"I have lost brothers, aye, and wept over their graves. Good men deserve tears to mark their passing. Even the Emperor weeps when His warriors fall. Royal thralls gather that mourning dew in blessed vials, to be treasured as relics forevermore. Regret is weakness. Guilt is weakness. But sorrow? Sorrow is a chamber in any soldier's heart. Sorrow is felt even by the divine."
- — High King Arucatas, Chapter Master of the Emperor's Spears
The Emperor's Spears is a Loyalist Space Marine Chapter and successor of the Ultramarines. The Chapter was created during the 25th Founding in the latter half of the 40th Millennium, the so-called "Bastion Founding." The Emperor's Spears hail from the feral Ocean World of Nemeton.
The Emperor's Spears was one of three Chapters, including the Celestial Lions and the Star Scorpions, that once made up the Adeptus Vaelarii, better known as the Sentinels of the Veil. These Astartes guardians once stood watch over the twenty Imperial worlds located in the backwater region of the galaxy's Ultima Segmentum called Elara's Veil on the very edge of the intergalactic Outer Dark.
Despite its distance from the heart of the Imperium, the Emperor's Spears received the technology and knowledge of how to create Primaris Space Marines or transform Firstborn Marines into Primaris Marines by crossing the Rubicon Primaris from an Imperial Torchbearers task force.
Due to separate tragedies suffered by their fellow Chapters among the Sentinels of the Veil, only the Emperor's Spears remain as the stalwart protectors of the scattered worlds of this region from the horrors of the Outer Dark.
Only time will tell if this Chapter will be able to maintain its vigil successfully, for it is a depleted force on the Imperium's benighted frontier.
Chapter History
Origins

While records on the origins of the Emperor's Spears are scarce, the first recorded encounter with the Chapter came in 594.M40, suggesting they have been defending the Imperium for perhaps a standard millennium and a half, making them relatively young by the standards of Space Marine Chapters.
Upon their inception, they were charged with standing sentinel over the scattered worlds of the Elara's Veil region of Ultima Segmentum, ever watchful for insurrection and rebellion, as well as external threats. This backwater sector of the galaxy was once protected by the oath of unity sworn by three mighty Chapters of the Adeptus Astartes called the Adeptus Vaelarii -- the Star Scorpions, who were undone by flaws in their genetic coding; the Celestial Lions, who were ravaged by the Inquisition for sins they did not commit, and the Emperor's Spears. Now, after hundreds of standard years, the Emperor's Spears are the only ones to still keep their vigil. They are barbarian watchmen against the Outer Dark; bloodied but unbroken in their long duty.

Even in their relatively short history, the Emperor's Spears have clashed with their fellow Space Marines, notably the Aurora Chapter during the Eukari Insurrection. So ruinous was the conflict between the Chapters that the Ultramarines sent representatives to quell the unrest, ruling that the Emperor's Spears had acted rashly and were to blame for the blows that were exchanged.
It is only in recent years that High King Arucatas the Swordbearer has eased the tensions that ensued between the Chapter and the other descendants of the XIII Legion of old. No records exist of the Emperor's Spears and Aurora Chapter fighting alongside one another in the seven Terran centuries since the incident.
Era Indomitus
Since the opening of the Great Rift at the dawn of the Era Indomitus, the Emperor's Spears have been beset by new dangers. The Rift is visible from Nemeton, and its baleful influence has been felt across the Elara's Veil region. Hard-pressed by constant war and isolation following the loss of their fellow Chapters of the Adeptus Vaelarii, the Emperor's Spears now stand upon the brink of destruction, and it remains to be seen how its future will unfold...
