While the Adeptus Mechanicus is a part of the Imperium, it has developed separately and enjoys a considerable degree of independence. Due to the great amount of power it wields, the Adeptus Mechanicus is more like an allied empire than an organisation within the Imperium. The Adeptus Mechanicus also follows a different religion from the rest of the Imperium. The religion and religious structure of the Adeptus Mechanicus is known as the Cult Mechanicus.
The symbol of the Adeptus Mechanicus is a skull, half-bone and half-machine, set against the background of a black and white cog.
Adepts of the Adeptus Mechanicus are known as tech-priests. Any member of the Cult Mechanicus over the rank of menial will often be referred to as a tech-priest, though Magi and higher ranks are usually referred to by rank.
As befits the religious nature of the Mechanicus, tech-priests usually wear robes, which are usually either rust-red or white. Tech-priests are often cybernetically augmented. The level of a techpriest's augmentation is highly dependent on his rank within the Cult Mechanicus; a novice may have only one or two augmented systems, if any, while very senior members may have only a few biological organs left in their bodies.
Adeptus Astartes
[+2 to Strength, Constitution | 6000 Starting Credits | Gains two combat abilities | Starts with 3 Frag Grenades| Starting Stats - Str: 6, Con: 6, Agi:5, Wil: 5, Luc: 4, Int: 5, Cha: 5]
The Adeptus Astartes (commonly known as Space Marines, and colloquially as Angels of Death) are the most elite and feared fighting forces of the Imperium. The primary unit of organization is the Chapter, a self-contained army fully equipped with its own transport, non-combatant support staff, etc. There are around a thousand Chapters, each comprising a thousand Space Marines. There are far too few Space Marines to form the Imperium's main military forces; instead they operate as highly mobile strike forces. They are entrusted with the most dangerous missions, such as lightning raids behind enemy lines, infiltration, and tunnel fighting6. Through selection, training, and conditioning, Marines are physically, mentally, and spiritually superior to any other Imperial soldier.5
Adeptus Astra Telepathica
[+2 to Psyche, Willpower | 5000 Starting Credits | Is a Psyker | Starts with 3 Powers| Starting Stats - Str: 4, Con: 4, Agi:5, Wil: 6, Luc: 5, Int: 6, Cha: 5, Psy: 6]
The Adeptus Astra Telepathica is divided into a recruitment body (the League of Blackships) and a training body (the Scholastia Psykana). These two are united under the Master of the Adeptus Astra Telepathica and his advisory council of several hundred senior officials from the two divisions. They are responsible for the specially trained Astrotelepaths who use their mysterious powers to communicate with others of their kind across vast interstellar distances which separates the worlds of the Imperium.5-p94 Their ranks consist of psychic servants of the Imperium and these psykers have undergone the Soul Binding ritual with the Emperor. This process passes on some of the Emperor's strength of will into his servant thus protecting him from evil, psychically attuned enemies. The ritual ultimately results in blindness though there is a rare few Astropath's who are judged strong enough to warrant them not taking part in the Soul Binding with these individuals considered the lucky ones as they do not have partake in the agonising process that most Astropath's must follow. It is through the righteous persecution of the Inquisition combined with the careful testing of the Coven Masters of the Adeptus Astra Telepathica which purges any deviant mutations that are commonly associated with those beings that develop psychic potential.
Adeptus Ministorum
[+2 to Charisma, Willpower | 6000 Starting Credits | Can Obtain Priest Points | Starts with 5 Prayers (Unless stated otherwise) | Starting Stats- Str: 4, Con: 4, Cha: 6, Luc: 5, Wil: 6, Int: 6]
The Ecclesiarchy (officially the Adeptus Ministorum) is the only official state church of the Imperium. It maintains and spreads the Imperial Cult throughout the Imperium. Although the interpretation of particular Imperial Cult dogmas varies through the Imperium, any extreme deviance from its strictures is considered heresy and dealt with great severity. The Ecclesiarchy is based on Terra, its urban palace covering nearly all of the southernmost continent.
