrated, Sigmar’s divine essence clung to the metallic core of the world — a sphere of celestial metal called Mallus — and hurtled through the cosmic void.
Sigmar was found by Dracothion, the Great Celestial Drake — a being of immense cosmic power that existed between the realms. Dracothion recognised a kindred spirit in Sigmar and carried the God-King to the newly formed Realm of Azyr, the Celestial Realm. There, Sigmar found a new world — or rather, eight new worlds — waiting for him. The Mortal Realms had been born from the scattered Winds of Magic, and Sigmar saw in them an opportunity to build something greater than the world he had lost.
In Azyr, Sigmar’s divine nature was fully realised. Whether he had been a true god in the old world or merely a deified mortal, in the Mortal Realms there was no ambiguity — Sigmar was a god, with the power to shape reality, forge divine weapons, and create new forms of life. He was not the most powerful god in the Mortal Realms (Nagash and Gorkamorka could both claim comparable or greater raw power in their respective domains), but he was arguably the most purposeful — driven by a clear vision of what he wanted the Mortal Realms to become.
What Did Sigmar Do During the Age of Myth?
The Age of Myth was Sigmar’s golden era — a period of exploration, alliance-building, and civilisation-founding that lasted for centuries. During this time, Sigmar travelled the Mortal Realms, discovering the other gods who had survived the destruction of the old world and forging alliances with them.
The Pantheon of Order was Sigmar’s greatest diplomatic achievement — an alliance of gods that included Nagash (God of Death), Alarielle (Goddess of Life), Gorkamorka (God of Destruction), Grungni (God of the Forge), Teclis and Tyrion (Gods of Light), and Malerion (God of Shadow). This was an extraordinary coalition, bringing together deities whose natures and agendas were fundamentally different and often contradictory. That Sigmar managed to hold this alliance together for as long as he did is a testament to his diplomatic skill and personal charisma.
During the Age of Myth, mortal civilisations flourished across the Mortal Realms. Cities were built, trade routes were established, knowledge was accumulated, and culture thrived. This was the closest the Mortal Realms have ever come to a period of genuine peace and prosperity, and it was largely Sigmar’s achievement — his vision, his alliances, and his protection made it possible.
But the Age of Myth could not last. The Chaos Gods found the Mortal Realms, and their invasion shattered everything Sigmar had built.
What Happened During the Age of Chaos?
The Age of Chaos was the darkest period in the history of the Mortal Realms. The Chaos Gods launched a massive invasion, pouring daemons, beastmen, and mortal followers into the realms in a tide of destruction that overwhelmed realm after realm. The Pantheon of Order collapsed — Nagash withdrew to Shyish to pursue his own agenda, Gorkamorka was defeated and splintered, Alarielle retreated into hiding in Ghyran, and the other gods scattered to defend their own domains.
Sigmar fought against Chaos for as long as he could, but even a god could not hold back the full might of four Chaos Gods simultaneously. Eventually, Sigmar made the most controversial decision of his divine career: he retreated. He sealed the Gates of Azyr — the Realmgates connecting the Celestial Realm to the other realms — and withdrew behind them, abandoning the other seven realms to Chaos.
This decision is the defining moral question of Sigmar’s character. From a strategic perspective, it was arguably the right choice — by preserving Azyr, Sigmar ensured that at least one realm remained free from Chaos, providing a base from which a counter-offensive could eventually be launched. From a moral perspective, it was an act of abandonment — Sigmar left billions of mortal people to suffer under Chaos rule, condemning entire civilisations to centuries of torment. The people of the other realms have never fully forgiven him for this, and the tension between Sigmar’s strategic pragmatism and his moral responsibility is one of the central themes of the Age of Sigmar narrative.
How Did Sigmar Create the Stormcast Eternals?
During the centuries he spent behind the sealed Gates of Azyr, Sigmar was not idle. He was planning his counter-attack, and at the centre of that plan was his most ambitious creation: the Stormcast Eternals.
Working with Grungni, the duardin god of the forge, Sigmar developed a process for creating superhuman warriors infused with divine lightning. The process took mortal heroes — the bravest, most virtuous, most capable warriors from across the Mortal Realms — and reforged them in the celestial forges of Azyr. Their mortal bodies were destroyed and rebuilt, enhanced with divine power, and clad in sigmarite armour (forged from the celestial metal of Mallus, the core of the old world). The result was the Stormcast Eternals — warriors who were more than human, each one a living conduit for Sigmar’s divine power.
The Stormcast Eternals are Sigmar’s answer to the Space Marines of Warhammer 40,000 — elite superhuman warriors who serve as the backbone of the setting’s “good” faction. However, the Stormcast have a crucial difference from Space Marines: they can be reforged. When a Stormcast Eternal dies, their soul is caught by Sigmar’s divine lightning and returned to Azyr, where they are reforged and sent back to battle. This makes them, in theory, immortal — but each reforging takes a toll, eroding the warrior’s memories, personality, and humanity. A Stormcast who has been reforged many times becomes cold, distant, and mechanical — more weapon than person. This slow loss of humanity is the central tragedy of the Stormcast Eternals, and it mirrors the broader theme of Age of Sigmar: that the fight against Chaos exacts a terrible cost, even from those who win.
What Is Sigmar Like as a Character?
Sigmar is a complex character who defies easy categorisation. He is a god of war and civilisation, of strength and wisdom, of pragmatism and idealism. He is capable of great nobility — he genuinely cares about the mortal peoples of the realms and has sacrificed enormously to protect them. He is also capable of great ruthlessness — he is willing to make terrible decisions (like sealing the Gates of Azyr) when he believes the greater good demands it.
