Route Tip

Treat the prologue as an interactive narrative chapter rather than a combat tutorial. Slow exploration and careful object inspection are more useful than searching for hidden fights or loot.

Exploration

Move through the forest and library at a measured pace. Environmental landmarks, shelves, stairs, and floating text help identify the intended route.

Investigation

Clio’s section centers on Aaron’s letter, Professor Lucas’s research, and a concealed message that requires a special object.

Story Reveal

Aaron’s flashback explains the connection between Agnes, the relics, the cat transformation, and Noa’s supernatural gathering.

Forest Ritual and Bateratze Cat Choice

The opening forest sequence introduces the prologue’s mystical tone. Your first practical objective is to locate the ritual area and light the braziers positioned around the tree. The scene is deliberately quiet, so look for the fire bowls and use the tree as your central landmark.

Once the ritual interaction is complete, the game presents several cats. These creatures are described as Bateratze in the available walkthrough material, while the story dialogue uses related terminology during the supernatural encounter. The prologue does not demonstrate different gameplay outcomes for the choices, so selection is primarily a role-playing decision.

CatThemeSuggested Player Preference
The SpiritSecrets, the void, and the netherworldChoose for a mysterious tone
The HermitReflection, knowledge, and eternal truthsChoose for a scholarly tone
The DreamerOtherworldly currents and uncertaintyChoose for a surreal tone
The WildlingRain, wind, soil, and natureChoose for a wilderness tone
The GuardianDuty, strength, and resistanceChoose for a protective tone
The AlchemistElements, change, and wisdomChoose for a mystical scholar tone
The ChildInnocence, curiosity, and discoveryChoose for an exploratory tone
The PageTravel, learning, and personal growthChoose for an adventurous tone
The KnightCourage, virtue, and justiceChoose for a heroic tone
Choice Guidance

There is no demonstrated gameplay difference among the nine cats in this prologue. Pick the design or theme that best fits your preferred interpretation of the story.

After the cat selection, a cutscene moves the timeline into a modern library setting. The player character becomes Clio, Aaron Long-Smith’s daughter. Professor Lucas recognizes her family connection and begins examining the letter Aaron left behind.

The transition is important because the prologue changes from ritual exploration to a guided investigation. Avoid wandering randomly once the library scene begins. The staircase, fireplace, professor’s desk, and numbered shelf sections form the main route.

Library Investigation: Professor Lucas and Section VI

Clio begins the library sequence by meeting Professor Lucas. Start by taking the stairs up and speaking with him. The conversation establishes Aaron’s relationship with the professor and introduces the unusual writing concealed inside the letter.

After the first conversation, go downstairs and walk to the desk near the fireplace. Speak with Professor Lucas again to continue the investigation. He points Clio toward the library registry and the material connected to ancient writing systems.

Find the shelfClosest section to Lucas’s tableSearch Section VILocate ancient writing material
Focus on the markerSection VI shelfHold L2 to concentrateHighlight the Roman numeral
Analyze the markerSame shelf areaAim at the numeral and hold R2Continue the letter investigation

The correct shelf section is Section VI, located to the left of Professor Lucas’s table. It contains works on ancient writing systems and languages. If the investigation appears stalled, reposition Clio near the shelf and use the concentration function to identify the Roman numeral.

The letter refers to protected communication associated with the ancient Zendaris tribe. Professor Lucas explains that the writing cannot be deciphered through ordinary reading alone. The investigation then shifts toward the pendant or key-like object Aaron gave Clio during her childhood.

Library Warning

Do not spend too long searching every shelf. The intended progression uses Section VI, concentration, and analysis. The Roman numeral is the visual clue that confirms you are examining the correct area.

The special object becomes relevant when Clio aims it at the letter. The interaction reveals Aaron’s hidden message and starts the flashback concerning Agnes. This is the main puzzle gate in the library, so listen to the dialogue before moving away from the desk or letter.

1

Talk to Professor Lucas Upstairs

Take the stairs to the upper library area and speak with Professor Lucas. The conversation introduces Aaron’s letter, the concealed writing, and the professor’s connection to Clio’s father.

2

Return to the Fireplace Desk

Go downstairs and walk to the desk beside the fireplace. Speak with Lucas again to receive the clue pointing toward the library registry and ancient writing materials.

