"Honor our fathers, protect the innocent and meek, demolish and burn those that would oppose the Emperor's subjects. These are the tenants of our righteous calling, and they are our creed! Glory for the Emperor, and honor to his servants!"
— Lord Marshall Drakor addressing the victorious Chapter after routing an army of Chaos Marines (854.M41)

The Sons of Galastram are a 25th FoundingSuccessor Chapter of the honored Penitent Knights Chapter. Created during the 40th Millennium, the Sons proudly adhere to the near chivalric culture of their forebear Chapter, adopting many of the customs, strategies, and beliefs. Like the Knights, the Sons fervently believe in the value of civilian life and will gladly endure many hardships to secure their safety. Because of this, or perhaps the reason for it, the two Chapters have maintained a very close relationship, the younger Chapter seeing the Knights as their noble fathers. However, differing from their parent Chapter, the Sons of Galastram are mostly a crusading Chapter, roaming the Imperium for foes to slay, though sometimes taking periods of time to defend their parent Chapter's Sub-sector to rebuild their ranks. But while the Penitent Knights care surprisingly little for their mysterious origins, the Sons have made it their mission to seek the answer to the origination of their gene-seed. Additionally, the Sons greatly enjoy contests of skill at arms, more so than other Chapters, going as far as to hold continuous tournaments aboard their great Battle Barge, the "Anvil of Valor."

Chapter History

One of the many noble and respected Chapters raised from the 25th Founding, the Sons of Galastram were given a struggling Imperium to defend and maintain, like all of their ilk. By their own reputation, the Sons are an honorable number of the Adeptus Astartes, and are inheritors of long refined traditions and beliefs of their parent Chapter, the Penitent Knights. Since their creation, the Sons of Galastram have established themselves as noteworthy editions to the ranks of the Imperium's bulwark, and as fierce upholders of the faith of their father Chapter, the Asterian Cult. Fervent in the holiness of the human soul and form, the Sons of Galastram will rarely and heavy-hardheartedly take negligent actions in regards to civilian life.

Their variation of the Imperial Cult, while containing the belief that the Emperor of Mankind is indeed a deity, has led the Sons of Galastram to clash or come to odds with other Imperial forces, whether on matters of tactics or theology. Because of this, the Sons have learned to keep their beliefs quiet until they are threatened or tested.

Though aside from matters of faith, the Sons of Galastram had aroused some controversy when they were to be founded from the gene-stock of the ancient Penitent Knights Chapter, itself having a troublesome relationship to the High Lords of Terra, and the Inquisition. But flawed as their relations were, few could refute the Penitent Knights' effectiveness in the defense of their home, the Asteria Sub-sector of Segmentum Obscurus. Long had the war-tested Chapter stood valiant against the grasp of the alien and heretic, and a gamble was taken to use a Chapter founded from the Knights to become an ever-Crusading force, always on the offensive.

Once founded, the new fledgling Chapter was given the name "Sons of Galastram," taken from Lord Crusader Galastram, who is still to this day considered one of the greatest Chapter Master of the Penitent Knights. And moreover, the Penitent Knights further bestowed other gifts upon their new successors, including several relics of their own Chapter, as well as the dark secret regarding the dreaded Crow's Children Chaos Warband, and its origins in the traitor Order of the Crow, a company of the Knights. But one secret they could not impart unto the Sons of Galastram was the origins of their shared gene-seed, a mystery that likely only the Mechanicus or the Adeptus Terra could unravel.

The final gift the Penitent Knights offered the Sons was lordship over the Feudal World of Ostrava, a dusty planet of long fields and towering mountains, whose inhabitants had grown strong and suitable candidates for recruitment through continuous war and hardship, a way of life that became ingrained in the Sons of Galastram, constantly engaging in sparring and combat drills to achieve the greatest personal effectiveness for each battle-brother.

