if this is in the wrong area, I appologise. Please, tell me what you think.


Created a full millennium after the Istan V massacre, the Sons of Mercury share the Salamanders Genome.
With their numbers carved to a handful of Astartes after the Heresy, the Salamanders had no need to fragment their legion into founding chapters as per the writings of the Codex Astartes. However, this did not exclude them from their obligation to the newly appointed high lords of Terra, whom demand 5% of each Chapters genetic material to both monitor against mutation of the progentoid gland and also allow them to create new chapters.
Implanted into Genome-slaves, each Zygote will duplicate, and over a century one thousand genetic organs are created. This organ is the Progenoid gland, or the sacred “gene-seed”. Through his gene-seed a marine may live forever, his memory and experience moving from marine to recruit as his life is spent on the battlefield.
The Sons of Mercury do not forget this sacrifice, and indeed the sacrifice of the man they see as their genetic farther, or their Primarch, Vulkan.
Created during the 13th founding, the loss of their Genetic information by the Adeptus Terra only confirms their divinity in the eyes of the chapter’s chaplains, whom outnumber all other types of officers. Many Veteran sergeants are chaplains in training, and a large proportion of the chapters HQ is given over the Chaplains, and to a lesser degree, Librarians whom both often serve duel roles as Captains. There are of course Astartes brothers with neither the blessing of soul armour or psychic talents whom make outstanding soldiers and leaders none the less.

Having no home world, Mercury itself being little more than a planet wide Iron ore mine, the Chapter is a fleet based force, with no less than three battle barges, “The Murasame”, “The Word of the Emperor” and “The Neverender”. These ships, a trinity forming the crux of the Sons operations, are all crafted from Steel, Iron, Obsidian, jet and Marble found on or within the blasted surface of the water star, Mercury. It is from this the Marines take their name. Even among ships of the Astartes, the vessels of the Sons are beautifully crafted and elaborately decorated.

Acting as an Astartes should, each brother swears an oath on reception of their black carapace to never take a step back from the enemy, and to never allow an unarmed citizen of the Imperium fall in their sight. With these oaths in mind, the SoM have been responsible for the saving of countless lives across the Imperium.
On Brachium, a dense forest world beset by an ork Waaaargh!, the Sons of Mercury used their Rhinos and Razor backs as make-shift ambulances and refugee busses, ferrying innocents away from the advancing horde while the attached tactical squads fought a fiery rearguard action, and the guns of their predators blazed against the orks.
On the world of Probitas, the entire 5th Company was lost to a black skinned Tyranid horde, the battle brothers of the Adeptus Astartes refusing to fall back until each civilian was clear of the space ports. Surrendering their own Thunderhawks for the task as they where overwhelmed. Refusing to surrender, they were all consumed by the great devourer along with those not swift or lucky enough to make it off planet. In memory of their glorious sacrifice in honour of the Emperors Imperium, the Company was rebuilt with recruits found among the survivors of Probitas. They named their company “Amor”, or “The Beloved” in remembrance of those who gave their lives for theirs.

In the system of Shamshir countless lives where saved after the skilled assassination of a rebel planetary governor during his election address. Before amassed ranks of seditious guardsmen and wavering civilians the traitor general was felled by a snipers bullet from over 3 miles away; no doubt the work of an infiltrating scout team who snuck away undiscovered, and brought back with them an entire squad of 1st Company veterans in tactical dreadnought armour; more than enough to quell the populace and wavering guardsmen regiments into place. The message was clear and effective; we walk among you as gods. Falter and die.

Their record is not without its black marks, however. During the 38th Millennium the current Chapter Master, Bhall Murasame ordered his 3rd company, along with Element of the 1st and 10th to a planet known as Cadacius. The population was in full revolt against the will of his immortal majesty. Daemons had begun to arise in populated areas, slaughtering and spreading mutation and heresy. Guard regiments had turned or been slaughtered, head quarters shattered, bringing the planet to its knees.
The arrival of the Astartes swung the war quickly, those thronging the space ports brought with the wounded to the spacious but Spartan safety of the Strike cruiser “Crowning” and its holds and decks while the Astartes and survivors made war together on the planets surface. Within a fortnight the heart of the cancer had been found, and a surgical strike was launched against it. Terminators teleported into the crux of the battle as drop pods fell like rain from the sky. In the ruins of a blasphemous temple the planets clergy was found, consorting with dark gods. Bhall personally slaughtered each of them, ordering their bodies to be displayed in crucifixion, as befitting traitors and heretics. From the fell church he took only a sword, its blade warped and twisted, its hilt perfection, and then returned to the “Crowning” alone. The area was reduced to a mile wide crater via orbital bombardment.
All seemed normal, and the fleet was ready to depart. Alas as the Strike cruiser made course for the RV with the rest of battle group its hull was wracked with cataclysmic explosions. Its plasma drive detonating with the energy of a dying star, the munitions detonating within the armour belly of the craft, superheated debris crippling no less than 3 cruisers that hung in low orbit with it as it detonated in a shower of shattered steel, marble and jettisoned drop pods. The Marines one again made planet fall. A brief but bloody struggle broke out. Outnumbered, the renegade marines made war against their former brothers, 3rd company traitors slaughtering isolated scout teams in the field before making open war on the veterans of the first company. Garbed in blessed TDA, Master of Sanctity Samuel fought his way to the heart of the fighting, striding towards Bhall as the Assault cannons of his retinue reaped a bloody tally among his body guard. The former chapter master was not as he was remembered, however, his body mutated and warped, his form now monstrous, his right arm fused at the hand to an oversized perversion of the sword he had found. The two fought among the carnage, and after an hour of visceral personal combat Samuel emerged victorious, drawing his Crozius from Bhalls ruined chest with a roar of triumph; Their would be no mercy for those who had turned. Each one was put to the sword.

