Timeline

The single most common source of contradictions in long-form work.

Days of the week versus dates versus stated intervals
Season and weather against how much time has passed
Travel time between places, repeated consistently
Pregnancies, school terms, court dates, sentences — anything with a fixed clock
'Three years ago' references that shift as the story moves
Moon phase, harvest, festival or holy day if you named one
Flashback placement — does it fit before the scene it explains
Ages of children relative to elapsed time

Geography and world

Readers draw the map whether you gave them one or not.

Direction of travel and which side of the river/coast/mountain a place sits on
Layout of recurring interiors — which door, which stair, which window
Distances stated in one chapter versus implied in another
Population and scale (a village can't host a standing army)
Currency names, denominations and what things cost
Rules of the magic or tech system, and every exception you allowed
Government, titles and who outranks whom
Language and naming conventions across cultures

Objects and threads

Anything you handed a character, you must account for.

Where each significant object physically is, right now
Weapons and ammunition — carried, lost, reloaded
Letters, keys and documents: who holds them and who has read them
Wounds, bloodstains and torn clothing across consecutive scenes
Animals and vehicles left somewhere and never retrieved
Promises made by characters that the plot must eventually honour
Questions raised on the page that were never answered
Foreshadowing planted and not paid off

Voice and craft

Not strictly continuity, but the same kind of drift.

POV discipline — head-hopping inside a scene
Tense consistency, especially around flashbacks
Chapter naming and numbering conventions
Formatting of thoughts, dreams, letters and texts
Spelling of invented words, kept identical throughout
Epigraphs or interstitials — present in every part or none

Or let it run while you write

Quillvein keeps this list against your own canon and tells you the chapter and line where a contradiction started — and lets you keep it when it's the twist. Send me the checklist and an early-access seat.
