Consul - Consul Types: The following are some of the more common examples of Consuls found in the Space Marine Legion forces of the Great Crusade and Horus Heresy, although many others existed in particular Legions:Armistos - Few individuals were capable of the unending operation of maintaining, categorising, requisitioning and dispensing the vast arsenals of an entire Space Marine Legion. Beyond this, many such officers of the Legions worked to improve the weaponry at their disposal, running simulations and field tests of augmented weaponry. The logistical skills of a quartermaster required of an Armistos were much sought after by the Legion's Master of Arsenal, particularly in those Legionaries with a level temperament who were not apt to charge into the fray but were capable of supporting and supplying their battle-brothers without desire for aggrandisement.Champion Consul - A Legion Champion's sworn task was to hunt down and slay the commanders and heroes of an enemy force in single combat. Armed with the finest weapons available, these deadly warriors embodied the honour of their Legion.Loyalist Champion Consul - Chosen from the best blades of the Legion, a Champion bore the honour of their chapter or company in battle, and was armed and armoured in the finest panoply of war. Their sworn task was to seek out the foe's mightiest warriors, and slay them in glorious single combat. Such victories were a crushing blow to enemy morale, and an object lesson in their Legion's superiority. A Loyalist Champion Consul was a skilled duelist -- armed with a massive two-handed Paragon Blade, with a Combi-melta at their side. Their finely-wrought Artificer Armour often featured a flowing tabard, as well as a knightly gorget to guard against return blows. Medallions and decorative chains proclaimed the Champion's many victories, marking him as a foe worthy of any challenger.Traitor Champion Consul - Those Champion Consuls pledged to the Traitor Legions were largely identical in fucntion to their Loyalist brethren save that they took great pleasure in cutting down any Loyalist lapdogs foolish enough to stand in their way. A Traitor Champion Consul was a paragon of martial expertise and an expert in the art of dealing death to the followers of the False Emperor. They were armed with a deadly Paragon Blade for parrying blows and lopping off Loyalist heads while wielding a Volkite Serpenta to melt through enemy armour at range. The bulky and tough Artificer Armour worn by a Traitor Champion was multi-layered, given even more protection, and was often adorned with the icon of the Eye of Horus, so there was no mistaking as to whose cause they fought for.Chaplain - The Chaplain Order, established towards the end of the Great Crusade on the advice of the Word Bearers, was intended to create a cadre of fearsome veteran Astartes warriors who would enforce a cohesion of doctrine and belief in the scattered and increasingly idiosyncratic Legions, far from Terra. Theirs was a mortuary symbol of sacrifice graven in the form of an ornate staff, mace or axe: the Crozius Arcanum, which served as both a badge of office and a deadly weapon.Legion Delegatus - A Legion Delegatus was a mid-ranking Legion officer, such as a Centurion, tasked with a specific mission by their Legion high command and formally deputised to act in all matters with the full weight of their commander's authority. As such, they could mobilise the Legion's resources to the full, deploy its assets and, if performing a mission of vital strategic worth, assemble a strike force of chosen warriors.Legion Esoterist - The Legion Esoterists were a late creation among many of the armies embroiled in the Horus Heresy, as members of the Librarius returned to their studies in violation of the Decrees of Nikaea with or without the blessing of their primarchs, and delved into the forbidden lore that saw common use on the battlefields of that dark age. Some Esoterists studied the Warp with the sole intent of discovering the weakness of those entities that dwelled within. They were dedicated wholly to the study of the Warp and its denizens, seeing them as tools for the prosecution of war, unburdened by loyalty or purpose. If they could chain them to the cause of their master, then they would gladly sacrifice their sanity in pursuit of victory. Esoterists mastered the sealing of ætheric energy and investigated any method of repelling the foul entities that spilt from that realm, no matter how strange or ritualistic such arcane tricks might be. Though those battle-psykers who had received real training might scoff at their dubious rites, few could deny their effectiveness in battle against the forces of Chaos.Legion Forge Lord - Masters of the machine and foundry, Forge Lords were the most experienced and skillful of the Legion's Techmarines. These warrior-smiths were skilled battle-leaders as much as they were artisans