Notable Campaigns
- Eukari Insurrection (330.M41) - The Imperial world of Eukari was struck by a rebellion led by the forces of Chaos in 330.M41. In response, its planetary governor sent an astropathic plea for aid. As Eukari lay within the region of Elara's Veil, it was within the sphere of responsibility of the Emperor's Spears. The Chapter dispatched a strike force led by Captain Trystance to aid the world. When the Emperor's Spears force arrived, Trystance discovered that the Aurora Chapter was already fighting the rebels. The Aurora Chapter commander berated the Emperor's Spears upon their arrival for failing in their responsibilities to guard the Veil and requiring others to fight their wars for them. This angered Trystance and he ordered the Emperor's Spears' strike force to deploy right into the heart of the rebels' capital city. Though they suffered heavy casualties, over three solar days of fighting, the Emperor's Spears killed the rebel Chaos Lord and thus earned the majority of the glory of the battle for themselves. Trystance then informed the Aurora Chapter's commander that they had had no right to mark the Battle of Eukari as a victory on their war banners, since the Emperor's Spears had actually carried out the operation that resulted in the defeat of the rebels. This led to a squabble between the two Astartes captains, which ended in an honour duel between both Chapter's champions. Yet even this failed to stop the bickering, as the duel proved inconclusive and both Chapters claimed they had won the duel. Eventually a shot rang out and both sides attacked the other in an internecine battle, which resulted in even their orbiting fleets unleashing their weapons upon one another and causing significant damage before a ceasefire was eventually declared to stem the losses. Since both Chapters were Ultramarines successors, the Ultramarines dispatched a group of representatives to finally end the conflict. Upon further review, the Ultramarines ruled in the Aurora Chapter's favour and held that the Emperor's Spears had acted impulsively. The Ultramarines arbitrators also found that the Emperor's Spears had not followed the dictums laid out in the Codex Astartes. As a result, the credit for the victory over the rebels was to be shared equally between the two Chapters. Though the Aurora Chapter was satisfied with this decision, Trystance was infuriated at the outcome, and vowed he would never set foot on the Ultramarines homeworld of Macragge again even if the home of his primarch found itself imperiled. The Emperor's Spears bitterly claimed the outcome was the result of the Ultramarines' cultural inflexibility as a Chapter and their expressed preference for the Aurora Chapter as an organisation that was more compliant with the dictates of the Codex Astartes than the Emperor's Spears. Thereafter, the Emperor's Spears no longer had a close or cordial relationship with their two brother Chapters.
- Battle of Sythaur (Unknown Date.M41) - It was during this campaign that Sergeant Faelan of the Kavalei tribe, a future hero of the 3rd Warhost, received a grievous wound that disfigured his face.
- War Against the Exilarchy (ca. 999.M41 - Present) - The birth of the Great Rift cut off the region of Elara's Veil from the wider Imperium, trapping it within the darkness of the Imperium Nihilus. At that time, a great Chaos warhost known as the Exilarchy came into being, comprised mainly of Humans and mutants, but supported by a small number of Heretic Astartes warbands. The true rulers of the Exilarchy were the Chaos Space Marines known as The Pure, the remnants of the Star Scorpions Chapter, who had been declared lost in the Warp. The Pure used the rest of the Exilarchy forces as foot soldiers to further their cause. In the aftermath of the Great Rift's creation, The Pure and the Exilarchy were expelled from their travels through the Warp into Elara's Veil. The worlds of the Veil were part of the Emperor's demesne, but The Pure sought to conquer them and reclaim the region they had once helped to defend in the name of the Dark Gods. This brought them into conflict with their former allies the Emperor's Spears and Celestial Lions Chapters, who were charged with protecting the worlds of Elara's Veil. Due to the sheer numbers of the Exilarchy war host, eventually half of the worlds of Elara's Veil fell to The Pure's control. The Emperor's Spears, the Celestial Lions and the rest of the Adeptus Vaelarii waged a slowly losing campaign against the forces of the Exilarchy. After over a Terran century of warfare, there was no longer any doubt that the Exilarchy and its Heretic Astartes masters had the upper hand.
Chapter Organisation

Captain Brêac, Force Commander of the Emperor's Spears 3rd Warhost
The Emperor's Spears divert substantially from the organisational dictates of the Codex Astartes. They have a vast Chapter fleet, and specialise in air-to-ground warfare and orbital drop assaults. They are particularly mobile when it comes to deployment and redeployment, and are not short of air assets.