Notable Campaigns

Coming of the Scions (812.M40) - Following their exemplary and heroic actions during a campaign against a Chaos worshiping insectoid xenos race known as the Vya, and their celebrated success during the battle known as "Galastram's Charge," the Penitent Knights Chapter was given the honor of siring a new Successor Chapter, that being the Sons of Galastram, named after the legendary Lord Crusader of the Penitent Knights. The Knights were heavily involved with the beginnings of the new Chapter, devoting an entire Order, or Company, to ensure that the young Astartes would receive the best training they could, even so far as to grant the Feudal World of Ostrava for the Scions to found and build their Chapter. Soon after the Sons were considered ready for action they left the Aegimius System to patrol around the Gothic Sector for Crusades to join, eager to prove themselves.

The Crucible (814.M40) - After two Terran years of light engagement with roaming bands of xenos races, the young Sons of Galastram Chapter found itself engaged in a much more serious war. As Chaos had begun to gain momentum in Segmentum Obscurus, and a warband of Black Legion marines crossed the path of the Sons of Galastram. The loyalist Astartes found the Chaos Marines upon an unnamed Death World, where the Chapter Master, or Lord Marshall, as their culture dictates, ordered the Chapter's fleet engage the traitor warships while three of the Orders (Companies) brought battle to the Black Legion Warband on the surface of the Death World. The relatively young Astartes faced traitors with far more experience, and though few in number, fought as fiercely as could be expected. The Warlord of this Warband then used some strange technology to trap the Orders of the Sons of Galastram upon the Death World for weeks by making the planet's atmosphere extremely hazardous to prevent the use of aerial vehicles, subjecting them to arduous trials and ambushes. However, the Lord Marshall, Cadlaine, freed his brothers by slaying the Warlord and destroying the weather device. The Sons look back on this event as their first true trial.

Lord Marshall Cadlaine, after returning with the survivors of the encounter, deemed that the Chapter's brothers needed to be more ready for such battles, and thus, aboard the Chapter's immense Battle Barge, the "Anvil of Valor," a grand arena was fashioned to host a constant tourney of squad-based fights between the Scions or against captured xenos beast races. Cadlaine named this tournament, the Crucible. Using non-lethal weaponry against brothers, the Sons would be a constantly sharpened blade, always improving their skills between glorious battles in the Emperor's name, or to bring pride to both the them and their progenitor Chapter.

Burning of the Carrion (554.M41) - For great many millennium, the horrendous Crow's Children Warband of heretic Astartes called the Space Hulk, the Dark Carrion, their den. And for all those long years, the location of the dark construct remained hidden and elusive, to both the Penitent Knights and the Sons of Galastram. But in the mid of the 41st Millennium, the Sons had finally discovered the Dark Carrion, hidden deep within the ungoverned and wild reaches of the Asteria Sub-sector. Immediately, the young Chapter sent word to their progenitors, but also set about working to destroy the outer defenses of the Space Hulk. For not only had the Crow's Children constructed nigh-impregnable hull modifications and bastions upon the Carrion's surface, but the traitor Astartes had also built smaller fortresses and installations across the void around the Space Hulk's position. The Sons set themselves to task by besieging the smaller fortifications in smaller strike forces, bringing down the hammer upon the anvil, as they would say. These operations were largely successful, as the small fortresses were garrisoned by mercenaries and blackguards from the Crow's Children mortal followers, with a few Astartes present to maintain control. Over the course of two standard weeks, the Sons of Galastram were then joined by the Penitent Knights.

After pleasantries and fair tidings, the two Chapters with their combined fleets managed to smash through whatever ramshackle pirate or pillaged Imperial vessels the Children had amassed for their defenses, but all became far more sobering whence both armies saw the monstrosity that was the Dark Carrion. On top of the incredibly sturdy hull of the Space Hulk was several layers of reinforced bulkheads, with spires and bastions that bore a striking resemblance to the Penitent Knights' fortress-monastery of Galadhor, as well as almost innumerable cannon embankments. To further the gravity of the task, the Lord Scholar of the Knights made the discovery that a cabal of Sorcerors were casting disruptions that made the use of teleportariums to reach the inside impossible. And so, the Lord Marshall of the Sons created the plan of using the battle-barge Valiant Scion to smash into to Carrion and deposit the elite of his Chapter into the Children's dark home.