of war, and were often appointed to the command of Legion detachments comprised largely of tanks and armoured vehicles or Battle-Automata, as well as serving as stewards to a Legion's Dreadnoughts.Herald -  A Herald was an officer of consul rank who carried the standards and other sacred totems of their Legions, chapters, companies and other organisations. As the wars of the Horus Heresy spread to consume the galaxy, billions fought and died under the banners of warlords they had never seen or heard firsthand, and even among those such as the Legiones Astartes, near-religious fervour became common for those artefacts touched by primarch, Warmaster or Imperial Regent, and given to a chosen emissary as a sign of authority and favour. The Blackshields, having obscured their heraldry or cast aside former masters, were no different, their strange sigils or blackened flags becoming totems of destruction and the foresworn.Librarian Consul - For many years the Legions maintained cadres of Astartes battle-psykers in their ranks, warriors who fused these esoteric powers with a Space Marine's transhuman physical power. But many within the Imperium's hierarchy were troubled by such dangerous and unstable potential, and after dark events in the Great Crusade's later period, such adepts were forbidden from the use of their arts and arcane lore by the Emperor Himself at the Council of Nikaea.Master of Signal - A vital link between those desperately fighting and support elements of the Legion in battle, the Master of Signal was a strategic and communications specialist capable of interpreting and directing the flow of battle around them and calling in support strikes from distant batteries and orbiting vessels. A Master of Signal was commonly attached to the forward elements of a Space Marine assault, providing vox and cogitator communications support across the wider warzone, and was capable of calling down a pinpoint bombardment from either orbiting fleet assets or static artillery positions nearby, engulfing the foes of Mankind in flaming destruction.Moritat - Said by some to be no less than death incarnate, and by others to be dishonourable murderers with no place in the Imperium's order of battle, Moritats were lone killers operating outside their Legion's usual command structures at the behest, or at least sufferance, of its high commanders. Regarded usually as dangerously unstable outcasts -- perhaps created by some seldom-exposed flaw of gene-seed or indoctrination -- they were also savage and proficient warriors, however, having become one with the act of killing, honing their transhuman reflexes to gun down the foe at close quarters to a preternatural degree.Legion Mortifactor - A specialised subset of Techmarines, Mortificators were ultimately responsible for the Legion's honoured dead known as Dreadnoughts, the furious Ancients entombed within cybernetic sarcophagi that slumbered in the Legions' sepulchres, and showed a near-fanatical devotion to their charges, in some cases going so far as to contravene the tenets of the Mechanicum adopted by the Legions' Forge Lords. A Mortificator's primary duties included the protection during slumber and rousing during war of their Legion's complement of Dreadnoughts, and when necessary, extended to the controlling of those Dreadnoughts too long asleep or too choleric to be considered wholly sane.Consul Opsequiari - The Consul Obsequiari was a battlefield overseer, granted the power of life and death over his brothers. During the Terran Wars of Unification and the early years of the Great Crusade when the Legionaries of the newly formed Space Marine Legions were introduced to the Imperium's fighting forces, certain less-disciplined and more violent Space Marine Legions such as the VIth, XIIth and XIVth Legions experienced issues with Legionaries who were bellicose, hot-tempered or often proved fractious. To help curb their worst excesses and to ensure discipline was maintained on the field of battle, a new class of disciplinary officers was created -- the Consul Obsequiari. These Disciplinary Corps served to maintain order in the ranks of the Space Marines, both during and away from battle, as well as curb any attempts to disregard or circumvent orders. The Consul Opsequiari were selected from among the most stable of the veterans of their Legion and granted the power of life and death over their brothers. Clad in utilitarian storm cloud grey power armour bare of any ornamentation, save a squad symbol on their breast and a Terran Raptor Imperialis ornament, these officers carried out their solemn duty within the ranks of the Legion. To single them out on the field of battle these individuals were also marked by the distinctive emblem of that oft-maligned order, stencilled upon their right pauldron and the abdominal buckle of their armour. Reorganisations and the changes in Legion culture made upon the reunification