The Emperor's Spears often ally with the military forces of the Adeptus Mechanicus and Skitarii Legions of the Forge Moon of Bellona in their own star system and Imperial Knights from Raukama, a Knight World located in Elara's Veil.
The Chapter is organised into what it calls "war hosts" instead of the traditional ten companies. These are autonomous units of variable tactical composition that often range far from Nemeton in defence of Elara's Veil. The Chapter Master of the Emperor's Spears is known as the "High King" while its captains are called "Warhost Lords."
The Chapter's Veteran 1st Company is called "the Paragons." These warriors forsake any chance to rise further in the Chapter's hierarchy to join the Paragons, and it is believed that they must undergo blood rites and other hidden rituals to gain their elite position. On the battlefield, they are fierce hunters, focusing on the elimination of enemy leaders.
Chapter specialists known as "Druids" replace the usual Librarians, Chaplains, Techmarines and Apothecaries of Codex-compliant Chapters. These warrior-priests are always ready to harvest the gene-seed of their fallen battle-brothers, as well as performing the traditional duties of the standard Codex roles based on their specialist skills and esoteric abilities.
Chapter Combat Doctrine

An Emperor's Spears Primaris Space Marine Lieutenant in battle.
Imperial tacticians have chronicled the Emperor's Spears as exemplars of a close-assault ideal. Via Drop Pod and gunship, the Emperor's Spears descend into the heart of the enemy and hold position long enough for other Imperial forces to advance untroubled, linking up with their vanguard.
Witnesses cite that Emperor's Spear warriors aren't the berserk madmen one might expect of tattooed savages, but instead wage war in bursts of adrenal fury tempered by periods of chanted tribal dirges. Their way of waging war is chimeric in that regard, as conflictingly melancholic and joyous as the barbarians of Nemeton themselves.
Imperial commanders have, in the past, accused the Emperor's Spears of being unreliable, noting that the Chapter expresses traditional Space Marine autonomy to a difficult degree. Cries for aid are answered, but without always coordinating with the Imperial forces on the ground.
The Chapter has always made efforts to minimise collateral damage, but Emperor's Spear strike forces have been known to plunge into battle, pitting glory above prudence, as if the Chapter's youth meant its warriors had something to prove to its older brethren. Desperation in recent solar decades has forced the Emperor's Spears into a more cooperative mindset, however. Necessity has forced their hand; with Elara's Veil in such danger from the Archenemy, pride can no longer come first. Now, survival must.
Compared to many Space Marine Chapters, the Emperor's Spears are devastatingly well-equipped for orbital and deep-void warfare, primarily due to the scale of their fleet and their experience in grinding void warfare. On the same note, their alliance with the Forge World of Bellona means that all but the most distant warhosts possess abundant war machines, ammunition and materiel -- as well as allied contingents of Adeptus Mechanicus soldiery clad in Bellonan red and black.
Chapter Homeworld

The Emperor's Spears' Chapter planet of Nemeton, an Ocean World.
The homeworld of the Emperor's Spears is the Ocean World and Feral World of Nemeton located in the Annwyn Reaches sub-sector of Elara's Veil. Its landmasses are small and mountainous, and heavily forested. There are several equatorial landmasses that are largely marshy jungle. Due to the temperate weather, rainfall is constant across most of the surface.
During the late 30th Millennium Nemeton was brought into Imperial Compliance during the Great Crusade by the Ultramarines Legion. Over time, however, the people of Nemeton rejected the advanced technology and attempts at urbanisation brought about by the Imperium and instead returned to the primitive lifestyle they had known during the Age of Strife of living as pre-industrial tribes in the wilderness. Nemeton is still dotted with the ruins of the ancient, abandoned cities the Imperium tried to build after making first contact. Technologically, the world's people have maintained a society equivalent to that of Old Earth's Iron Age.
