Cypher — The Fallen Angel

Who Is Cypher?

Cypher is the most enigmatic and mysterious figure in all of Warhammer 40,000. He is a member of the Fallen — the Dark Angels Space Marines who turned traitor during the Horus Heresy — and yet his actions often seem to serve the Imperium’s interests. He carries an ancient sword that he is never seen to draw, fights with a bolt pistol and a plasma pistol with preternatural skill, and appears and disappears across the galaxy with no pattern or purpose that anyone can discern. He has been hunted by the Dark Angels for ten thousand years, and they have never caught him. Not for want of trying.

The title “Cypher” is itself a mystery. It may be a name, a rank, or a code designation. One popular theory holds it refers not to a single individual but to a role — that different beings have carried the title “Cypher” across the millennia, each one taking up the mantle and the mysterious sword when the previous bearer falls. This theory would explain how Cypher can appear in multiple locations across the galaxy in timeframes that seem impossible for a single being.

What makes Cypher truly fascinating is the impossibility of determining his loyalty. He has fought alongside Imperial forces, appearing at critical moments to turn the tide of battles. He has also been seen in the company of Chaos warbands, heretics and other Fallen when it suited his purposes. He seems to serve no master but his own inscrutable agenda, and that agenda — whatever it is — has proven impossible for anyone to unravel.

The Most Wanted Being in the Imperium

Within the Dark Angels Chapter and its many successors — collectively known as the Unforgiven — Cypher is the single most wanted individual in existence. The capture or destruction of Cypher is the paramount objective of the Inner Circle, the secretive ruling body that controls the Dark Angels’ hidden agenda. The Chapter will bend almost any resource or alliance towards the hunt.

The reason for this obsessive pursuit is bound up in the Dark Angels’ greatest shame: the existence of the Fallen. During the Horus Heresy, a significant portion of the Dark Angels Legion turned traitor under the leadership of Luther, Lion El’Jonson’s second-in-command. This betrayal shattered the Legion’s homeworld of Caliban and scattered the traitors across time and space through a Warp storm. The Dark Angels have spent the subsequent ten thousand years hunting down these Fallen in absolute secrecy, terrified that the wider Imperium will learn of their shame.

Cypher is the most prominent and most elusive of all the Fallen. His continued freedom is a constant reminder of the Dark Angels’ failure to resolve their ancient disgrace. A confirmed sighting of Cypher can send companies, or even whole successor Chapters, away from their assigned missions to chase him down — a habit that has not gone unnoticed by other Imperial commanders, though the true reason stays hidden.

The Fallen

The Fallen are the Dark Angels who turned traitor during the destruction of Caliban at the end of the Horus Heresy. When the Warp storm consumed Caliban, it scattered the Fallen across both space and time. Some emerged in different sectors of the galaxy. Others emerged in different eras entirely — Fallen have appeared in periods ranging from immediately after the Heresy to the present day, having experienced no subjective time during their journey through the Warp.

Not all of the Fallen are equal in their treachery. Some were willing traitors who followed Luther into rebellion against Lion El’Jonson with full knowledge and intent. Others were confused, coerced, or simply caught up in events beyond their control. Some have spent the millennia since their scattering trying to atone for their betrayal, living quiet lives on remote worlds and seeking redemption. Others have embraced Chaos fully and become warband leaders and daemon-worshippers.

Cypher’s relationship with the broader Fallen is unclear. He does not appear to lead them in any organized fashion, nor does he seem to share the goals of those who have fully embraced Chaos. He has been observed interacting with other Fallen on occasion, sometimes apparently guiding or directing them, but the purpose of these interactions is never clear. Some within the Dark Angels suspect that Cypher is actively working to gather the Fallen for his own purposes — but what those purposes might be remains anyone’s guess.

The Dark Angels’ treatment of captured Fallen is harsh. Those who are taken alive are subjected to interrogation by the Chaplains of the Chapter — the Interrogator-Chaplains — who use every means at their disposal to extract confessions and information. The goal is repentance: a Fallen who confesses is granted the Emperor’s mercy, which in practice usually means a swift death. Those who refuse face far worse.

