Horus Heresy

Sicaran Omega Tank

The Sicaran Omega Finis Virtutis (End of Valor) serves as the 121st’s answer to heavily armored infantry and veteran formations. Its plasma burn array is used to break concentrations of Terminators and Legion elites that would otherwise require a costly infantry assault, while the speed of the Sicaran chassis allows it to redeploy quickly wherever resistance is strongest. Vehicularis Legionaries Loran prioritizes veteran formations, command cadres, and other elite infantry regardless of easier targets nearby. Corda has become adept at identifying officers and specialists through magnified optics, then placing the Omega’s fire where it will consume as much of their…

Predator Support Tanks with Conversion Beamers

Aromored Support: Predator Support Tank Longa Manus The Predator Longa Manus (Long Hand) earned its name during the Scouring, where its conversion beam cannon proved particularly effective against Iron Warriors strongpoints. Its crews learned to fight at extreme range, patiently seeking firing lanes before reducing bunkers, gun emplacements, and armored vehicles with precisely placed shots. Vehicularis Legionaries The crew of the Longa Manus bicker some, but they get the job done. Coren is notorious for refusing marginal shots, while Maro continually adjusts their position to extend the range of an engagement, sometimes throwing off Coren’s shots. Other crews joke that the three…

Dreadnought Drop Pod

The Dreadnought Drop Pod Ferrum Caelum (Iron Sky), attached to the 2nd Company’s orbital assault complement, has delivered honored dreadnoughts into combat across compliance actions, void assaults, and planetary insertions since the latter years of the Great Crusade. Its guidance cogitator and retro-thruster assemblies have undergone repeated refurbishment, but its original armored shell remains in service, bearing the accumulated impact scars of decades of operational deployments. Wargear

Veteran Tactical Squad Helikon

Among the veterans of the 2nd Company, Veteran Tactical Squad Helikon has earned a reputation for reducing even the most numerous of enemy forces through relentless thermal energy weapon assault. They use their volkite chargers and culverins paired with perfect timing, positioning, and absolute confidence in the skills of their squadmates.  Squad Legionaries Wargear Kitbash

Forge Lord: Maris Torvane

Forge Lord Maris Torvane permits a variety of approaches to workings of the Machine God in her ranks. Purists, innovators, improvisers — all have their place, so long as the Legion endures. Her genius lies not in perfection, but in knowing which flaws to allow. She studies her Techmarines as carefully as they study their machines, weighing their tendencies against the demands of war. Where others might rigidly enforce unity, Thorne cultivates tension — and in that friction, she forges innovation and resilience that no single doctrine could achieve. Wargear Kitbash

Techmarine Covenant: Livia Rhune

Techmarine Livia Rhune works best when things are already broken. She thrives in the chaos of the battlefield, rebuilding weapons and armor under fire with whatever she can salvage. Her repairs are ugly, temporary — and uncannily effective. Wargear Kitbash

Rapier Battery Squad Davion

Sergeant Davion’s Rapier Battery Squad specializes in battlefield control, favoring quad launchers for their versatility and swapping over to laser destroyers when the mission calls for engaging heavier targets. Phosphex rounds are held in reserve, a final answer to threats that cannot be contained by more precise applications of force or traditional means. Squad Legionaries Wargear

Sicaran Arcus Tank

The Sicaran Arcus Tank Tertius Bellum (Third War) was assembled from the remains of three destroyed vehicles in the aftermath of the Betrayal. Its machine-spirit is temperamental, and its armor plates still carry scorch patterns from the surface of Calth itself. The 121st keeps it in the line not for sentiment but because despite its quirks, it always does what needs to be done. When command needs a target reduced to rubble without delay or ceremony, Tertius Bellum is called forward. Vehicularis Legionaries Dane and Kell are known for the shortest engagement cycles in the company. They operate on minimal…

Veteran Assault Squad Ardentis

When the 121st rebuilt after Calth, Legate Presca said, “The Legion still breathes.” Veteran Assault Squad Ardentis was that breath made flesh. Drawn from Inductii who survived the earliest retaliations of the Shadow Wars, they carry themselves with quiet defiance, as if to prove the XIIIth never truly broke. Every strike they make is an echo of that vow—to keep breathing, no matter how the galaxy burns. Squad Legionaries Wargear Kitbash