Nemetese Society
The Twelve Tribes of Nemeton represent a mono-culture of interacting pre-industrial Human tribes who loosely share certain touchstones, including beliefs, cultural practices and a language. As Elara's Veil is a crimson-coloured nebula that takes up most of Nemeton's night sky, the Nemetese tribes have come to believe that rain is something superstitious and sacred born from the great lights in the sky, a belief that is considered borderline heretical by many of the more conservative factions of the Imperium.
Elara's Veil is named after the legendary hero Elara, a significant figure in the mythology of the people of Nemeton. Worshipped by most of the peoples of Elara's Veil, Elara's actual historical origin remains unclear. It may be the name of the Imperial Commander or a saint of the Imperial Cult who first brought the region into Imperial Compliance. To the primitive peoples of the Veil, however, she is the Emperor's bride and her crimson funeral veil became the nebula that now bathes the stars red. The Emperor is said to weep over her loss, producing Nemeton's constant rains.
The relationship between the Chapter and Nemeton's people is very different from that of most Space Marine Chapters and their recruiting stock. The superstitious tribes see the Space Marines as the spirits of lost children, taking their young before their time and leaving them simply ghosts to be mourned.
The most esoteric belief held by the natives of Nemeton is that of the geas. Every child of the tribes is brought before a local shaman known as a "druid" who is usually a psyker at sometime after their birth, who reads the flow of fate in their blood. The nature of geases vary wildly, though all are semi-supernatural "promises" of a specific moment or choice in the child's life to come.
The Emperor's Spears believes that Nemeton's seers read these futures through the Warp's echoes, like any actual precognitive prophecy, and armed with this poetic foreknowledge, the bearer of the geas can hopefully avoid the wrong choice when the time comes. Many geases take the form of warnings against dishonour or death should the bearer ever act in a certain way.
The written runic language of Nemeton, dubbed the "Runes of Ogham," is incomprehensible to most outsiders, though the Nemetese spoken language is one of the myriad Human dialects dubbed Low Gothic.
Nemeton itself is a curiously well-defended world. A large minefield protects approaches to the planet, while many of the rocks that make up Nemeton's rings have been turned into weapons platforms capable of bombarding attackers with waves of deadly torpedoes.
Further defences come from the Tech-priests of Bellona, a Forge Moon in the Nemeton System. The Emperor's Spears have formed close links with Bellona's Adeptus Mechanicus leaders, and together they are the foremost defenders of Elara's Veil.
Notable Tribes of Nemeton
The people of Nemeton are divided into twelve tribes, which are further sub-divided into clans or related families. The Nemetese tribes are all culturally primitive, evidencing a technological level no more advanced than that which prevailed during Old Earth's Iron Age in the first millennium B.C. despite the attempt of the Imperium during the Great Crusade following Nemeton's original Compliance action to resettle the population in cities that maintained the standard levels of Imperial technology. The following tribes are the most well-known.
- Arakanii - The Arakanii are a coastal tribe, known for their battlefield scavenging, as they loot the dead of other, larger clans after tribal wars. Some of the oldest chronicles still extant on Nemeton even recorded witness-oaths seeing the Arakanii devouring the flesh of the dead.
- Kavalei - The Kavalei are the "Clan of Kings," a vast and sprawling tribe that eclipsed all others in terms of territory and victories in tribal war. As the most populous clan on Nemeton, most Emperor's Spears Astartes are descended from the people of the Kavalei.
- Novontei - The Novontei are a clan of wanderers and scavengers, going from region to region, island to island, offering their services as mercenaries and itinerant druids, preferring to serve rather than raid. The other tribes see them as a breed of necessary vermin, useful in battle and for the secrets kept by their druids, but disparaged for their lack of territory and loyalty.
- Vargantes - The Vargantes are a small northern tribe.
Notable Emperor's Spears
- High King Arucatas the Swordbearer - Arucatas of the Kavalei tribe is the High King of Nemeton (essentially its planetary governor) and the Chapter Master of the Emperor's Spears. One of his most notable actions was over-turning the vow of Lord Trystance of the 6th Warhost to never to set foot on the Ultramarines Chapter's homeworld of Macragge again, following the bitter outcome of the Eukari Insurrection. Arucatas explained his reason for doing so by citing Trystance's vow as an oath of spite and fire, made in the heat of the moment. Despite his ruling, however, the relations between the Emperor's Spears and their progenitors the Ultramarines were not restored to their former amity and there is still little affection between them.
