1666: Amsterdam Prologue Walkthrough — Library, Relics & Ritual

This route covers the woodland ceremony, library, hotel relics and cat sequence. It includes spoilers through Aaron’s meeting with Noa.

The earlier Prologue preview establishes the scene order; the detailed library solution below was checked in GameRiot’s Early Access recording. Match the named shelves and on-screen prompts in your game. These are sourced walkthroughs, not a playthrough from our own save.

The Prologue opens with Noa walking through the woods toward her ceremony. This is the introduction to Nux, the magic used to pick out points of interest and act on them.

1. Follow the woodland route and watch for the Nux tutorial prompts.
2. Use Nux on the indicated points of interest to light the torches.
3. Continue the ceremony and the familiar interaction when prompted; the story then moves to Clio’s library visit.

In the modern-day scene, Clio meets Professor Lucas with a coded manuscript sent by her father, Aaron. The objective is to discover how to read that message.

1. Finish the conversation with Lucas about the protected letter, then inspect the library registry.
2. Find Section VI: Ancient Writing Systems and Languages, on the level marked 1st Floor in the registry. Match the VI shelf label near the professor’s work area.
3. Hold Search at the shelf. Look down and use Take on the book that falls out; searching the shelf alone does not collect it.
4. Read Ancient Civilizations and return to Lucas. The conversation identifies the Heeparan, but the first attempt to use it does not work. Continue the investigation.

The donation clue points to Aaron’s Rembrandt bust. The registry places Section XIV, The Dutch Golden Age and the influence of Rembrandt, on the 2nd Floor.

1. After discussing the failed activation with Lucas, follow the Rembrandt clue to Section XIV upstairs.
2. Inspect the bust beside the bookshelf and balcony railing. Read its plaque, which names Aaron Long Smith as the donor.
3. Close the plaque and use the separate hold-to-Move interaction on the bust. A note drops onto the floor beside its pedestal.
4. Use Take on the Hidden Note and return to Lucas. Let the discussion and activation scene finish; the letter becomes readable and Aaron’s hotel flashback begins.

Aaron’s message leads into his 1999 visit to Amsterdam with Agnes. Continue through the hotel’s ground floor to their bedroom, where the relic search takes place.

1. Search the bag on the striped sofa and confirm the relic pickup.
2. Search the shelf beside the round mirror, then collect the Dry Leaves that fall onto the floor.
3. Open the chest by the large window and pick up all four candles one at a time.
4. After all three locations are complete, return to the bed and start the ritual.

The ritual changes Aaron into a cat, and the hotel is now frozen in time. TheSixthAxis describes a short traversal sequence that connects this flashback to Noa’s opening ceremony.

1. Continue through the hotel from the cat’s viewpoint.
2. Use the available jumps to move onto surfaces and over obstacles along the route.
3. Head down the otherworldly corridor. The sequence returns to 1666 and brings Aaron to Noa.
