Urban Fantasy Series Bible, Built From Your Draft
Urban fantasy hides a supernatural world inside the ordinary one, and the masquerade is a web of rules: who knows, what is public, what each faction can do. Across a series those rules quietly drift. StoryHelm reads each book in your series and builds the bible that helps you keep the hidden world consistent.
Why urban fantasy series break
Urban fantasy runs two worlds at once: the real city your reader knows and the supernatural one layered on top of it. Every scene has to hold both true. The masquerade alone is a standing rule set, who is in on the secret, what the mundane public believes, what happens when the veil slips. Carry that across five or six books and the bookkeeping outgrows what any author can hold in their head.
The drift is rarely a single dramatic error. It is a vampire who needed an invitation in Book 1 walking through a door uninvited in Book 4. It is a cop who learns about the magical underworld in Book 2 acting, three books later, like she never did. The reader who has lived in your world since Book 1 remembers the rule you set, and the broken rule is exactly the moment the spell breaks.
What slips in an urban fantasy series
How StoryHelm holds an urban fantasy series together
StoryHelm reads each book in your series, one at a time, and builds its Canon, the record of your factions, your recurring cast, your city, and the lore of every power. Because the hidden world spans books, the Series Atlas lists every book’s Canon together. Its cross-book check, which runs only when you start one from your series’ Checks page and confirm its credit cost, compares what each book records about a returning character of the same name, such as appearance and distinguishing marks, naming both books when they disagree. When both books hold enough of that character’s dialogue, the check also flags a noticeable change in how the character speaks. Where two fully read books give the same event a different year, month, season or length, it flags that too. World Rules records the standing constraints each book states, the masquerade, the thresholds, the costs of magic, what each supernatural type can and cannot do, as explicit rules. Then, in a Full read, the Coherence Guardian checks that book against itself and flags the scene where a rule, a place, or a character’s knowledge contradicts what the same book established, so you decide which version is true. It does not compare rules, factions, or places from one book to the next, so the threshold Corwin crosses in Book 4 is still yours to catch.
You write in StoryHelm’s built-in editor, or import finished books, and StoryHelm, built from 61 specialized analysis passes powered by Claude, reads each book in your series, one at a time. It builds each book’s Canon from the prose, gathers them in the Series Atlas, holds your masquerade and supernatural rules in World Rules, and in a Full read lets the Coherence Guardian flag where a rule of the hidden world quietly broke within that book, pointed to its chapter and scene. The story stays yours: StoryHelm reads and analyzes, it never drafts or rewrites a line of your prose.
Common questions
Within one book, yes. StoryHelm records the rules and facts your text states in your Canon, and flags a later scene in that book that contradicts them, such as a character acting on a secret they were never told. It points to the scene; you decide. It does not compare who knows what from one book to the next.
Within each book. Every read records your factions, with their leaders, members, and allegiances, and the rules for each supernatural type, and the Series Atlas lists the entries from every book together. In a Full read, the Coherence Guardian can flag a scene that breaks a power rule the same book set up. It does not compare factions or rules from one book to the next, so an allegiance or a power rule that shifts between books is yours to check.
Places are recorded like any other canon: the neighborhoods, safe houses, and hidden doors each book names, with a description and where each one sits. Within a book, the Coherence Guardian in a Full read can flag a trip that takes impossible time or a character in two places at once. It does not compare places from one book to the next or check your city against the real map.