The Lion Sword

Perhaps the most mysterious aspect of Cypher is the ancient sword he carries but never draws. This weapon is believed by many to be the Lion Sword — the personal blade of Primarch Lion El’Jonson himself. If this is true, the implications are staggering. It would mean that Cypher, a Fallen traitor, carries one of the most sacred relics of the Dark Angels Chapter — a weapon forged for a Primarch and imbued with power beyond mortal comprehension.

In every account of Cypher in battle, the sword stays sheathed on his back. He fights with his two pistols instead, a bolt pistol and a plasma pistol, wielding them with a speed and accuracy that borders on the supernatural.

The question of why Cypher never draws the sword is one of the great mysteries of Warhammer 40,000. Multiple theories exist. Some believe the sword is broken and Cypher means to bring it before the Emperor on Terra. Others believe that the sword is a key to some greater mystery, and that drawing it would trigger an event of enormous significance. Still others believe that Cypher is bound by an oath or a curse that prevents him from drawing the blade until specific conditions are met.

Whatever the truth, the sword seems central to Cypher’s agenda, and most fans agree that understanding it would be the key to understanding him.

The Dark Angels’ Obsession

The Dark Angels have pursued Cypher with a fervor that borders on madness. The Chapter’s entire hidden structure — the Inner Circle, the Deathwing, the Ravenwing — exists in part to hunt the Fallen, and Cypher is the Fallen who matters most.

This obsession comes at a cost. Dark Angels forces have been known to abandon allies or withdraw from engagements without explanation when word of the Fallen reaches them. Those withdrawals have earned the Chapter a reputation for unreliability among some Imperial commanders, which the Dark Angels accept, because to them the hunt matters more than any single campaign.

The Ravenwing — the Dark Angels’ fast attack specialists — serve as the primary pursuit force, using their speed to run down leads and corner suspected Fallen. The Deathwing — the elite Terminator company — serves as the hammer that strikes once a Fallen has been located. Between them they have caught many Fallen, but never Cypher for long.

Whether the Dark Angels would actually benefit from capturing Cypher is an open question. His knowledge of the Chapter’s secrets could be devastating if revealed to the wider Imperium. His sword, if it is indeed the Lion Sword, would be a priceless relic. But the pursuit itself has become so central to the Dark Angels’ identity that some observers wonder if the Chapter could exist without it — whether the hunt has become the purpose rather than the means to an end.

Cypher’s True Loyalty — Unknown

The fundamental question about Cypher — the question that drives every other mystery surrounding him — is simple: whose side is he on? After ten thousand years, the answer remains: no one knows.

The case for Cypher being a secret loyalist is strong. He has appeared at critical moments to save Imperial forces from destruction, and he has fought against the servants of Chaos. His apparent desire to reach Terra and the Golden Throne could be interpreted as a mission of salvation — perhaps he seeks to present the Lion Sword to the Emperor or to deliver some crucial message. If Cypher is loyal, he may be the greatest and most selfless servant the Emperor has ever had, enduring ten thousand years of persecution for a mission only he understands.

The case for Cypher being a traitor is just as compelling. He has been seen alongside Chaos forces, and he has killed Imperial servants who stood in his way. His association with the Fallen — many of whom are confirmed traitors — suggests that his loyalties lie with the dark side of the Dark Angels’ legacy. If Cypher is a traitor, he may be pursuing an agenda of ultimate betrayal — seeking to reach Terra not to save the Emperor but to strike at Him when the Imperium is most vulnerable.

The truth may be more complex than either interpretation allows. Cypher may be loyal to neither the Imperium nor Chaos but to his own vision of what the galaxy should be. He may be an agent of a power that transcends the simple loyalist-traitor binary. Or he may simply be insane — a ten-thousand-year-old warrior whose original purpose has been lost to time and madness, leaving only habits and reflexes where motivation once existed.

Appearing Before Guilliman

One of the most dramatic moments in Cypher’s long history came during the Gathering Storm narrative, when he appeared to the newly resurrected Primarch Roboute Guilliman. Cypher and a band of Fallen joined Guilliman’s forces on their desperate journey to Terra and fought alongside them.