- Warhost Lord (Captain) Brêac - Brêac of the Vargantes tribe is the captain or "Warhost Lord" of the Emperor's Spears 3rd Warhost.
- Warhost Lord (Captain) Trystance - Trystance of the Arakanii tribe was the captain or "Warhost Lord" of of the Emperor's Spears 6th Warhost during the Eukari Insurrection. The bitter outcome of that conflict led Trystance to vow never to set foot on the Ultramarines' homeworld of Macragge again, even if the world of the Emperor's Spears' primarch was itself imperiled.
- Warhost Lord (Captain) Yvas (KIA) - Yvas of the Novontei tribe was the captain or "Warhost Lord" of the Emperor's Spears 6th Warhost. He was killed when his warship Skyreaver fought alongside the Raven Guard warship Second Shadow.
- Warhost Lord (Captain) Serivahn - Serivahn of the Vargantes tribe is the flagship captain of the strike cruiser Hex. His body was painfully deformed, having partially rejected the Primaris Alpha and Beta phases of gene-seed organ implantation which had left him in constant pain. This was because the Emperor's Spears had found the process of creating Primaris Space Marines difficult and not easily mastered even once they had received the technology and knowledge of how to do so from an Imperial Torchbearers task force. Many of the first aspirants to become Primaris Marines of the Emperor's Spears did not survive the process as a result. Serivahn was the first to do so, despite his resulting infirmities. But Serivahn's survival did allow the Emperor's Spears to further refine the techniques for the creation of Primaris Marines so that no others suffered Serivahn's fate.
- War-Priest (Druid) Ducarius - Ducarius of the Kavalei tribe is a War-Priest or "Druid" of the Emperor's Spears' 3rd Warhost.
- War-Priest (Druid) Tolmach - Tolmach of the Novontei tribe was a War-Priest or "Druid" of the Emperor's Spears' 3rd Warhost. He was slain by the Chaos Space Marines of The Pure who boarded the strike cruiser Hex. His gene-seed and Astartes organs were later used in the process to turn Vadhán into a Primaris Marine of the Emperor's Spears.
- Sergeant Morcant - Morcant of the Arakanii tribe is a battleguard of the Emperor's Spears' 3rd Warhost.
- Sergeant Faelan (KIA) - Faelan of the Kavalei tribe was a battleguard of the Emperor's Spears' 3rd Warhost. Faelan lost much of his face in battle and then had much of his head replaced by cybernetic prostheses. He was killed by a child Rogue Psyker of the Exilarchy when the Chaos Space Marines of The Pure boarded the strike cruiser Hex. His gene-seed and Astartes organs were later used in the process to turn Vadhán (formerly Lieutenant Commander Amadeus Kalus Incarius) into a Primaris Marine.
- Connall - Connall of the Kavalei Tribe was killed during the Battle of Akamakar.
- Vadhán (formerly Lieutenant Commander Amadeus Kalus Incarius) - In the wake of the Great Rift's birth, Amadeus Kalus Incarius of the Mentors Chapter was sent to the region of Elara's Veil by the command of the Indomitus Crusade to determine if the Space Marine Chapters protecting that portion of the Emperor's realm -- the Emperor's Spears and the Celestial Lions -- remained loyal. In the course of aiding the Emperor's Spears in fighting off the forces of the Chaos Space Marine warband known as The Pure and their horde of Exilarchy Chaos Cultists and mutants, Incarius was so badly wounded that his body would have needed to be largely replaced with bionics. To save his life, he instead underwent the transformation wrought by the Rubicon Primaris, and became a Primaris Marine. In the end, learning that the Inquisition was still pursuing a vendetta against the Celestial Lions Chapter and that the Warp storms unleashed by the Great Rift had cut Elara's Veil off from the rest of the galaxy, Incarius chose to join the Emperor's Spears Chapter. He took the new name of Vadhán or "False Scorpion" in the dialect of the Vargantes tribe of the Emperor's Spears' homeworld of Nemeton. The name was chosen for him because the Mentors had taken on the colours and Chapter number of the Star Scorpions, the Emperor's Spears' former allies, whose Chaos-corrupted remnant had become The Pure.
