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 the Prologue includes today
The download page presents the Prologue as Noa's opening chapter, but it does not list a fixed completion time, a complete chapter count, or save-transfer behavior. Treat it as a free introduction and check the current listing before planning a longer run.
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.
Playtime and save-transfer checks
The current download information gives no fixed completion time or save-transfer guarantee, and Prologue features can differ from the paid build. Check the live listing and in-game save options rather than assuming that free progress carries forward.
