that frightens you most.

Each character runs on their own Claude persona, anchored to their chapter in the first novel. They begin where the book begins for them. You begin wherever you are willing to.

Public demo

This build is a fixed demo. Every reply was written ahead of time, so each character offers two branching options per beat — 32 paths through a six-beat scene, ending in one of four outcomes. You cannot type your own lines here. The full version answers freely, runs the whole Book I timeline, and remembers what you told the other characters. Contact me for access.
