Story bible template for a series

Quick answer: A story bible is the one document that keeps a series consistent: premise, cast, places, the rules of the world, the season arc and the engine that repeats every episode. Write it before episode one. In SceneMixer each part has a home: the cast becomes character sheets and voices, the places become locations drawn once, and the whole thing is reused from episode to episode, so the bible and the screen agree.

A cast entry that works

MARA OKAFOR, 34, night-shift nurse. Wants to leave the city and tells no one. Tall, close-cropped hair, a green cardigan she wears every episode, a chipped front tooth. Voice: low, dry, quick to deflect. Keep each cast entry to one line of want, one line of look, one line of voice.