Combat Doctrine

Unlike their parent chapter, the Sons of Mercury forgo close quarters fire fights, preferring instead to fight at longer range, weakening their foes with a withering barrage of fire before designated close combat units break through the enemy line and destroy the enemy proper. While Melta and flamer weaponry is used as needed, it is not favoured. Indeed solid round ordnance, such as Whirlwinds and rocket launchers make up a large part of their long range battle plan, with Terminators and assault squads forming the crux of the killing blow. These units rarely if ever deploy with the tactical, devastator or armour support squads, instead performing daring teleportation attacks or halo drops from Thunderhawk gun-ships. When attacking from the ground, the Terminators of the first company ride within the armoured confines of the sacred Land Raider and its many variants, disembarking under a curtain of covering fire, as befitting the Sons of Mercury’s methods of war. The ferocious close combat actions are almost always led by a chaplain, whom chants litanies and spurs his brothers onto greatness while filling the heart of his foes with dread.

Drop pod assaults are a rarity; close to all SoM vessels having traded their drop pod ports of extra teleportation bays and orbital bombardment cannons. Indeed, using these two elements in tandem is a favoured shock tactic of the chapter; Shelling an area to dust before fazing its best warriors in to the ruins and confusion to swiftly end the fight.


The chapter is organised according to the Codex Astartes. Each company from 1 through to 5 are battle companies, with 6 to 9 being reserves. The 10th acts as the scout company, and can be of infinite size. The first company, unusually large for its type, ranges from between 100-130 warriors. Each battle and reserve company maintains effects and weapons for 100-150 warriors. The Large size of the Chapter grants it great flexibility but also, unfortunately, unwanted attention for the forces of the Inquisition. As it stands, it is left as is, with numbers being recorded at close to 2000 members, including scouts but excluding support staff. Still, the Sons of Mercury got to great lengths to refer to themselves as a “chapter” and not a “legion”.

A large portion of the chapters command and control is compromised of chaplains, who lead their brethren into battle as well as oversee their spiritual development as befitting their role within the chapter as laid out by the Codex Astartes. While Line officers and Librarians play their role, they are very much secondary to that played by the Chaplains of the chapter.

With no home world, the Sons of Mercury maintain and operate a vast navy or no less than three Battle Barges, and Nine strike cruisers. They also have access to a flotilla of frigates and escorts.

First Battle Barge: Word of the Emperor
Second Battle Barge: Neverender
Third Battle Barge: Murasame

First Strike Cruiser: Oath Keeper
Second Strike Cruiser: Unbound
Third Strike Cruiser: Shin Hado
Fourth Strike Cruiser: New Dawn
Fifth Strike Cruiser: Nova Pentacle
Sixth Strike Cruiser: Nobility
Seventh Strike Cruiser: Redemption
Eighth Strike Cruiser: Masters Hand
Ninth Strike Cruiser: Ninth Gate


The Sons of Mercury share the belief of that most space marine chapters in the 41st Millennium hold. That the Emperor, while their genetic father and the very pinnacle of humanity, was only a man. A remarkable and much loved man, but a man none the less, and not a god.
This view, along with their rather ample chapter size does bring them into conflict with the ecclesiarch from time to time, but conflicts have been brief and losses small.
With such a high number of Chaplains reverence of the Emperor plays a major in the chapter, perhaps rivalling that of the black Templar. Prayer often refers to the Emperor as “the Father”, as the Sons of Mercury view him as such, their Genetic and biological father.

The Gene-Seed of the Sons of Mercury shows minor mutations that leads to a paler than normal skin tone, sometimes down to an absolute white, often with hair to match. All SoM develop rich, violet or purple eyes one zygote implantation begins, as well as a slightly high bone density than normal. It is unknown where the mutation arises from.


“Never give up! Never Surrender!!”

A quick read through and this looks good. Do you have any ideas for a color scheme and chapter symbol? Do you have any pictures of your marines that indicate the actual scheme for this chapter? If not, do you have an image of their color scheme from Bolter & Chainsword's Marine Painter, GW's Interactive Marine Painter, or some other tool?
