Map a Religion From Its Origin Trauma

Religions don't appear fully formed; they grow out of a shock or a revelation. Give it the origin event and the culture that preceded it, and it builds the faith outward: theology, ritual, hierarchy, taboos, all traceable back to that founding moment. Good for worldbuilders who want a believable religion with roots, not a costume.

Help me build a detailed fictional religion from its founding moment outward.

The origin event, the trauma or revelation that caused this religion to emerge, is: {ORIGIN_EVENT}.

The society that produced it had the following values and fears before the religion formed: {PRE_EXISTING_CULTURE}.

Now construct the religion across these dimensions:
- Core theology: what does this religion say about the nature of existence, suffering, and salvation?
- Sacred text or oral tradition: is the origin event recorded, and how has the story been distorted over time?
- Clergy and power: who interprets doctrine, and what do they gain from their role?
- Schisms: what is the main theological dispute that split the religion into at least two factions?
- Relationship to the state: does this religion prop up political authority, resist it, or operate in uneasy coexistence?
- A single heresy that contains an inconvenient truth the mainstream church suppresses.

Make the religion feel lived-in, not invented.