3

Search Section VI

Move to the shelf section on the left, closest to Lucas’s table. Section VI contains books related to ancient writing systems and languages.

4

Concentrate and Analyze

Hold L2 to concentrate, aim at the Roman numeral, and hold R2 to analyze it. This confirms the correct shelf interaction.

5

Use the Special Object

Aim the pendant-like object at Aaron’s letter. The hidden message appears and leads directly into the next narrative sequence.

Aaron Flashback and Hotel-Room Route

The flashback follows Aaron as he travels with Agnes toward their hotel room in Amsterdam. This portion is linear, making navigation simpler than the library investigation. Follow the path toward the elevator and watch for floating text. These visual markers indicate that you are moving in the intended direction.

The hotel room contains Agnes’s ancient relics and a carefully prepared arrangement. The room’s objects are not presented as a conventional inventory puzzle. Instead, the scene builds atmosphere and explains the ritual conditions that precede Aaron’s transformation.

Flashback SegmentRoute or InteractionProgress Advice
Walk with AgnesFollow the clearly guided pathStay on the main route
Floating textUse the text as a direction markerContinue when the path feels uncertain
Hotel entranceFollow the route to the elevatorThe sequence remains linear
Hotel roomSearch for Agnes’s belongingsCheck the chest, shelf, and bag
Bed arrangementObserve the mirrors around the bedThe room has been prepared for the ritual
TransformationContinue through the visionFollow the supernatural calls and dialogue

Agnes asks Aaron to arrange her relics according to her instructions. Search the chest, shelf, and her bag to locate the objects. The mirrors around the bed and the repositioned bed are important visual details, but the sequence is primarily story-driven rather than a difficult placement challenge.

After the setup, Aaron experiences an altered state. He wakes as a cat, with heightened senses and a distorted view of the room. The game then moves between the hotel and a forest-like supernatural space. Follow the calls guiding him forward instead of attempting to return through the earlier route.

Flashback Navigation

The floating text is the safest route indicator during Aaron’s memory. When the environment becomes surreal, follow the calls and continue forward rather than searching for an alternate objective.

Aaron eventually encounters a woman named Noa, who identifies herself as the Collector. She calls Aaron a Batarazzi and introduces the Zantetsus. This encounter closes the prologue’s opening movement and establishes that Aaron’s transformation is connected to a larger supernatural ceremony.

Prologue Checklist and Common Mistakes

The prologue is short, but several moments can create confusion because the game changes locations, characters, and rules quickly. Use the checklist below to confirm that each major milestone is complete.

Prologue Progress Checklist:

  • Light the braziers around the forest tree
  • Choose one of the nine Bateratze cats
  • Speak with Professor Lucas upstairs and downstairs
  • Find Section VI and analyze the Roman numeral
  • Aim the special object at Aaron’s letter
  • Follow the flashback route to the hotel elevator
  • Search for Agnes’s relics in the hotel room
  • Continue through the cat transformation and meet Noa
ProblemLikely CauseRecommended Fix
The forest sequence does not advanceA brazier remains unlitRecheck the area around the central tree
The cat choice feels unclearThe game gives limited mechanical explanationSelect based on theme; no shown gameplay difference
The library search stallsThe wrong shelf is being examinedGo to Section VI near Lucas’s table
The Roman numeral is difficult to detectConcentration has not been activatedHold L2, aim at the marker, then hold R2
The flashback route seems confusingThe environment becomes surrealFollow floating text and the guiding calls
The relic sequence feels incompleteItems have not been checkedSearch the chest, shelf, and Agnes’s bag

The most common mistake is treating the library as a free-form scavenger hunt. It is more structured than it first appears. Professor Lucas’s desk, the fireplace, Section VI, and the Roman numeral provide a compact chain of clues.

Another mistake is assuming that the cat choice immediately creates a different build or route. The available prologue material does not show a gameplay distinction between the cats. Choose freely and focus on the story transition that follows.

For additional visual context, consult the 1666 Amsterdam prologue walkthrough for the forest, library, cat selection, and flashback route.

Editor’s Tip

If you become stuck, return to the last major landmark: the tree in the forest, Lucas’s desk in the library, or the hotel-room setup in the flashback. Each section has one dominant objective.
