Archaon the Everchosen — Lord of the End Times

Who Is Archaon the Everchosen?

Archaon the Everchosen is the most powerful mortal champion of Chaos in the Warhammer universe. He is the Three-Eyed King, the Lord of the End Times, and the supreme commander of the forces of Chaos Undivided. Unlike champions who serve a single Chaos God, Archaon has the favour of all four (Khorne, Tzeentch, Nurgle and Slaanesh) and wields their combined power as the Everchosen, the mortal champion destined to bring about the end of the world.

Archaon’s story is one of the most tragic in Warhammer lore. He was not born to Chaos or raised in the worship of dark gods. He was a devout warrior-priest of Sigmar who discovered a terrible prophecy about his own destiny and, in trying to defy it, fulfilled it completely. He was destroyed not by weakness but by the strength of his convictions.

In the Warhammer Fantasy setting, Archaon was the villain who ended the world itself, leading the forces of Chaos in the End Times that destroyed the Old World. In Age of Sigmar he continues as the supreme mortal champion of Chaos, leading the Slaves to Darkness in their war against Sigmar and the forces of Order. He is, in every meaningful sense, the setting’s ultimate mortal antagonist.

Origins: The Fall of a Sigmarite Templar

Archaon was born Diederick Kastner, and grew up to become a devout templar of Sigmar in the Empire. He was a man of genuine faith, dedicated to protecting the innocent and fighting the forces of darkness, and by every measure a loyal servant of Order.

Everything changed when Diederick came across an ancient book of prophecy, the Liber Caelestior, which described the coming of the Everchosen of Chaos. As he studied it, he realised with mounting horror that the prophecy described him: every sign and portent pointed to Diederick Kastner as the mortal destined to become the supreme champion of the Dark Gods and bring about the end of the world.

Diederick’s response was not to submit but to rage. He turned his fury on the gods themselves, both the Chaos Gods who sought to claim him and Sigmar, who he felt had abandoned him to this destiny. If Sigmar were truly a god of power and righteousness, he reasoned, such a prophecy could never exist. That it did proved Sigmar was either powerless or indifferent, and unworthy of worship either way.

This crisis of faith was the crack Chaos needed. Diederick was driven to it by despair, rage and the collapse of everything he believed in. He set out to fulfil the prophecy not out of devotion to the Dark Gods but out of spite towards all gods. That is what makes Archaon such a compelling villain: he is not a mindless servant of evil but a man who chose damnation as an act of defiance.

The Treasures of Chaos

To prove himself the Everchosen, Archaon had to claim six legendary treasures, each a test of his worthiness and each guarded by terrible dangers. The quest took him across the Old World and deep into the Chaos Wastes.

• The Armour of Morkar, worn by the first Everchosen, which marked Archaon as heir to every champion who had tried for the title before him.
• The Eye of Sheerian, a sorcerous gem that grants foresight. Set into his helm, it is the source of his title, the Three-Eyed King.
• The Steed of the Apocalypse, the daemonic horse Dorghar, which became his mount.
• The Slayer of Kings, a daemon sword holding the bound essence of the greater daemon U’zhul. The blade hungers for souls and gives Archaon tremendous power in combat.
• The Crown of Domination, which gave him authority over the warring hordes of Chaos.
• The Mark of Chaos Ascendant, the sign that all four Dark Gods had accepted him as their chosen.

With all six treasures gathered, Archaon was truly the Everchosen: the supreme mortal champion of Chaos Undivided, blessed by all four gods and wielding artefacts of apocalyptic power. Accounts of how and in what order he claimed them differ between older background material and the later novels.

The End Times

The End Times were the apocalyptic finale of the Warhammer Fantasy setting, and Archaon was their architect. Leading the largest Chaos invasion in the history of the Old World, he brought about the destruction of the world itself. This was not merely a military campaign but a cosmic event that ended one setting and began another.

Archaon’s invasion swept south from the Chaos Wastes in an unstoppable tide. Kislev fell. The Empire was torn apart by internal conflict and external assault. The forces of Order rallied again and again but were driven back, and key characters from across the setting met their ends.

The climax came at Middenheim, where Archaon fought Karl Franz, by then the vessel of Sigmar, as the world collapsed into Chaos. The world was destroyed, and from its remnants the Mortal Realms of Age of Sigmar were eventually born. Archaon achieved his goal of ending the world, but the consequences were not what anyone, including the Chaos Gods, had expected.

The End Times remain one of the most controversial events in Warhammer history. Many longtime fans were devastated by the loss of the Old World they had loved for decades; others welcomed a bold narrative choice that gave the setting genuine stakes. Either way, Archaon’s role as the destroyer of worlds cemented his status as one of the most important characters in Warhammer lore.

Archaon in Age of Sigmar

In Age of Sigmar, Archaon survived the destruction of the Old World and emerged as the supreme mortal champion of Chaos in the Mortal Realms. His power has only grown. Dorghar has become a huge, three-headed daemonic monster, and Archaon commands the allegiance of daemons and mortals alike.

Archaon leads the Slaves to Darkness, the mortal armies of Chaos Undivided, in their war against Sigmar and the forces of Order. His seat of power is the Varanspire, a fortress in the Eightpoints, the Chaos-held realm at the heart of the Mortal Realms. From there he directs campaigns of conquest across the realms, seeking to finish what he began in the Old World.