Sigmar’s defining characteristic is his sense of responsibility. He does not view his divine power as a right or a privilege — he views it as an obligation. He did not ask to be a god, but since he is one, he feels compelled to use his power to protect those who cannot protect themselves. This sense of duty drives everything he does, from the creation of the Stormcast Eternals to his ongoing war against Chaos.
However, Sigmar is not infallible. He makes mistakes, misjudges situations, and sometimes lets his emotions override his judgement. His relationship with Nagash is a case in point — Sigmar has repeatedly attempted to ally with the God of Death, despite abundant evidence that Nagash is untrustworthy and has his own agenda. Sigmar persists in these attempts because he believes the threat of Chaos is too great to face without the Death God’s power — but his willingness to overlook Nagash’s nature has led to disastrous consequences more than once.
Sigmar is also isolated by his divinity. He sits on his throne in Azyr, directing the war effort through intermediaries and divine visions, but he rarely interacts directly with mortal people. This distance — between the god and the people he is trying to save — creates a disconnection that his enemies exploit. The people of the realms worship Sigmar, but many of them also resent him — for the years he spent behind sealed gates while they suffered, for the Stormcast Eternals who protect them but are not quite human, and for the wars fought in his name that devastate their lands.
What Is Sigmar’s Relationship With Other Gods?
Sigmar’s relationships with the other gods of the Mortal Realms are defined by a combination of mutual need and mutual suspicion.
Nagash is Sigmar’s most important and most difficult relationship. The God of Death and the God-King are natural enemies (Sigmar wants to protect the living, Nagash wants them all dead), but the threat of Chaos has forced them into uneasy alliances on multiple occasions. These alliances have always ended badly — Nagash inevitably betrays Sigmar when it suits him, and Sigmar is eventually forced to fight the Death God alongside Chaos. Their rivalry is one of the central conflicts of the setting.
Alarielle resents Sigmar for abandoning Ghyran during the Age of Chaos, forcing her to fight Nurgle’s forces alone. Their alliance has been restored but remains strained by this history of perceived betrayal.
Gorkamorka was an ally during the Age of Myth but is too chaotic and destructive to be a reliable partner. The orruk god fights Chaos, Order, and Death with equal enthusiasm, and Sigmar has largely given up trying to incorporate Gorkamorka into his plans.
Grungni is Sigmar’s most reliable ally — the duardin forge-god helped create the Stormcast Eternals and continues to support Sigmar’s war effort. Their relationship is the closest thing Sigmar has to a genuine friendship among the gods.
Frequently Asked Questions
Is Sigmar the Emperor from Warhammer 40k?
No. Despite superficial similarities (both are powerful human leaders who founded empires and are associated with lightning imagery), Sigmar and the Emperor of Mankind are separate characters in separate settings. Warhammer 40,000 and Age of Sigmar share some thematic DNA but are not set in the same universe. The Emperor is a psychic being more than 40,000 years old; Sigmar is a barbarian king who became a god through worship and divine apotheosis.
Can Sigmar fight in battle himself?
Sigmar is physically capable of fighting and has done so at critical moments in the setting’s history. However, in the current Age of Sigmar narrative, Sigmar rarely takes the field personally, preferring to direct the war effort from Azyr. The reasons for this are partly narrative (the setting would be less interesting if a god solved every problem personally) and partly strategic (Sigmar’s presence is needed in Azyr to maintain the reforging process and coordinate the war across all eight realms).
Does Sigmar have a model on the tabletop?
As of the current edition, Sigmar does not have an official tabletop model in Age of Sigmar. He is represented on the battlefield through his Stormcast Eternals and through named characters who serve as his champions. Games Workshop has occasionally hinted at the possibility of a Sigmar model, but as of now, the God-King remains an off-table presence.
What is Ghal Maraz?
Ghal Maraz (meaning “Skull Splitter” in the dwarf tongue) is Sigmar’s legendary warhammer — a weapon of immense divine power that has been his signature armament since his mortal days. It was gifted to him by the dwarf High King Kurgan Ironbeard and has been lost and recovered several times throughout Sigmar’s long history. In Age of Sigmar, Ghal Maraz is one of the most powerful weapons in the Mortal Realms, capable of banishing daemons, shattering magical wards, and striking with the force of a thunderbolt.
Why is the setting called “Age of Sigmar”?
The setting is named after the current era in the Mortal Realms’ history — the age that began when Sigmar unsealed the Gates of Azyr and sent the Stormcast Eternals to reclaim the realms from Chaos. The Age of Sigmar follows the Age of Myth and the Age of Chaos, and it represents the current chapter in the Mortal Realms’ story: a time of reconquest, rebuilding, and ongoing conflict. The name also reflects Sigmar’s central importance to the setting — he is the driving force behind the narrative, even when he is not physically present on the battlefield.
How did Sigmar become a god?
In the old Warhammer world, Sigmar founded the Empire, ruled it for fifty years, then abdicated and walked east, never to be seen again. The faith that grew up around him made him the Empire’s patron god. When the world ended, his essence survived clinging to Mallus. In the Mortal Realms his godhood is no longer in question.
Where does Sigmar live?
Sigmar rules from Sigmaron, his great palace in the heavens of Azyr, the Celestial Realm. Below it lies Azyrheim, the first and greatest of his cities. The Stormcast Eternals are reforged in Azyr, and the Gates of Azyr link it to the other Mortal Realms. Sigmar sealed those gates during the Age of Chaos and reopened them to begin the Age of Sigmar.
Why is Sigmar linked to storms and lightning?
Lightning is Sigmar’s signature power in the Mortal Realms. His Stormcast Eternals ride bolts of celestial lightning down to the battlefield, and when they fall, their souls return to Azyr on the same lightning to be reforged. That is why Sigmar is often called a storm god and why his armies take their name from storms.