This alliance sent shockwaves through the Dark Angels Chapter and the Unforgiven successors. The idea that a Primarch — even one from a different Legion — would willingly ally with the most wanted Fallen in the galaxy was deeply unsettling. Guilliman, however, proved characteristically pragmatic, accepting Cypher’s aid without endorsing his cause.

The alliance ended badly for Cypher. Once on Terra he was taken into custody and imprisoned within the Imperial Palace, so his apparent goal of reaching the Golden Throne — whatever its purpose — was thwarted at the last moment. In typical fashion, later accounts have him free and at large in the galaxy once more, and how he got out is never fully explained.

The implications of this episode continue to reverberate. Cypher demonstrated that his desire to reach the Emperor on the Golden Throne is genuine and deeply important to him. His willingness to ally with a Primarch and fight his way to Terra suggests that whatever drives him is worth any sacrifice. The question remains: what would Cypher have done if he had reached the Golden Throne?

Cypher on the Tabletop

On the tabletop, Cypher is a unique character model whose rules reflect his skill with pistols rather than his sword. He is primarily a shooting character, using his bolt pistol and plasma pistol, and his close combat ability has deliberately been kept modest because he never draws the blade.

Which armies can take him has changed between editions, reflecting his ambiguous loyalties: at different times he has been available to Imperial and Chaos armies, usually alongside the Fallen. For Warhammer 40,000 11th Edition, check the current codex and the Munitorum Field Manual for which factions can include him, his points and his exact abilities. If you want to know how characters like him join other units in 11th Edition, see our guide to Leader rules in 40k 11th Edition.

The hooded figure with two pistols and a sheathed sword on his back is one of the most recognisable silhouettes in the Warhammer 40,000 range. He is a relatively simple model to build and paint, but the character he represents is anything but simple.

Frequently Asked Questions

Is Cypher loyal to the Emperor?

No one knows for certain. Cypher has acted in ways that support both loyalist and traitor interpretations. His true allegiance is one of the deliberately unresolved mysteries of Warhammer 40,000, and Games Workshop has intentionally kept his loyalties ambiguous.

Why doesn’t Cypher draw his sword?

The reason is unknown. The sword is believed to be the Lion Sword of Primarch Lion El’Jonson, and theories range from it being broken and needing reforging to Cypher being bound by an oath not to draw it until specific conditions are met. This is another of the character’s central mysteries.

Has Cypher ever been captured?

Yes. The best-known occasion came after the Gathering Storm, when he was imprisoned within the Imperial Palace on Terra after travelling there with Roboute Guilliman. As ever with Cypher, he did not stay a prisoner, and how he got free is never fully explained.

What is Cypher’s real name?

Unknown. “Cypher” may be a title, a code name, or a designation rather than a personal name. Some theories suggest that “Cypher” is a role rather than an individual, and that multiple beings have carried the title across the millennia.

Why do the Dark Angels hunt Cypher so obsessively?

Cypher is the most prominent and elusive of the Fallen — the Dark Angels who turned traitor during the Horus Heresy. The Dark Angels’ deepest shame is the existence of these traitors within their ranks, and they have spent ten thousand years hunting them in secret. Cypher’s continued freedom is a constant reminder of their failure to resolve this ancient disgrace.

Who are the Unforgiven in Warhammer 40k?

The Unforgiven are not a single character but the Dark Angels and their successor Chapters together, such as the Angels of Absolution and Angels of Vengeance. The name reflects the shame they carry over the Fallen, whose betrayal they hunt in secret. Cypher, the most wanted of the Fallen, is the figure the Unforgiven pursue above all others.

Who is Luther in the Dark Angels?

Luther was Lion El’Jonson’s second-in-command and closest friend on Caliban, who turned against him at the end of the Horus Heresy. His betrayal split the Legion, destroyed Caliban and scattered the Fallen through time and space. For ten thousand years he was held deep within the Rock, the Dark Angels’ fortress-monastery, a secret guarded by the Inner Circle.