Non-Astartes Personnel
- Anuradha Daaz (Helot) - Anuradha Daaz was a "helot", or Chapter serf, in service to the Mentors Chapter. She accompanied Lieutenant Commander Amadeus Kalus Incarius on his mission into Elara's Veil and played a major role during the events in which her master had a central role. Daaz followed Incarius into service with the Emperor's Spears Chapter and served both well into her old age.
Chapter Relics
- Beast-Hide Cloak - When a mighty beast stalked a tribe on Nemeton, an Emperor's Spear Astartes returned to his people, who believed him to be a ghost, and set out into the wilds to end its scourge. The "ghost" returned with the slain beast and delivered it to the tribe to symbolise the end of their suffering. In return, the tribal elders bestowed a portion of its hide in recognition of the ghost's grim service, which has since become a treasured relic of the Chapter.
- Druidic Talisman - Librarians, Techmarines, Apothecaries and Chaplains of the Emperor's Spears diverge from the Codex Astartes to become Druids. The most esteemed mark their black power armour with sigils and totems earned through bloodthirsty duty to the Chapter.
- Horizon Blade - Blue waves of energy seemingly cascade in the alloy of this relic Power Sword, their ceaseless motion intensified by the movement of the bearer. As they crash across its length, its lethal edge is energised to levels capable of cutting anything it comes into contact with.
Chapter Fleet
- Daughter of the Storm (Unknown Class) - The Daughter of the Storm is a warship of the Emperor's Spears.
- Hex (Strike Cruiser) - The Hex is a strike cruiser of the Emperor's Spears' 3rd Warhost.
- Skyreaver (Unknown Class) - The Skyreaver is a warship of the Emperor's Spears' 6th Warhost.
- Warrior Queen (Battle Barge) - The Warrior Queen is the flagship of the Emperor's Spears.
Chapter Appearance
Chapter Colours

The Manticora Bestia Fidelitas, a sigil which represents the unity of the three Chapters of the Adeptus Vaelarii.
The Emperor's Spears primarily wear sky blue power armour and a white helm. This Chapter does not display company numbers on its power armour, and it does not paint the trim of its shoulder plates to designate company. Squads are marked with Nemetese runes or High Gothic numerals on the shoulder pauldrons or greaves to indicate their identity.
Nemetese runes look similar to Ogham, an early medieval runic alphabet used to write the early Irish language on Old Earth. Outsiders cannot penetrate the meaning of these specific symbols, but they are never used elsewhere in the Nemetese tongue, and do not seem to be numbers.
Most warriors bear personal heraldry on one knee plate, which is painted in a deeper blue. This heraldry usually reflects a specific campaign the battle-brother fought in, or the Manticora Bestia Fidelitas, a sigil representing the unity of the Adeptus Vaelarii. The Skitarii of Bellona and allied Astra Militarum regiments often also bear this sigil. Many Emperor's Spears wear cloaks made from the hides of beasts they have hunted and slain on Nemeton.

Warriors of the Emperor's Spears' Veteran 1st Company, "the Paragons," have the trident marking on their helms and white shoulder pauldrons, while maintaining the standard sky blue trim. Many of the Paragons also have the trident symbol tattooed on their faces, in red or white ink. Officers from all companies may choose to paint one or both shoulder pauldrons white.
The colour of the right knee guard is dark blue, almost black, and is used for personal heraldry. Many Emperor's Spears have the sigil of the Sentinels of the Veil placed there, denoting them as the warriors chosen to watch over the region of the Ultima Segmentum called Elara's Veil. This symbol takes the form of the red and black sub-sector symbol which depicts Elara's Veil on Imperial stellar cartographic maps, for example, or it can be a personalised symbol of the nebula itself. This is similar to the way the Astral Claws, Lamenters, Mantis Warriors, and Charnel Guard wore the unique marking of the Maelstrom Warders to designate their role as sentinels over the Warp rift known as the Maelstrom.
