Name of nation: The Ruinous Powers
Species: multiple corrupt species, Daemons, other warp entities
Description of government: Primarily Anarchy. Meritocracy. Direct control from religious deity.
Description of military:
The forces of Chaos do not act as a cohesive military forces rather as bands of Pirates and Marauders. The largest standard force is a Warband or Legion which generally consist of a large fleet or even control of planets. There are times when a black crusade is called at which point forces from all Chaos subfactions unite under a single banner for some time.
Primary tactics used by Chaos are trickery and shadow play instead of direct fights.(unless referring to warriors of Khorne)
Technological Overview: Due to the nature of Chaos their Technology largely consists of stolen/pirated tech. They do however produce some of their own equipmet.
The warp drive is the single most important Chaos technology as it allows direct access to the warp.
Cultural Overview:
Chaos, also known to its servants as the Primordial Truth or the Primordial Annihilator is the universal and usually malign spiritual force embodied by the malevolent intelligent entities comprised of psychic energy that live in the Warp. Chaos is the equal and opposite of Order. The entities who embody Chaos are mostly daemons, but the term also encompasses those mortals who have thrown in their lot with Chaos, ranging from simple peasants and/or labourers who serve as Chaos Cultists, to Traitor Soldiers, planetary militia, nobles, Planetary Governors, and the mighty Chaos Space Marines and Traitor Titan Legions of the Dark Mechanicus.
Chaos is also itself the turbulent psychic energy that comprises the Immateriumand gives shape to the nightmare domains of the individual Chaos Gods that are collectively called the Realm of Chaos. Chaos is almost synonymous with the Warp -- the two concepts are inseparable, for Chaos is the limitless ocean of spiritual, psychic and emotional energy that defines the Immaterium and underlies the 4-dimensional material universe of space-time. It is a great and raw force of change and power, and is both physically and spiritually corrupting, though it is not in itself necessarily "evil." While its adherents and servants act in ways that are often malevolent, some devotees of Chaos are more dedicated to the service of freedom and change than of the pure selfishness that Mankind and most other intelligent species define as nefarious. However, more often than not, the Chaos Gods reward individual accomplishment in such a way that the ends justify the means, and the absence of hierarchy and emphasis on individual freedom leads to the pursuit of excess and personal aggrandisement that can only be characterised as damnation.
The most evolutionarily-advanced mortals, psykers, can utilise this energy, thus making them capable of abilities which transcend the standard physical laws of the material universe as humanity understands them. However, the malevolent power of Chaos can gradually corrupt a psyker, tainting his mind and body and turning him into the slave of the Ruinous Powers. The most powerful entities of Chaos are the four great Chaos Gods, also known as the Ruinous Powers, who each embody one aspect of the greater force of Chaos and can be worshipped individually or as an entire pantheon. The iconic symbol of Chaos is the eight-pointed star, representing the infinite possibilities of Chaos. Ultimately, Chaos and its entities seek nothing less than the complete destruction of the material universe and its hated Order, so that all of Creation is once more consumed by the primordial and uncontained energies of Chaos. In general, Chaos is a malevolent spiritual force that represents the collective negative aspects of the psyches of every sentient being in the Galaxy, and in the wider universe. The Chaos Gods embody myriad and particular flaws of a vast collection of races.
Chaos corrupts so easily because it speaks to the character flaws inherent in every man and woman and seeks to exploit the weaknesses of their respective natures. It takes an extraordinary individual of truly iron will and selflessness to resist the serial temptations of Chaos. It is also these inherent character flaws that produce the rampant physical and anatomical mutations of individuals exposed to Chaotic energies, as these mutations are driven by the inner flaws of the person's psyche being made manifest in their physical person as Chaos bridges the gap between the Immaterium and realspace.
With all the obvious dangers associated with Chaos, such as mutation, daemonic possession, and spiritual damnation, some might wonder why anyone would willingly choose to serve the Ruinous Powers. The answer is actually simple. Chaos judges its servants solely on their abilities and their records of success and failure in promoting the agenda of the individual Chaos Gods and of Chaos Undivided as a whole. Chaos also offers those who serve it the opportunity to perhaps one day wield power and respect far beyond the dreams of most mortals' avarice. For so many people, connections and inherited wealth are rewarded rather than ability, and where it is impossible on many worlds for a talented individual to ever better their lot, Chaos actually offers a substantial degree of freedom and the only real meritocracy that they have ever known. But Chaos is not a benevolent force, and for the vast majority of those who fall to Chaos' temptations, they will never reach either power or position and will be little more than faceless puppets in the endless schemes of the Dark Gods. While Chaos may reward success with power, even the mightiest Chaotic servant becomes a slave of Chaos, never its master. Most Chaotics will fail in their quests for power, eventually ending up as possessed Daemonhosts, mindless Chaos Spawn, or simply as just another corpse in the heap, a pawn whose usefulness to the Ruinous Powers has ended.
History:
Chaos has yet to be encountered by anyone within this Universe. It's existence is know to the more enlightened and it's coming has been fortold by some.
Other:
Warp taint affects all races on a small scale unless that race is using mind control of some kind. And even they Psionic units can be possessed by Daemons.
Warp space is not accessible without a warp drive. Note: A Protection field is recommended to defend against warp entity incursion but not required for warp travel.
Chaos gods cannot enter combat physically but also cannot be destroyed. They can However be weakened.
Many religions believe Chaos to be Hell or other evil forces out of misunderstanding thus if you wish to incorporate chaos into your religion feel free to.
The 5th Chaos god know as Malal or Malice is the Rogue god working to destroy both Chaos and the Material world. I will roleplay his existence and work against myself at times.
The worship of the gods is not limited to actual worship. For Example The spilling of Blood is still giving homage to Khorne.
