Short answer

The Prologue is a free introduction to Noa's first steps as the Collector. Panache says it begins a mystery spanning centuries and includes the choice of the companion who will accompany her; it is separate from the paid PC Early Access release.

What the published information confirms

Panache directly calls the Prologue free, connects it to Noa's beginning, and describes a mystery spanning centuries with a companion chosen to walk beside her. Those points define its purpose without needing an invented demo label.

What remains unconfirmed

The official page published for this guide does not state a completion time, a complete chapter list, save-transfer behavior, or a separate platform schedule. The Prologue page therefore explains availability and narrative position rather than promising unsupported scope.

What to do next

Download the Prologue when you want a no-cost introduction to Noa and the setting. Move to the Early Access storefront pages only when you want the larger current PC build, and review the live store notes for any differences between the two releases.

What it is useful for

Use the Prologue to judge the premise, presentation, and opening flow before paying for Early Access. Steam community posts identify the same Prologue as the playable build used during Steam Next Fest, while the official game page continues to present it as the free starting point.

What remains unknown

Neither the official game page nor the evidence collected here confirms a fixed completion time, a save-transfer guarantee, or a permanent promise that every Prologue feature matches the paid build. Those details should be checked in the current download listing rather than inferred from the word free.