of these Legions with their respective primarchs ultimately made this position obsolete before the onset of the Horus Heresy.Legion Pathfinder - Within the ranks of the Legions at the time of the outbreak of the Horus Heresy there were few remaining Scout Marine cohorts, with most companies equipped with the Scout Armour long since reassigned to Recon detachments. Those few that remained were often veterans of over a standard century of war in the most hostile terrain known to Humanity, and the last Pathfinders were the unchallenged experts on combat within such dangerous ground.Legion Consul Praevian - A Legion Consul Praevian was the keeper of the Legion's bound Battle-Automata, those soulless machines sworn to the Legion's service and inducted into their ranks as honourary Legionaries after solar decades of service, a practice that increased as the Horus Heresy inflicted an ever-greater death toll on many Legions' ranks. Initiated into the rites of the Mechanicum to a lesser degree, these officers oversaw the maintenance and programming of their charges and ensured that loyalty to the Legion and its traditions were enshrined in their core logic. On the field of battle, they marched at the forefront of the inducted maniples, guiding them in the correct prosecution of war and acting as examples of true sons of the Legion. Often chosen from amongst the ranks of those veterans whose injuries had required extensive augmetic rebuild and left them ill-suited for other, more specialised roles, these warriors were often solitary individuals, given to brooding and keeping to the company of their iron brothers. It was rare in most Legions for these warriors to advance higher up the chain of command, and some Legions used the rank as a dumping ground for those deemed unfit for other duties, while others, most notably the Iron Hands and Salamanders, considered it an honour to serve with such unique avatars of the Machine Cult's craft.Primus Medicae - High officers of the Legion Apothecarion, the primus medicae of a Legion held the onerous duties of both ensuring the battle-readiness and physical wellbeing of their battle-brothers. This was an authority which none but a primarch or his chosen deputy could overrule, and such warriors were dedicated to preserving the gene-seed of the Legion from loss or contamination at any cost, even that of their lives. The primus medicae were skilled in all the fields of medicae relevant to the biomedical care of Astartes on and off the battlefield and the creation of new Space Marines for the Legion using the accelerated maturation techniques in use at the time of the Great Crusade.Primus Nullificator - With the increase of uncontrollable occurrences of Daemonic incursion across the galaxy, many officers within the Legiones Astartes on both sides of the conflict resorted to arcane and superstitious means to counter the little-understood threat of the Empyrean. These pioneers sanctioned research into esoteric artefacts and weapons and openly sought prohibited lore in the hope that it would provide wisdom capable of combatting the galaxy's intangible horrors. These officers, who were first among the Nullificators, forged an example and encouraged those serving under them to also seek out by any means necessary the answers to defeat the arcane threat.Siege Breaker - The wreckers of cities, the bringers-down of fortress walls and the shatterers of strongholds, Siege Breakers were officers of the Legion whose tactical speciality was precisely applied destruction against strategic targets. Placed often in command of armoured spearhead assaults and frontline artillery units, they preferred to closely observe their work, rather than sit back behind the lines, and so were deadly efficient in adapting their force's attack patterns from moment to moment.Vigilator - Highly skilled as watchers and hunters among their brethren, Vigilators were the eyes of their Legion on the ground, their wisdom paramount in scouting out the foe's disposition and strength, and determining the best place to strike. Theirs also were the arts of sabotage and assassination, and while some Legions were more inclined to such subtleties than others, all saw their military value.Warmonger - In seemingly every Legion, there was a cadre of Centurions who competed for the honour to make first contact with any enemy force or lead the spear-tip of any assault. These hardened line commanders were much respected for their willingness to heroically throw themselves and their soldiers into the toughest resistance and were entrusted to prosecute shock assaults which crushed a foe in a single action, breaking its lines of supply and leaving its defences in disarray. To these warriors, the informal honorific "Warmonger" was attributed, and any who were marked as such were destined for greatness in their Legion, rapidly rising in stature and rank, should they survive.
