Editing Religion (section)

===Warhammer 40k===
* The [[Imperial Truth]] was originally the Emperor's plan on beliefs, which he and his servants propagated throughout the galaxy during the Great Crusade. Attempting to wean mankind away from Chaos and being a firm member of the "Religion is Bad" brigade, the Emperor proclaimed there are no gods, and religion had to be abolished willingly or by force while science or reason are to be used for explaining the universe and morality.  Everything transpired according to his design, except theistic religiosity in the 40k universe is the best weapon against Chaos so Emps' interstellar state atheism policy gave them a major opening.  Things went from bad to worse when people started looking up to the Emperor as a god himself, [[Exterminatus|he responded accordingly]], and the Chaos Gods got a new tool in the form of [[Lorgar]].  After the Horus Heresy and the Emperor's removal from galactic politics (and even during the Siege of Terra itself) the Imperial Truth was slowly shelved in favor of the Imperial Cult, to the point that in "present day" 40k espousing the teachings of the Truth is ironically considered heresy. Only a few practitioners of the Imperial Truth remain, most notably the Custodes and the Space Marines (both of whom know The Emperor better than anybody to worship him as a god. Plus, their religious autonomy.).
** The [[Imperial Cult]] is the present-day religion of the Imperium of Man, and is a mix of several Abrahamic Religions along with copious amounts of warmongering, fanaticism and xenophobia.  Derived from the Lectitio Divinatus penned by [[Lorgar]] pre-HH, the Cult decrees that because the Emperor is capable of all these miracles and power: he ''must'' be a god, and why you should worship and pledge loyalty to him.  Its a complete 180 from the Emperor's original teachings, and has simultaneously been responsible for damning and saving the Imperium past the clusterfuck of the Horus Heresy.  It's unknown whether the Emperor still abhors godhood and religion and would abolish it the moment he could, or if he's resigned himself to becoming the very thing he fought against for mankind to persevere in these trying times.  Whatever the case, he didn't want to be a god, but now he has no choice but to become one.
** The [[Adeptus Mechanicus|Cult Mechanicus]] (Machine Cult) is the religion of the Adeptus Mechanicus, placing a heavy emphasis on machines, viewing them as gifts from the Machine God called "The Omnissiah" Officially, the Omnissiah is The Emperor, which allows the Mechanicus to sidestep the more puritan pundits of the Imperial Cult (we worship The Emprah, just not how you do it). Unofficially, the Omnissiah may or may not be the C'tan god: The Void Dragon. It also has a high emphasis on the collection of knowledge, and one of the Admech's roles in the galaxy is to explore remote and uncharted regions of space to find and search for knowledge that has been lost throughout the millennia. The last of these, is guidelines on machines and knowledge. Officially, heretic(tek) and xeno works are to be abhorred and disposed of, viewing them as perversions of the holy Machine God's works. Unofficially however, more liberally-minded and higher-ranked Magos would happily hoard heretek/xeno works, seeing their potential over the more restricted and constrained works of the Mechanicus.

* Chaos is a violent and complicated henotheistic (believing in multiple gods but only worshipping one) or polytheistic religion with dozens, if not hundreds of interpretations.  Even then, there's more sub-cults that worship their particular god in a specific way, either minutely or vastly different from everyone else among followers of the Big 4.  And this doesn't even get into the realm of Chaos Undivided (which worships the concept of Chaos itself, instead of the individual gods) and [[Malal]].  Chaos has very little established guidelines regarding worship, apart from their patron god's/gods' general likes/dislikes, so any religious practices or rituals are either based on commands from the god/s or up to the imagination of the cult.
** Interestingly, there is a Space Marine of the Chaos faction who follows the Imperial Truth, and that is [[Fabius Bile]].

* All Greenskins worship Gork and Mork (jury's out on whether the [[Gretchin Revolutionary Committee]] do), but are too disorganized to have anything like a formal religion, though they do make effigies of Gork and Mork and call on them.  The closest thing they have to tenants is that Gork favors violence, Mork favors cunning.  Greenskins have gotten into fights over this, but violence is part of their nature and that of their gods.  While they fight over religion, they also fight over almost any dispute anyway, and may even start a religious argument just to enjoy a good fight among themselves (though the only theological argument they can formulate is "is Gork the god of cunning or is Mork?" or vica versa). On the surface, religion does not play a big-enough role in Ork society compared to other races, being just another outlet for Orks to fight about. But if [[Ghazghkull Mag Uruk Thraka|Ghazghkull]] is any indication: religion can have a great impact on Orks, with him being becoming one of the greatest Warlords in the galaxy, primarily because he thinks he's personally blessed by Gork and Mork themselves. So if you throw in the Orks' gestalt field into the mix, its likely that its not that religion doesn't matter to them, it's under-utilized.