Techmarine Covenant: Corvina Cauris

Techmarine Corvina Cauris calls her methods “practical deviations.” She never breaks from equipment regulations, she just interprets its margins. Her tools are modified for efficiency, her calibrations half a hair from standard, her results flawless. The Magi grumble; Legate Presca does not. Every boltgun she’s serviced fires smoother, every reactor she’s tuned runs longer. Wargear Kitbash

Tarantula Sentry Turrets: Hyperios Anti-Air Missile

The Hyperios-pattern Tarantula integrates an automated tracking suite calibrated to the airframes of known traitor Legions. Its anti-air missiles are capable of independent target lock or full integration with command auspex relays, forming a mobile, automated defensive curtain. In Ultramarine doctrine, Hyperios systems are deployed in clusters to shield armored columns and critical assets from aerial incursion. Wargear

Tarantula Sentry Turrets: Heavy Bolter

Deployed in overlapping fields of fire, Tarantula heavy bolter platforms provide autonomous suppression against infantry assaults. Patterned with Ultramar’s command-vox protocols, they can be slaved to a Master of Signals for coordinated kill-zones. Low maintenance, high reliability, and near-constant readiness make them ideal for perimeter fortification or rear-line defense. Wargear Kitbash

Siegebreaker: Cassiana Mortivane

To Centurion Mortivane, fortresses are not symbols—they are weaknesses yet to be revealed. She has the rare ability to look upon a defense grid and already see its failure, tracing collapse lines in her mind as though the enemy had drawn them for her. On Varnoss Forgehold, she marked four bastions in silence and brought them all down within a day. At Merovarn Basin, her calculations sealed the breach and cut the Sons of Horus’ counterattack in half. Some say her eye for weak points borders on unnatural. Presca calls it a clarity born of discipline. In the 121st, there…

Tactical Support Squad Caeloria

When walls refuse to fall, when tanks grind a line into stalemate, Squad Caeloria is called, descending from orbit in a drop pod to the exact coordinates where they are needed. Once on the ground, their meltas carve through steel and ceramite alike, making paths where none exist. They are not remembered for glory, but for the unmistakable scent of victory cut from molten ruin. Squad Legionaries Wargear Dedicated Transport Unlike most of its kind that get destroyed or discarded after each mission, Gravis Umbra has been logged in every campaign record of the 121st since the Ophidian Halo. It…

Legion Champion: Aurethia Valensar

Centurion Valensar’s duels are not spectacles. They are judgments. She does not fight for flourish or acclaim, only to prove that no traitor’s blade can withstand the measured discipline of Ultramar. Her record is marked by names, not boasts: the Butcher of Caelen Rift, the Iron Warriors’ Warsmith of Brennos Spire, the warp-marked Centurion who broke the truce at Tevratha IX—all of them fell to her hand. She does not linger over their deaths, only ensures that their fall steadies the line. Her presence at the front is not for morale but for inevitability: when the Champion advances, someone must…

Heavy Support Squad Valthera

When Heavy Support Squad Valthera deploys, they are not assigned a single target or objective. Instead, they are placed at the nexus of the company’s advance, ready to reinforce any line, break any push, or destroy any entrenched position. One moment their missiles carve through enemy armor columns, the next they’re silencing artillery or scattering a charge. In their hands, the launcher is not a blunt weapon—it is the shifting weight that tips the battle. Squad Legionaries Wargear Kitbash

Master of Descent: Athira Solanis

Centurion Solanis was forged in the close descents of Ferric Hold, where the enemy’s fire was as thick as the smoke below. She leads from the front, landing with her veterans in the heart of the breach, turning drop zones into beachheads within minutes. Her calculations are not just numbers—they are instinct sharpened by a hundred descents. Wargear Kitbash

Scorpius Missile Tanks

Armored Support: Scorpius Missile Tank Descent’s Guardian The Scorpius Missile Tank Descent’s Guardian’s first action came in the defense of a crippled Thunderhawk, shielding the crash site with relentless salvos. The pilots didn’t survive—but everyone else did. The crew renamed the tank on the spot. Descent Guardian fires like it’s remembering that moment. Like it still owes someone the next shot. Vehicularis Legionaries Commander Luminique lost both legs and her right eye in the siege of Ferric Hold. She refused reassignment. Refused promotion. She said there was still work to be done. Her new driver, Specialist Corvina, was the one…

Heavy Support Squad Ostoria

They say war is won by those who hold the line—but some lines burn through armor and the occasional daemon or demi-god. Heavy Support Squad Ostoria specializes in anti-materiel strikes, bringing down tanks, transports, and fortified emplacements with clinical precision. When the rest of the company advances, it’s because these ten have already cracked the shell. They’re not loud, and they’re not fast. But when the las-beams converge, nothing walks away. Squad Legionaries Wargear Kitbash

