Start with the moment, not a blank prompt
The useful first question is not how much background you can write. It is what has already happened in the opening scene. An existing plot gives an interactive voice story a setting, an immediate situation, and a reason for a character to speak. The product is an AI voice cosplay and roleplay experience built around acting inside a story. That story-led format lets you arrive at a scene with something to notice or answer, rather than facing an empty box and trying to build every piece of context alone.
