The Imperium of Man is a galaxy-spanning interstellar Human empire, the ultimate authority for the majority of the Human species in the Milky Way Galaxy in the 41st Millennium A.D. It is ruled by the living god who is known as the Emperor of Mankind.
The founder and ruler of the Imperium is the god-like Emperor of Mankind, the most powerful Human psyker ever born. The Emperor founded the Imperium over 10,000 Terran years ago in the late 30th Millennium during the Unification Wars on Old Earth following the terrible period in Human history known as the Age of Strife.
The Adepta Sororitas, colloquially called the "Sisterhood," whose military arm is also known as the Sisters of Battle and formerly as the Daughters of the Emperor, are an all-female division of the Imperium of Man's state church known as the Ecclesiarchy or, more formally, as the Adeptus Ministorum.
The Sisterhood's Orders Militant serve as the Ecclesiarchy's armed forces, mercilessly rooting out spiritual corruption and heresy within Humanity and every organisation of the Adeptus Terra.

There, the bold Rogue Trader seeks to eclipse the rich history of her ancestors with her own rise to glory - or die trying.
Rogue Traders are natural-born leaders, merchants of death and talented explorers with a keen eye for profit and survival. Each carries an heirloom Warrant of Trade. This priceless and sacred item, as individual in form as the Rogue Trader themselves, entitles them to travel beyond the boundaries of the Imperium - into dangerous wilderness space, regions controlled by secessionists and xenos, or even beyond the fringes of the galaxy itself.
The Adeptus Arbites are the police force of the Adeptus Terra, devoted to enforcing Imperial law throughout the entire Imperium. Utterly dedicated and without mercy, the Arbites are feared throughout the galaxy, for they are the agents of a harsh law, where failure and incompetence are crimes, and the only punishment is death.
Arbites are empowered to act as judge, jury and executioner – citizens have no rights, and only members of the Priesthood of Terra or the Inquisition could claim anything so elaborate as a trial.
The Adeptus Mechanicus is the official Imperial name within the Adeptus Terra for the Cult Mechanicus or Cult of the Machine based on Mars which provides the Imperium with its scientists, engineers and technicians.
The tech-adepts of the Mechanicus are the primary keepers of what is viewed as sacred wisdom, a privileged caste of Tech-priests who jealously guard the knowledge required to maintain and construct much of the Imperium's advanced technology.
The Grey Knights are a secret and mysterious Chapter of Space Marines specifically tasked with combating the dangerous daemonic entities of the Warp and all those who wield the corrupt power of the Chaos Gods.
They were created by the Emperor Himself with the aid of Malcador the Sigillite at the time of the Horus Heresy to serve as Humanity's greatest weapon against the threat posed by the existence of Chaos.
Hearthkyn Salvagers are elite teams of Leagues of Votann Hearthkyn Warriors who serve as scouts, explorers and technology salvagers. They have been specially trained to extract prized artefacts and locate precious strategic resources within the depths of space hulks and other voidship wrecks.
Years of hard-won experience have taught the Leagues many lessons about the dangers of space hulks, and the specialised equipment carried by Salvager teams is a testament to how well they have prepared for unexpected challenges.
The Skitarii (sing. Skitarius), also known as the Tech-Guard and the Legiones Skitarii, are the cybernetic military forces of the Adeptus Mechanicus of the Imperium of Man.
To a man, the Skitarii are warriors born. They take pride in their holy work, glorying in the power of the Omnissiah as He drives them to ever greater feats. Reticules and calibrators pick out targets with uncanny accuracy, Galvanic Rifles bark and servitor-bullets find the skulls of the foe.
The Astra Militarum, also known as the Imperial Guard in colloquial Low Gothic, is the largest coherent fighting force in the galaxy. They serve as the Imperium of Man's primary combat force and first line of defence from the myriad threats which endanger the existence of the Human race in the 41st Millennium.
It is comprised of countless billions of men and women -- hundreds of thousands of different regiments, supported by a vast array of light and heavy armoured vehicles that provide the Guard's primary offensive punch. The Astra Militarum are usually the first Imperial force to respond to a threat if a world's Planetary Defence Force (PDF) fails to suppress it.
