1666 Amsterdam Guide: Prologue Overview

The prologue is a compact introduction to the world, characters, and supernatural systems of 1666 Amsterdam. It moves between a mysterious forest, a modern library, and a hotel-room flashback connected to Clio’s family history. The sequence is designed to establish the story’s occult themes rather than test combat ability.

The opening section can be completed in approximately 30 minutes when you follow the objective markers and investigate the highlighted objects. Most progression is linear, but the library segment can briefly slow you down if you search the wrong shelves or overlook the registry.

Video Highlights:

  • Forest opening and the ritual area
  • Bateratze cat personality selection
  • Library investigation involving Professor Lucas
  • Aaron and Agnes’s relic setup
  • The first major supernatural transformation

The most efficient approach is to treat the prologue as a guided investigation. Explore only when the current objective points you toward a clue, then use the Focus mechanic to inspect symbols and objects. The story provides visual and written indicators when you are moving in the correct direction.

Navigation Tip

When the objective seems unclear, look for floating text, marked symbols, or a nearby interactive object before wandering through unrelated rooms.

Choose Your Bateratze Personality

The prologue begins in a forest-like setting where you light the braziers surrounding a tree. After the opening sequence, you choose the personality of your Bateratze. The available choices are presented as archetypes, each with a distinct mood and symbolic description.

At this stage, the choice is best treated as a role-play decision. The prologue does not demonstrate a separate combat style, movement ability, or puzzle mechanic for each cat. Pick the description that best matches the tone you want for the protagonist’s supernatural companion.

Mystical Personalities

  • The Spirit reflects secrets from beyond the ordinary world.
  • The Dreamer follows strange, shifting paths.
  • The Alchemist represents transformation and hidden knowledge.

All nine listed Bateratze personalities are valid for the prologue. Choose by theme unless later chapters establish additional differences.

Library Investigation Walkthrough

After the forest sequence, the story shifts to Clio in a library with Professor Lucas. Speak with the professor upstairs, then follow the objective toward the library registry. The investigation centers on Aaron’s unusual letter, the ancient Zendaris communication method, and an object connected to Clio’s past.

The library route is straightforward once you understand the order of interactions. Do not spend too long examining every shelf. The correct section is identified through the registry and the ancient writing systems category.

1

Speak With Professor Lucas

Take the stairs and talk to Professor Lucas. Show him Aaron’s letter and listen to the explanation about its hidden, organic-looking protective layer.

2

Find the Library Registry

Go downstairs and move toward the central desk near the fireplace. The registry is on the table in the center of the library.

3

Locate Section VI

Use the registry to identify the ancient writing systems and language shelves. The relevant shelf section is Section VI, close to Professor Lucas’s table.

4

Use Focus on the Roman Numeral

Hold L2 to concentrate, aim at the Roman numeral marking the section, and hold R2 to analyze it.

5

Investigate the Rembrandt Lead

Return to the professor and follow the clue about Aaron’s donated Rembrandt bust. Search the Rembrandt section for the note that advances the investigation.

Library ObjectiveWhere to GoRequired Interaction
Meet Professor LucasUpper library areaTalk to the professor
Check the registryCentral desk by the fireplaceInspect the registry
Find ancient writing systemsSection VIApproach the correct shelf
Analyze the markerSection VI Roman numeralHold L2, then hold R2
Follow Aaron’s clueRembrandt sectionSearch for the hidden note

The letter introduces several important lore terms, including the Zendaris tribe and the hippata, an object associated with protected communication. Clio’s pendant becomes significant because Aaron’s instructions point toward an object that can reveal what the letter conceals.

Once you find the note bearing Clio’s name, use the revealed clue to continue the scene. The progression is not based on a branching dialogue choice; it depends on examining the intended evidence in the correct order.

Common Sticking Point

If the library objective does not advance, return to the registry and confirm that you inspected Section VI. The correct shelf is near the professor’s desk, not in a random book aisle.

Aaron Flashback and Hotel Relics

The next sequence places you in control of Aaron during a flashback involving Agnes. This section has a mostly linear route, so the goal is not to discover an alternate path. Instead, follow the visible trail toward the hotel room and investigate the objects Agnes prepared.

Floating text and supernatural visual effects help confirm that you are moving in the intended direction. If the route feels empty, continue toward the elevator rather than searching for optional rooms.

Flashback StageRoute or LocationWhat to Do
Opening pathCity route toward the hotelFollow the linear path
Supernatural indicatorsAlong the routeUse floating text as guidance
Hotel entranceElevator areaContinue toward the room
Hotel roomAround the bed and nearby furnitureLocate the relics and mirrors
Ritual setupCenter of the roomConfirm the arrangement
Transformation sceneHotel room and supernatural realmContinue through the story

Agnes’s preparation includes ancient artifacts, mirrors positioned around the bed, and a bed that has been moved before Aaron’s arrival. Search the chest, shelf, bag, and surrounding furniture to locate the required relics. The sequence is meant to build unease, so the objects may appear deliberately old or unsettling.

The flashback then shifts from the hotel room into a surreal supernatural experience. Aaron’s perspective changes dramatically, and the cat spirit becomes central to the scene. Continue forward through the sequence rather than attempting to return to earlier areas.

Story Context

The hotel flashback connects Aaron, Agnes, Clio, the cat spirit, and the Zendaris mystery. Pay attention to the relics and transformation imagery because they establish the prologue’s central lore.

This part of the prologue is primarily narrative. It does not present a conventional combat encounter in the available walkthrough material, so conserve your attention for environmental clues and story triggers.

Fast Route, Mistakes, and Progress Checklist

A clean completion route follows the same order as the story’s objectives: finish the forest ritual, select a cat, investigate the library, then follow Aaron’s flashback. The prologue rewards observation more than experimentation, and most delays come from overlooking a highlighted interaction.

Use the following route when replaying the opening or helping another player reach the first major lore reveal.

1

Complete the Forest Opening

Light the braziers around the tree and allow the opening scene to transition into the Bateratze selection.

2

Select Any Bateratze

Choose one of the nine personalities. The available prologue information does not establish a gameplay difference between them.

3

Solve the Library Sequence

Talk to Professor Lucas, inspect the registry, locate Section VI, analyze its Roman numeral, and investigate the Rembrandt clue.

4

Follow the Flashback Route

Follow Aaron to the elevator and hotel room. Search the room for the relics and confirm the ritual arrangement.

5

Watch the Supernatural Reveal

Continue through the transformation and collector scenes until the prologue sequence ends.
