How to create fictional religions

Nothing moves a made world like its gods. A religion touches law, war, marriage, food and death, and each of those touches plot. Wikipedia keeps the definition plain: a fictional religion "refers to a fictional belief system" created for literature, film or games, and such systems can "be complex and inspired by or build on existing religions". This guide treats belief systems as engines of conflict and character, one room under the cluster's front door, how to build a fantasy world.

What religions do in a story

Invented faiths are old and varied. Wikipedia names Bokononism, from Vonnegut's Cat's Cradle, as "often cited as a classic in the genre's satirical criticism of religion", and calls George R.R. Martin's religions in A Song of Ice and Fire "an example of complex world building".

Game designer M. A. R. Barker argued a fictional religion must be crafted with an "anthropologist's level of realism". Chris Winkle's Mythcreants guide lists the components: beliefs carry "Explanations for existence", "Powerful beings", "Ethical standards" and "Rituals", and "Belief systems arise from the circumstances people find themselves in". A fishing people and a steppe-riding people do not worship the same way.

Decide what the divine actually is

Fantasy's structural advantage over writing about real religion is that you know the truth. Winkle again: "The best part about creating a belief system in a speculative fiction setting is that you can choose the accuracy of the belief." His dial has four settings: "Literally true", "Metaphorically true", "Partly true", or "Completely false". Andrew Wall's Craft Better Books guide starts from the worshipper's side: choose the object of worship first, "a single goddess, several gods, ancestors, natural spirits, or a literal object", and keep separate what is actually real from what believers think is real.

Everything downstream depends on that dial. Oren Ashkenazi's Mythcreants analysis of settings where the divine is provable starts from the fact that "there's no question about gods or what happens when a person dies": worship stops being faith and becomes "an act of political allegiance", and resurrection, where it exists, is rationed so that "only the rich and powerful can routinely afford resurrections". Choose that world on purpose.

Cosmology, the afterlife and the moral code

The belief system itself answers three questions. Where the world came from (cosmology). What death is (the afterlife). What is required of the living (the moral code). On the afterlife, Ashkenazi's piece is the useful one: with a proven afterlife, dying becomes "akin to making a permanent move", which quietly rewrites grief, risk, murder and war. On the moral code, Winkle notes that belief systems commonly exist to "Justify existing social systems" or to "Encourage health and survival": a code that explains why the powerful deserve power is a different instrument from one that fences the sick.

Worship, ritual and daily life

The Quill & Steel guide is blunt about the surface most writers stop at: faiths "run on three things: A story, a set of values, and rituals people do", and "'They perform sacred ceremonies' is not a ritual". Its counterexample is the detail that works: "They fast for three days before the winter solstice and burn the names of their dead". Wall's definition: ritual is "belief made visible in symbolic setting and action". Religion then leaks into everything, greetings ("May the Weaver guide your threads") and "Laws, traditions, holidays, politics, rituals, architecture, food, fashion, language". For a serial writer, one liturgical greeting costs a line and pays out for three hundred chapters.

Clergy, schisms and holy wars

Organized religions develop "Hierarchy" and "Specialization", Winkle writes, spinning off priests, monks, healers and seers; decentralized ones develop "Variation" instead. A church is a faction: it needs an age, an address and alliances like any other player in your faction web. Winkle's sharpest observation: "Once split, two factions of the same belief system are more likely to be in conflict than belief systems that are completely different." Schisms, not foreign gods, are a holy war's natural fuel. Quill & Steel agrees in capital letters: religion "stirs up conflict like nothing else", and when you add sects, rival faiths and corrupt clergy, "Do NOT skip this part".

One warning: Wikipedia's history of the trope notes that fantasy has often shown personal faith warmly while depicting organized religion "as corrupt", and Orson Scott Card criticized the genre for treating religion as "ridiculous and false". A church that is genuine, powerful and specifically wrong is the better story.

Belief and character: the devout and the skeptic

Religion reaches plot through people, and a cast should disagree about it. The devout believer, the routine believer, the skeptic and the heretic are four cameras on the same doctrine. Wall's rule of thumb: believers mirror what they worship, and worshippers of an ambivalent god "will be aloof from it as well". A faith arc, in character arc terms, is an arc where the belief itself changes: tested, kept, revised or lost.

Connect religion to your magic system

If magic exists, religion will have an opinion about it. Quill & Steel makes this its final step: "Tie it to your magic system", because "in a world where magic is real, religion will NOT stay neutral". Sanderson's Third Law essay supplies the wider principle: "how well they are ingrained into the society, culture, ecology, economics, and everyday lives of the people in the stories", and even a small power "could spawn religions, influence social mores, provoke wars". If clergy work miracles, those miracles need costs and limits, and once a god answers prayer with fire on the page, that answer is a rule every later chapter renews (Magic A is Magic A).

Drawing on real-world religions respectfully

Wikipedia is direct that invented faiths "build on existing religions", and the craft consensus is direct about how. Mythcreants on the common case: "Christianity as a whole is not at risk for cultural appropriation", being "by far the world's most powerful and privileged religion", but "there are certain specific elements of Christianity which are not so open": "Latin American Christianity, for example, has a number of unique practices which are often exotified and misrepresented by white writers". Islam "is absolutely a marginalized faith in Western countries", so "I'd avoid creating a fantasy setting where the three faiths are mixed and matched like they're interchangeable". The positive program: study widely, borrow structures rather than costumes, and portray any living tradition as its adherents would recognize it, or transform it past recognition.

Religion at web-serial scale

A serial cannot deliver a religion in one lecture (how to write exposition covers the general case). Doctrine arrives through ceremony and character: a funeral, an oath, a saint's day feast where two rivals share a table. Each ceremony shows one doctrine, one institution and one character's relation to both: worldbuilding inside a scene that also moves plot. And doctrine is canon: once the text establishes that the dead are burned with their names, every later death scene renews the promise, so write the tenets down as world rules in your story bible. The layer this builds is mythopoeia, Tolkien's word for the making of myths.

How Kanonara approaches this

Faiths and their institutions are story entities with their own records and history, doctrine is kept as world rules with chapter evidence, and chapter analysis proposes new records rather than inventing canon: the author decides what enters the world.
