From the introduction:
The Story Web sheet will guide you through the game. It is divided into five stages, and you’ll play one of the provided scenarios from each stage before reaching The Heart of the Wild and making your final choice. You'll follow a story path determined by rolling dice.
In every stage, each player frames a scene for their character to show how they deal with the events in the scenario you have ended up in. A scene can be a simple vignette (a solo narrative or description of an impactful moment), or can be a dialogue or action scene involving any or all of the other characters, as the framing player chooses.