Fulmentaris Squad Antheia

Where most warriors see foes, Fulmentaris Squad Antheia, also known as “The Sagittarii”(Arrow Strike Soldiers),” see heat signatures, elevation, and structural load. It’s not detachment—it’s doctrine. Fulmentaris Squad Antheia operates with deliberate, scientific calm, placing payloads where they’ll change the battle—not just the enemy. On Tevratha IX, their precision strikes saved thousands of loyalist lives trapped behind Word Bearer lines. They didn’t celebrate. They just reloaded. To them, efficiency is mercy. Anything less is failure. Squad Legionaries Wargear Kitbash

Assault Squad Versa

Assault Squad Versa doesn’t hold lines—they collapse them. Deployed in the earliest waves of atmospheric insertion, they strike hard and scatter, only to strike again somewhere else, their jump packs screaming through smoke and debris. They excel in shock engagements and rapid flanking actions, often operating without vox contact when conditions break down. They are not subtle, but they are thorough. Every member has trained in anti-armor sabotage and close-quarters overwhelm. Versa runs them brutal, and they’ve all earned their scars. In missions where timing is critical and survival is unlikely, it’s Squad Versa that goes in first. Squad Legionaries…

Despoiler Squad Rixana

Despoiler Squad Rixana specializes in the moments doctrine cannot predict. When orders fail and plans fracture, they surge forward—not recklessly, but relentlessly. Every clash in the corridor, every breach in the line, becomes their proving ground. They train for unpredictability, drilling until instinct becomes cohesion. They fight as one, loud and brutal, until there’s nothing left but silence—and then they reload, blood-slicked and breathing hard, ready for the next gap in the line. Squad Legionaries Wargear Kitbash

Tactical Squad Ravena

The Remembrancers don’t record much about the squads that hold the middle. But Tactical Squad Ravena has held it more times than anyone can count. They’ve repelled counter-attacks, re-secured breached holds, and waded into the worst of it without a word of complaint. Sergeant Ravena calls her sisters “The Fulcrum,” because the door to victory swings on their steadiness. They don’t break formation. They don’t break tempo. And when the breach is closed and the guns fall silent, they’re already reloading. Squad Legionaries Wargear Dedicated Transport Squad Ravena rides in the Deimos-Pattern Rhino Harmonia Mortem (Death’s Harmony). It has never…

Tactical Squad Quartia

Tactical Squad Quartia is not subtle, and they’re not quiet—but they get results. They’re often first in, last out, and never where command expects them to be. Despite their unorthodox tactics, Legate Presca values them deeply because they win fights that don’t look winnable. They move like a hammer instead of a scalpel, but sometimes a hammer is what you need. It is said their reactor backpacks seem to run hotter and with higher output than the standard MKVI backpack for some reason. Squad Legionaries Wargear Dedicated Transport Squad Quartia rides in the Deimos-Pattern Rhino Portatrix Bellum (War Carrier). No…

Locutara Squad Celestina: The Vindictarii (The Avengers)

Locutara Squad Celestina, known as the Vindictarii (The Avengers), were formed in the aftermath of the betrayal at Tevratha IX. Members were chosen from survivors—those who watched comrades fall under World Eater blades mid-parley, and who returned seeking just revenge, but justice. Now, they strike without warning, without mercy, and without words—only the roar of their jump packs heralds their arrival. Squad Legionaries Wargear Kitbash

Suzerain Squad Nova: The Victrix Honorum (Honored Victors)

Suzerain Squad Nova, known as the Victrix Honorum (The Honored Victors), bear the wounds of victory and the silence of remembrance. They strike not for glory, but for the weight of oaths broken and unbroken. Veterans of the chapter’s earliest compliances in the Ophidian Halo, they know the cost of peace forged by blade and shield. They fought through void-born uprisings, rust-world sieges, and the bitter betrayal at Tevratha IX. During the Shadow Crusade, they stood at the heart of every defensive bulwark and at the head of the most dangerous charges. For them, honor is not a banner or…

Leviathan Dreadnought: Ancient [Leta] Valera

Ancient Valera went quiet after her interment, communicating only in bursts of text, and only the most critical battlefield information. The Mechanicum thinks her vox connection is broken. Her sisters aren’t so sure that’s the issue, and make sure to keep her company when she’s awakened. Wargear