Many Veteran members of the Emperor's Spears have the symbol of the Star Scorpions displayed on the right knee guard instead to reflect the campaigns they fought alongside their lost sibling-Chapter. Obviously, their newly-arrived Primaris Space Marine brethren do not display these symbols. Other Emperor's Spears Astartes, including the Chapter's Primaris brethren, often have the Celestial Lions' symbol engraved on their right knee guard, reflecting the many Imperial Crusades the Emperor's Spears fought alongside the Lions.
Another common symbol displayed on the Emperor's Spears' right knee guard is the Argent Gauntlet, which is worn by warriors from both the Celestial Lions and the Emperor's Spears and takes the form of a silver fist. This is the symbol of the Exodus Armada. Any warrior of any rank is authorised to wear it, so this, or the symbol for the Sentinels of the Veil, is often the default icon that is displayed on the right knee if the warrior makes no other choice.

Emperor's Spears' sergeant's helm with transverse red crest.
The non-commissioned and line officers of the Emperor's Spears sometimes make use of helmet plumes. Sergeants can wear red transverse (side-to-side) crests, similar to the ones worn by the ancient Space Marine Legion Centurions of the Great Crusade era. Veteran sergeants wear red-and-black striped transverse crests. Lieutenants have red-and-black striped longitudinal crests (front-to-back) while captains wear white longitudinal crests. While most officers of the Emperor's Spears wear helm crests, others use the standard helms and helm colours proscribed in the tenets of the Codex Astartes, similar to the Ultramarines.

The "Druids" or "War-Priests" who take the place of standard Librarians, Techmarines, and Chaplains in the Emperor's Spears hierarchy all wear black power armour, with druidic and priestly elements adorning their battle-plate. Druids who replace Techmarines wear black as well, and they use the standard Techmarine armour technology, but without the druidic and priestly elements.
Unusually, the Emperor's Spears' Techmarines don't wear many symbols of Mars. Instead, they opt to display the icon of the nearby Forge Moon of Bellona, which takes the form of a halo (a half-cog) over a skull weeping blood. This is the same symbol used by the Cult Mechanicus and Skitarii Legions of Bellona (mostly black with red patches).
The Druids who serve as Librarians, Apothecaries and Techmarines have white helms, and the few that have also served in the Veteran 1st Company of the Paragons possess the red trident on their helm. The Druids who take the place of Chaplains wear the traditional black battle-plate with bone-white helms. Red tear-trails are carefully applied to the skull-mask's cheeks, as if weeping. Any skulls that are displayed on their armour also have these same blood-tears, which represent some unknown meaning from Nemetese legends.
Space Marines from the Emperor's Spears have also been known to wear trinkets, talismans, serpent scale-hides and fur pelts. These are usually gifts from the Twelve Tribes of Nemeton, not things the Astartes have hunted or made for themselves.
These primitive animistic fetishes are nowhere near as common as they are on the Space Wolves' wargear, but appear very similar to those worn amongst the Space Marines of the Salamanders Chapter. The most common ornamentation worn by the Emperor's Spears are Nemetese runes on their armour, which are usually black, silver, or white -- either painted or carved into talismans.
Each warhost of the Chapter marks their azure armour with a range of Nemetese Ogham runes that are believed to comprise a mix of unit markings, honour sigils and other, more esoteric tribal icons.
The Emperor's Spears have codes of conduct that forbid them from becoming too filthy. Even in the middle of a campaign, they are forced to maintain their armour as well as they can, to respect its Machine Spirit and to intimidate the enemy, rather than looking battered and therefore weak.
Chapter Badge
The Emperor's Spears' Chapter badge is a black trident pointed upward with a white skull centred upon it, all centred on a field of sky blue.
