The Void Tridents is a Loyalist Space Marine Chapter comprised entirely of Primaris Space Marines created from the lineage of the Ultramarines and raised during the Ultima Founding of 999.M41. Recruited from the Ocean World of Talassar in the Realm of Ultramar, the Void Tridents follow the naval traditions of the Ultramaran empire.
They are experts in starship boarding actions and ship-to-ship warfare, though under the command of Lord Commodore Theodro Vethrus, they have also proven themselves to be expert at planetary assaults.
For ten 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...
- Indomitus Crusade (ca. 999.M41-111.M42) - Under its Chapter Master, Lord Commodore Theodro Vethrus, the Void Tridents were the first Chapter to cross the Nachmund Gauntlet from the world of Sangua Terra to Vigilus. The Void Tridents outran the Daemon fleet of Warpsmith Tzungdan as they cut a path past Omis-Prion. Had it not been for the distress signals their Librarian picked up regarding Vigilus, they would have likely been able to outmanoeuvre Tzungdan and destroy his base. In the end, they diverted to Vigilus and fought a series of board-and-slay missions against the Ork cordon there instead.
Notable Void Tridents
- Lord Commodore Theodro Vethrus - Theodro Vethrus is the first and current Chapter Master, or "Lord Commodore," of the Void Tridents.
The Void Tridents wear the dark blue of the southern Talassarian oceans echoed in their Mark X Power Armour. The Aquila or Imperialis on the chest is copper, as is the shoulder pauldron trim and the helm. The inset of the right shoulder pauldron is white. The Chapter's colours are reminiscent of the strong naval traditions of its homeworld of Talassar -- the blue represents the sea, while the white and copper are both maritime colours, the white of a ship's sails and the copper of its fittings. Chapter markings and unit designations are red. The red squad specialty symbol (Tactical, Devastator, Assault or Veteran) is displayed on the right shoulder pauldron, while the inset of the left shoulder pauldron is red and proudly displays the Chapter's iconography. The company number is displayed as a red Roman numeral on the left poleyn (knee guard) and the squad number as a black Roman numeral placed in the centre of the squad specialty symbol on the right shoulder pauldron.
The Void Tridents' Chapter badge is a red trident pointed upward, centred on a field of white.
