The library book puzzle in Queen’s Domain requires you to collect several specific books and place them in the correct order to unlock the tower storage treasure. Some books are hidden in caves or behind secret walls, while others are obtained through exploration and NPC rewards.
In this guide, I’ll show you where to find the six books needed for the main library puzzle and how to arrange them. I’ll also cover additional books mentioned by players that may be relevant to library achievements and other bookcase slots.
The Great Work IV – Rubedo
You can find The Great Work IV – Rubedo on the starting island, below the Cemetery.
- Head to the cliff below the Cemetery.
- Look for a cave entrance with an egg outside it.
- Enter the cave and descend the stairs.
- At the bottom, look for an altar to the right of the throwing item in the center of the room.
- Use your air dashes from the stairs or from the pedestal where the throwing weapon was to reach the altar.
The book is waiting on the altar.
Upim’s Fairy Tales
Upim’s Fairy Tales is hidden in a difficult area on the second island, the water-covered island.
- From the second island, use three air dashes to travel from right to left toward the entrance to the book’s location.
- Continue through the dark area. The enemies are challenging, so be prepared.
- When you reach a hole, drop down and immediately air dash toward the ledges near the top.
- If you fall too far, you may need a Crystal or Stone Fragment to attempt the climb again.
- Once on the ledge, circle around until you find a food item and a skeleton.
- The book is beside the skeleton.
The Remaining Books Inside the Library
Koko’s Sapphic Adventures
This book is located inside the library. Find it among the books in the room.
The History of Dragons
You receive The History of Dragons from Woura after cataloguing enough enemies.
Dams and Weirs
Look for the bookcase beside the teleporter. Dams and Weirs is on the bottom shelf.
The Old Ones Beyond
This book is hidden behind a secret wall above the entrance to the room.
- Find the secret wall above the entrance.
- Enter the hidden area.
- Defeat the skeleton holding the book.
- The book drops when the skeleton dies.
Returning the Books
Once you have collected all six required books, return to the library and place them in this order:
- The Great Work IV – Rubedo
- The History of Dragons
- Dams and Weirs
- Upim’s Fairy Tales
- The Old Ones Beyond
- Koko’s Sapphic Adventures
Make sure you use the correct order to complete the library puzzle and access the tower storage treasure.
