The Sons of the Phoenix is a Loyalist Space Marine Chapter comprised entirely of Primaris Space Marines created from the lineage of the Imperial Fists and raised during the Ultima Founding of 999.M41. Faithful to the Emperor and ritualistic in their battle cant, the Sons of the Phoenix pride themselves on plunging into the flames of battle.

They are constantly on crusade, which are led by their Chaplains. Their crusades are so impressive in spectacle they pave the way for the Imperial Creed to spread across the galaxy, and hence are followed by a great many holy men and women.

Chapter History

Sons of the Phoenix Chapter Colour Scheme, 5th Company, unknown Intercessor

For ten Terran millennia, Archmagos Dominus Belisarius Cawl has been working on a task set for him by the Primarch Roboute Guilliman before he was mortally wounded by the Daemon Primarch Fulgrim in the days after the Horus Heresy: a new legion of transhuman warriors. Developed on orders from Guilliman 100 standard centuries past, Primaris Space Marines were diligently developed and perfected by the Priesthood of Mars during the long intervening millennia.

As an optimist, but never a fool, Guilliman learned from the mistakes of the Horus Heresy, and he foresaw that the Forces of Chaos would never relent in their aim to bring the Imperium low. He anticipated that devastating times would once again engulf the galaxy and knew that warriors resilient enough to stand against them would be needed as never before. That time has surely come. Now, as the Imperium of Man is poised on the brink of annihilation at the hands of Chaos, his task is at last complete.

The Primaris Space Marine is a new breed of hero for this, the darkest age in the Imperium's history. These new warriors are the next step in the evolution of the Emperor's Angels of Death -- genetically altered from their brethren to be bigger, stronger and faster -- timely reinforcements for the Imperium's armies as their enemies close in for the kill in the wake of Abaddon the Despoiler's 13th Black Crusade and the birth of the Great Rift dividing the Imperium in two.

To aid them in battle, these gene-forged warriors are equipped with new arms and armour forged on Mars itself, such as the Mark X Tacticus Pattern Power Armour worn by the Primaris Space Marine Intercessors, which combines the most effective elements of ancestral Horus Heresy patterns of battle-plate with more recent developments in Power Armour technology; the Mark II Cawl Pattern Bolter, the archetypal firearm of the Adeptus Astartes, now re-engineered, re-crafted and perfected, and Redemptor Dreadnoughts.

At the dawn of the Indomitus Crusade to retake the Imperium from the advancing armies of Chaos and xenos alike, Lord Commander of the Imperium Roboute Guilliman has gathered his new armada, along with elements of the Adeptus Custodes, a small contingent of the Silent Sisterhood and a vast war host of Primaris Space Marines as he fights to liberate the scattered bastions of the Imperium. Some, Guilliman has forged into new Space Marine Chapters, whole brotherhoods comprised only of these new transhuman warriors. Others he has offered to the existing Space Marine Chapters. Many Chapter Masters have welcomed their Primaris brethren into their ranks, accepting the new reinforcements gladly. Others, though, view these new creations with suspicion or outright hostility, claiming that the Emperor's work should never have been meddled with by mere mortals.

Though they are a step removed from their brothers, the Primaris Space Marines still bear the gene-seed of their Primarchs, and some dissenting voices worry how this new type of warrior will react with the known genetic quirks and flaws of some of the more unusual Chapters, such as the Blood Angels and the Space Wolves. Though the Primaris Space Marines offer new hope to a besieged Imperium, the future remains a dark and uncertain place...

Notable Campaigns

  • War of Beasts (Unknown Date.M42) - The Sons of the Phoenix eagerly answered the call to aid the vitally important Imperial world of Vigilus. Their presence in Hyperia Hivesprawl had a galvanising effect on the Vigilant Guard and Adepta Sororitas who had long anticipated their coming. Though the Sons of the Phoenix are a relatively new addition to the armies of the Emperor, during the Wars of Antipathy they won a reputation for levelling spectacular firestorms against the foe -- and for the fact that they would fight on through those flames without hesitation.

Chapter Appearance

Chapter Colours

The Sons of the Phoenix wear off-white Mark X Power Armour to display their purity. The Aquila or Imperialis on the chest is gold, as is the shoulder pauldron trim. The inset of the right shoulder pauldron is purple as is the right gauntlet and left poleyn (knee guard). Chapter markings and unit designations are gold.

The gold squad specialty symbol is displayed on the right shoulder pauldron, while the inset of the left shoulder pauldron is white and proudly displays the Chapter's iconography.

The company number is displayed as a golden Roman numeral on the left poleyn or placed in the centre of the squad specialty symbol on the right shoulder pauldron. An additional, smaller specialty symbol is displayed next to the company number on the left poleyn, which designates a company's specialty (Tactical, Assault, Devastator or Reserve).

The standard Sons of the Phoenix helm is white. Unusually, the Sons of the Phoenix utilise the opposite colours to distinguish their Sergeants and Lieutenants. A Sons of the Phoenix Sergeant is designated by a white helm with a single red vertical stripe, while a Lieutenant is designated with a red helm.

Chapter Badge

The Sons of the Phoenix's Chapter badge is a stylised black helm to which a star of the same colour is adjacent. A stylised black wing protrudes from the helm's bottom as black electric lightning bolts rise from the top.