* The Tau's creed "The [[Greater Good]]" is a specie-wide philosophy that was adopted ever since the initial unification of the Tau in the olden days. In a nutshell, the Greater Good emphasizes the co-existence of all Tau and sapient life in general into working together for a common goal to further the Tau's progress, seeing everyone's potential and hoping to utilize that for an, ahem, greater good. Personal religion isn't forbidden, but it must not contradict or override The Greater Good, and must be disregarded if it ever does so.  Technically, this means Tau can be religious or non-religious, as the Greater Good is not a religion (due to lacking an afterlife and supernatural aspects, with the closest things to figures of worship being the Ethereals).  This sounds all fine and dandy, but the Ethereal class, who are responsible for maintaining The Greater Good, have been shown to be less benevolent than believed and have been using their unnaturally powerful charisma to subtly oppress the Tau and use them to further their own agendas.
**The Farsight Enclaves, who have thrown off Ethereal rule, are the exception in that they have rejected The Greater Good, seeing it as the method of oppression used to keep the T'au under complete control of the ethereals.  Due to this, if one considers the Greater Good a religion, The Enclaves are irreligious.
**As of the 4th Sphere Expansion disaster, Chaos Tau are starting to become a thing.
**At one point, the Earth Caste gathered Genestealer-infected Tau and studied them to see what would happen.  Of course, a Genestealer cult developed and naturally they violently escaped control and surveillance.   According to rumors, they've even produced a Genestealer-infected Ethereal. 

* The Eldar have varying views on religiosity depending on their type.  Their religion is polytheistic, with henotheistic offshoots, and Ausryan was the highest ranking god.  However all of the Eldar gods were murder-raped to death by Slaanesh except for Isha (taken by Nurgle), Khaine (shattered and flung into realspace), Cegorach (hiding in the Webway) and Ynnead (born long after Slaanesh's birth).  Their Pantheon's religious practices aren't fleshed out save for those of Cegorach, Isha, and Khaine, via the Harlequins and Aspect Warriors.  With most of their gods out of commission, Eldar religious worship is of a deistic bent.
** Craftworlders and Exodites almost exclusively worship the original Eldar pantheon, though some engage in henotheistic worship of only one of the gods.  Asuryan is more popular among Craftworlders while Isha is among Exodites, though nearly all give Khaine some tribute during war.
** Corsairs are all over the place, though Khaine is a popular choice given their more militant nature.  
** Being agents of the Laughing God himself, the Harlequins' worship is centered around [[Cegorach]], whilst still paying minor tribute to the other gods.
** The new faith around Ynnead, the Ynnari, is rapidly growing but have yet to establish teachings or rituals. 
** Unique among the Eldar, the Dark Eldar are irreligious for the most part and while they believe some gods exist they're too self-centered to worship them (this is canon).  They're often also anti-religious to boot; a major landmark of Commorragh is a landfill of religious icons called Iconoclast's Mound, and one Wych cult - the Pain Eternal - revolves around killing religious people and destroying shrines and holy sites.  The sole exception, except for Dark Eldar who stop being Dark Eldar, are the [[Incubi]] who hold [[Khaine]] in high regard.
** The Ynnari have encountered atleast one ancient Craftworld that turned into an entire Genestealer cult in a misguided attempt to avoid getting their souls consumed by Slaanesh as their ship had no infinity circuit present. We're not sure if this worked to any capacity (if at all, given the Hive Mind does not absorb souls), but they were taken down by the Ynnari for obvious reasons.
** There are numerous rumors of a very small number of Chaos Eldar, but these are barely fleshed out and heavily classified in-universe.  There have been verified Nurgle-worshipping Eldar and persistent rumors that some have embraced Slaanesh without becoming soul-food.  Apart from this, some Dark Eldar have been willing to summon Chaos Daemons or work with Chaos worshippers ([[Fabius Bile|or allies of Chaos]]) to further their own ends.  

* While the Necrontyr had religions before certain [[C'tan|star entities]] [[Necrons|roboticizied them]], there's little known about them.  At least one of them had gods, given the implication the C'tan co-opted the Necrontyr religion beforehand.  There was at least one case of a religion revolving around sun worship in pre-Biotransference day - which even had a sect that practiced ritual sacrifice - and one with ancestor worship.  With the change to Necrons taking the higher though processes of most of them, any Necrons who can comprehend faith and religiosity either worship the C'tan, their ancestors or have become irreligious.

* The Tyranids themselves are irreligious, being spehss bugs and all, but understand at least a few of the advantages of religion.  [[Genestealer]]s infect people and together they establish cults on targeted worlds, such as one worshipping "Children of the Stars", a perversion of the Imperial Cult (such as one that worships a [[Swarmlord|four-armed]] version of the Emperor) or something else like "Celebrants of Nihilism" (yes, that's a canon Genestealer cult name).  Psychic influence is often involved and, notably, the Genestealers do not consider themselves gods because that would require self-awareness on their part. Once the Tyranids arrive en-masse, the cult-gets assimilated along with all non-Tyranids willingly or not.  An interesting tidbit is that the Hive Mind stops the Tyranids from attacking the cultists in early stages of the invasion and leads them on, only to later override the Genestealers' wills and and make them slaughter the cultists if the cultists don't just throw themselves into the nearest digestion pool first.