The fighting men and women of the Imperial Navy are called upon for many tasks, from garrisoning void ports to escorting the Navigator elite. The bravest and most daring of their ilk are selected for the Breacher teams – the blunt hammer at the head of a Navy boarding assault. Trained in close-quarters combat and equipped with a range of specialist equipment, these bold boarders smash apart anything in their way under a hail of shotgun fire, grenades, and axe blows.
Split into three main orders or "ordos majoris," the Ordo Xenos (Alien Hunters), the Ordo Malleus (Daemonhunters) and the Ordo Hereticus (Witch Hunters), as well as many smaller, more specialised orders called the "ordos minoris," the Inquisition is ruthless in uncovering and snuffing out Chaos corruption, heresy, and mutation wherever they may be found among the million worlds of Mankind.
The relentless and deadly agents of the Inquisition have infiltrated every facet of Human society to ensure that Chaos can never again take root in the Imperium, and that no alien race will replace Humanity as the dominant intelligent species of the Milky Way Galaxy.
Intercession Squads are one of the most common kill teams deployed by Space Marines accompanying the Indomitus Crusade Fleets. Intended as a standard pattern for Adeptus Astartes kill teams, Intercession Squad protocols are disseminated to every fleet. These specialist groups of Intercessors and Assault Intercessors were first formulated by the Primarch Roboute Guilliman and have proven brutally effective. The Lord Commander planned them as tactically adaptable teams that could respond to the needs of all manner of missions, for even his strategic genius could not foresee all the manifold threats that the fleets would encounter out in the galaxy's darkness.
"One of their squads opened the Hargle Pass for us. Three more rescued that company of the 14th trapped on Hill 338.
A couple more destroyed eighty-three greenskin aircraft on the ground at one of the xenos' bases.
Right now, I've got about two dozen teams wreaking havoc across the battlefront.
They're killing Orks, feeding us intelligence and completing every task.
Were that I always had some of these troops to hand, the Tarnis and Lirnel III campaigns would have gone much more smoothly."
Novitiates are female Progena of the Schola Progeniums, who have been selected to undergo training to join the Adepta Sororitas. These aspirants are then given a Ring of Suffrage to wear and take the Oaths of Adherence, in order to become Novitiates.
Their training is overseen by veteran Sororitas, who ensure the Novitiates master the Adepta's fundamentals and this may last a number of years. Even if a Novitiate has already been chosen to serve within a particular Order during that time, their trainers will demand that the Novitiates know the basic skills of all of the Adepta's Orders. This is so the Novitiates can be a tool in the Emperor's hand, to either to cure, learn, counsel or kill.
Elite killers, saboteurs and terror troops who spread fear and ruin throughout the enemy's domain -- these are the Vanguard Space Marines, the first into battle and the last sight their enemies will ever see.
Precision and ruthless efficiency are the watchwords of the Vanguard Space Marines, and the silence of death is all that they leave in their wake. Performing duties ahead of the main battle line, these forward operatives sow discord and panic throughout the enemy force.
The Space Marines or Adeptus Astartes are foremost amongst the defenders of Humanity, the greatest of the Emperor of Mankind's warriors. They are barely Human at all, but superhuman; having been made superior in all respects to a normal man by a harsh regime of genetic modification, psycho-conditioning and rigorous training.
Space Marines are untouched by plague or any natural disease and can suffer wounds that would kill a lesser being several times over, and live to fight again. Clad in ancient power armour and wielding the most potent weapons known to man, the Space Marines are terrifying foes and their devotion to the Emperor and the Imperium of Man is unyielding. They are the God-Emperor's Angels of Death, and they know no fear.

The Sisters of Silence are an all-female order of Imperial Witch Hunters tasked with hunting down rogue psykers and other psychic threats across the galaxy. They also help to enforce the Imperium's rigid laws on the use of psychic powers.
A Veteran, sometimes called a Hardened Veteran, is a trooper of the Astra Militarum who has survived multiple battles and has become a skilled and efficient warrior for the Emperor of Mankind.
Veterans are sometimes assembled into what is known as a Veteran Squad to be placed within less experienced platoons or companies. Imperial Guard regiments are often called upon to fight gruelling wars of attrition lasting standard years or even solar decades.
