Books get slotted into bookcases, and different slots want different books. The rule that makes it solvable is on the cover of each of the four god-named books: the symbol tells you which slot it belongs in.
Which symbol means which god
| Symbol on the cover | God | The book |
|---|---|---|
| Circles | Sipeha | Sipeha's book |
| 8-pointed star | Puwema | Puwema's book |
| Cross | Wodaso | Wodaso's Embrace |
| 3 Diamonds | Jigeki | Jigeki's book |
The symbols are learnable from the lore in the game, so the mapping is not arbitrary — once you have seen the four marks on the walls, the books identify themselves. Three of the four books sit behind secret doors, so how to look for them is in the secrets guide.
One practical warning: books that are merely sitting on shelves look identical to scenery, so sweep the shelves rather than trusting the crosshair.
Where the four books are
- Wodaso's Embrace is brown and lies to the right of the gate as you enter the room where you get the lance weapon. It is also the reward for the deliver-six-books puzzle in the Tower of Knowledge.
- Sipeha's book is deep under the Tower of Knowledge. Reach the Archivist Inha mini-boss — he sits behind a secret door on a ledge above the trap door that drops you into the basement. From Inha you drop down to a room with a stone statue, take the sloping corridor into a themed area, and open the secret door beside the skeleton holding a Radiant Fruit.
- Puwema's book is in the small tree area reached from the Chef Gagi spiral staircase in the Deimpo Mausoleum or from the Tower of Sin. Hug the left wall and it is on a pedestal near an Occultist Josami Warden. The ledge route works too: from the ledge overlooking the grassy cavern, airdash to the ledge directly opposite and take the book off the small stone pedestal.
- Jigeki's book is in the hidden room near the throwing needles in the Obmuer Temple, by the flame candle lizards.
Sipeha's book is the one that drags you through the whole Tower of Knowledge, so the route down there is in the Tower of Knowledge guide.
Queen's Domain book puzzle: the six books in the Tower of Knowledge
The six-slot room is in the room where the dying guard gives you the golden key, and a note in that room tells you which books it wants. The six are:
- Great Work IV – Rubedo
- History of Dragons
- Dams and Weirs
- Upims Fairy Tales
- The Old Ones Beyond
- Kokos Sapphic Adventures
Deliver all six and you get Wodaso's Embrace back as the reward, which is how the room and the god book are tied together.
The same room is where Budaen is hiding — the knight whose key opens the large golden doors near the Storm Gem. He is behind the cage, by the candles next to the wall of flesh and the bookshelves. Both of those are covered in the Storm Gem guide.
The three slots at the top of the tower
At the very top of the tower there are three extra slots, and they are not picky:
- Two near the two golden doors.
- One at the end of the top floor near the statue with the gem.
Any book will do in those, and you can pull it back out afterwards, so there is no cost to using a book you need elsewhere.
The Record of Sin has its own altar where you place books, and it uses the same system. That altar is the last thing before the final fight, which is in the endings guide.
