Orks are seen by their enemies (pretty much everyone else in the galaxy) as savage, warlike and crude, but they are one of the most successful species in the Milky Way, outnumbering possibly every other intelligent race, including Mankind.

However, the power of the Ork race as a whole is limited due to the fact that they are split into hundreds of tiny empires, klanz and tribes, which are more often warring between themselves than not. Were the Orks ever to unite as a species, they would undoubtedly crush all opposition in a massive migration-invasion known as a WAAAGH!.

A Chaos Daemon, or simply Daemon, also known as a "Neverborn" amongst the forces of Chaos, is an intelligent and usually malevolent entity of the Warp comprised of purely psychic energy. Daemons are sentient embodiments of Chaos and collectively the greatest servants of the Chaos Gods and of Chaos itself as a universal force.

Daemons are created at the whim of one of the four major Chaos Gods from a fraction of the god's own power within the Immaterium and act as an extension of its will. A Daemon's appearance and intrinsic character reflect the god's own nature. These Daemons may be reabsorbed into the god's psychic signature in the Warp at their whim.

The Deathwatch, known also as the "Long Vigil," and the "Long Watch," is a unique Chapter of the Adeptus Astartes comprised solely of Veteran Space Marines that serves the Ordo Xenos of the Imperial Inquisition as its Chamber Militant. They are the warriors of last resort when the Inquisition needs access to firepower greater than that which the Astra Militarum or a team of its own Acolytes or Throne Agents can provide.

It is the sacred task of the Deathwatch to stand sentry against all of these terrible xenos races and many more besides. They are ready to act when such ancient evils rise to threaten Mankind once more. The Space Marines of the Deathwatch form the first, and often only, line of defence against these inhuman horrors.

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.

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 mortals who wield the corrupt power of the Chaos Gods. They were created by the Emperor 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. They have the honour of being implanted with gene-seed engineered directly from the genome of the Emperor Himself.

Unlike other Astartes, every Grey Knight is a potent psyker. Yet, in the 10,000 standard years of Imperial history, no Grey Knight has ever been corrupted by the Ruinous Powers of Chaos. Additionally, the Grey Knights do not follow the tenets of the Codex Astartes in the matter of force organisation.

A Hunter Cadre is the Tau terminology used to indicate what the Imperium of Man would call a company of soldiers. The Tau were once a species of hunters and gatherers and the Tau who now make up what is the T'au Empire's Fire Caste were the most-skilled hunters of that ancient time.

Even though the Tau are now a xenos species gifted in some areas with technology that is more advanced than that available to Mankind, the Tau Lexicon still makes use of much terminology derived from their hunter-gatherer period and companies of Tau warriors are always referred to as Hunter Cadres in the Low Gothic translation.

A Hive Fleet is a large armada of living, biomechanical starships created by the Tyranids for the purpose of gathering the raw materials and biomass necessary for the reproduction, evolution and expansion of their species. A hive fleet is used to attack and strip star systems of their biomass using the full range of Tyranid bioforms.

Terminators are Space Marine Veterans who have earned the right to wear Tactical Dreadnought Armour, better known as Terminator Armour. They are their Chapter's greatest infantry assets, each essentially serving as a walking tank.

Tactical Dreadnought Armour combines the technological developments of power armour with the sealed environmental suits designed for starship crews that work in highly unstable or corrosive environments such as inside the high pressure casings of Plasma Reactor shields. It can even withstand the colossal impact of high speed orbital micro debris.

The Adeptus Custodes, known as the Legio Custodes during the Great Crusade and Horus Heresy eras, is the Imperial adepta responsible for protecting the Imperial Palace and the physical body of the Emperor of Mankind, as well as serving as His most important emissaries, His companions, and the keepers of His many secrets.

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.