Through fire, plasma, and heretical fury, the Scion smashed into the hiding place, and a joint force of the Orders of the Silver Blade, and Blessed Gauntlet, scoured the foul innards of the Space Hulk. Every step of the way, they were beset by Chaos Marines and the Warband's reckless and mindless followers. So bloodthirsty and dangerous were the Children that by the time half of the defense cannons were disabled, the Sons of Galastram's force was reduced to half strength. The Lord Marshall, Aethelar Perro, ordered the wounded of the force to return to the Valiant Scion and hail rescue while the rest of the Sons continued onward. The terrible truth of what befell the large party is that the Betrayer himself, Daedelus, descended upon the loyalists and tore them apart with his Raptor chosen, in a bloody battle near the engine compartment. It is speculated that one of the Sons, seeing the desperation of their situation, had somehow detonated a large explosion in the compartment, starting a chain reaction across the Dark Carrion. Though much of the Crow's Children managed to escape the destruction due to teleportation by Peredrath the Ruiner, they had been punished for their sins with the destruction of their den. Mourning the selfless sacrifice of the Sons of Galastram's elite, the Penitent Knights declared Aethelar and his fallen brothers heroes of both of their Chapters.

Dark Calculation (120.M42) - By the time of the Forty Second Millennium, the Sons of Galastram had done well for themselves and earned honor and prestige for their bravery on the battlefields of Segmentum Obscurus, and were reconquering the Hive World Ciarra under occupation by the Black Legion. With most of the Chapter deployed on Ciarra to recapture the Hive Cities, the Crow's Children force of Plague Marines, revitalized under Peredrath the Ruiner's guidance, launched a surprise attack on the Sons of Galastram flagship, Anvil of Valor, and unleashed a viral plague into the Battle Barge's air filtration and rendered it uninhabitable, as well as slaying the wounded and token battle-brothers aboard the Anvil.

Crippled by this insidious strike, the Sons of Galastram's pride and honor were shattered, and there was a lingering doubt in the minds of the Chapter that the sacrifice of Aethelar Perro and his chosen elite marines to destroy the Children's Space Hulk-turned Star Fortress, was made pointless as the Warband seemed to be flourishing regardless. But the current Lord Marshall, Drakor Karrios, dismissed these doubts by heroically capturing the capital Hive of Ciarra and led his Chapter on a hunt for the Plague Marines that humiliated them so.


Following in the example of the Penitent Knights, the Sons of Galastram took their progenitor's ideas even further and divided their numbers into a mere three great Orders. Said Orders are: the Order of the Silver Blade, Order of the Blessed Gauntlet, and the Order of the Iron Steed.

Names eluding to their purpose, the Silver Blade exalt the thrill of melee combat and train rigorously with chainsword and power weapons and thus is mostly comprised of Crusader (Assault) squads. The Blessed Gauntlet, conversely, prefer to utilize bolter and heavy weapons to rain a hateful storm of the Emperor's wrath upon their foes with Tactical and Devastator squads. Finally, the Iron Steed bring all manner of vehicles into battle alongside their brethren such as Land Raiders, Predators, Whirlwinds, Razorbacks, as well as the Chapter's aerial arsenal.


As the Sons of Galastram are a fleet-based Chapter, they do not have any one planet to draw Aspirants from, unlike the Penitent Knights. Thusly, the Sons will examine the populace of a world they've either fought on, or helped save, and will recruit from there. No matter what background these neophytes come from, they are taught to both respect and adhere to the ways of their Chapter. And when a group of neophytes are deemed ready, they will enter the Crucible and spar against one another. Those that excel or otherwise impress the present Chaplains will be selected for admission into the ranks of the Sons of Galastram, whereas the other "failed" neophytes are either allowed to become the Chapter's serfs, or may try a second and final time in the next bout of neophytes.


Inheriting their sacred Gene-seed from their parent Chapter, they also inherited the mystery of its origin. To this very day, both the Sons of Galastram and Penitent Knights are unaware of which Primarch is their gene-father.

Combat Doctrine

As they are an entirely mobile and fleet-based Chapter, the entirety of the Sons of Galastram often deploy alongside each other. Thusly, all three of the Orders will land on the battlefield, with the Silver Blade usually establishing a forward position, the Blessed Gauntlet following closely behind to reinforce said position, and finally when the Iron Steed makes landfall, both of the other Orders will receive the support of roaring vehicles and bike squadrons.