His relationship with the Chaos Gods remains complex. Archaon serves none of them exclusively, which is both his greatest strength and a source of constant tension. Each god would like to claim him, and Archaon plays them against each other, using their power without fully submitting to their will.

In the Age of Sigmar story, Archaon is the primary antagonist and a dark mirror of Sigmar himself. Both are beings of immense power who seek to shape the Mortal Realms to their vision, and their conflict is one of the central threads of the setting.

The Three-Eyed King

Archaon has many titles, but the Three-Eyed King is perhaps the most evocative. The third eye, the Eye of Sheerian set into his helm, gives him supernatural foresight, letting him glimpse the strands of fate and anticipate his enemies’ moves.

That foresight makes Archaon extremely hard to outmanoeuvre. Commanders who face him find their plans anticipated and countered, and it helps him keep his independence from any single divine patron.

From his throne in the Varanspire, the Three-Eyed King receives tribute from warlords and daemon princes, sends armies to conquer new territory and plots the final ruin of everything. He is patient, strategic and utterly implacable: a villain who combines overwhelming power with genuine intelligence and long-term vision.

Archaon on the Tabletop

On the tabletop, Archaon is one of the most powerful named characters in Age of Sigmar. His model, Archaon mounted on Dorghar, is a massive centrepiece that dominates the table both visually and in game terms, and he is fielded as part of a Slaves to Darkness army.

His rules reflect his status as the supreme champion of Chaos: formidable attacks from both Archaon and Dorghar’s three heads, great durability, and abilities that let him protect himself and drive the rest of the army on. He is very expensive, so building a list around him means committing a big share of your points to one model.

For his current warscroll, points and how he fits into Age of Sigmar 4th Edition armies, check the current Slaves to Darkness battletome and Games Workshop’s latest Battle Profiles, as both are updated regularly.

The model itself is one of the largest and most impressive in the Age of Sigmar range. Dorghar’s three heads, Archaon’s imposing armoured figure and the sheer size of the kit make it a challenging but rewarding painting project, the kind of centrepiece that defines a whole collection.

Archaon the Everchosen in the Novels

Black Library has told Archaon’s story in several novels. The main ones are:

• Archaon: Everchosen by Rob Sanders: Diederick Kastner’s fall from faith and his hunt for the treasures of Chaos.
• Archaon: Lord of Chaos by Rob Sanders: the sequel, following his rise to command the hordes of the north.
• The End Times series, especially The Lord of the End Times by Josh Reynolds, which covers his invasion and the end of the Old World.

Read the two Rob Sanders novels first for his origins, then the End Times books for his role in the destruction of the world. For more recommendations, see our list of the best Warhammer books.

Frequently Asked Questions

Was Archaon really a priest of Sigmar?

Yes. Archaon was born Diederick Kastner, a devout Sigmarite templar in the Empire. His fall to Chaos was triggered by the discovery of a prophecy that named him as the Everchosen, which destroyed his faith and drove him to embrace the Dark Gods out of spite and despair.

Did Archaon actually destroy the Old World?

Yes. During the End Times, Archaon led the forces of Chaos in a campaign that ended with the destruction of the Warhammer Fantasy world. This ended the Warhammer Fantasy Battles setting and led to Age of Sigmar and the Mortal Realms.

Which Chaos God does Archaon serve?

Archaon serves Chaos Undivided. He is favoured by all four Chaos Gods but loyal to none of them exclusively. This independence is both his greatest strength and a source of constant tension, as each god seeks to claim him for their own.

What is Dorghar?

Dorghar is Archaon’s daemonic mount, the Steed of the Apocalypse. Originally a dark steed, Dorghar has grown over the ages into a massive three-headed monster with heads representing three of the four Chaos Gods. It is one of the most powerful creatures in the Mortal Realms.

Is Archaon the most powerful character in Age of Sigmar?

Among mortal champions, yes. Archaon is the most powerful mortal servant of Chaos. However, he ranks below the Chaos Gods themselves, and god-like beings such as Sigmar and Nagash can match or exceed his power in different ways.

What does Everchosen mean in Warhammer?

The Everchosen is the single mortal champion favoured by all four Chaos Gods, prophesied to lead the forces of Chaos and end the world. Archaon was not the first to try for the title. Morkar, whose armour Archaon later claimed, was the first Everchosen, and others like Asavar Kul led great Chaos invasions before him. Archaon is the one who completed the prophecy during the End Times.

What happened at Archaon’s final battle in the Old World?

Archaon’s last battle in the Old World came during the End Times, when his armies besieged Middenheim and he fought Karl Franz, by then the vessel of Sigmar, as the world collapsed into Chaos. The Old World was destroyed. Archaon survived, and he later returned as the supreme mortal champion of Chaos in the Mortal Realms of Age of Sigmar.

What books tell Archaon’s story?

Rob Sanders’ two-part series is the main source: Archaon: Everchosen covers Diederick Kastner’s fall and his hunt for the treasures of Chaos, and Archaon: Lord of Chaos follows his rise to command the hordes of the north. For his role in the end of the world, read the End Times novels, especially The Lord of the End Times by Josh Reynolds.

What is the Varanspire?

The Varanspire is Archaon’s fortress and the seat of his power in Age of Sigmar. It stands in the Eightpoints, the Chaos-held realm at the centre of the Mortal Realms that links all eight realms through its Realmgates. From there the Three-Eyed King sends his armies across the realms, and the warbands of Warcry fight in its shadow for the chance to win his favour.
