Defeat the encounters in all five haunted books. Reading a description and putting the book back does not clear its monster. Use the book’s open action, win the encounter and check the remaining count.
Which books count?
Look for the marked books around the Arcane Library:
- The Art of Death
- The Song of Stone
- Grimoire Esoterica
- The Demesne of the Dead
- For Whom the Giant Weeps
The countdown should reach zero. If it still reports one remaining, search for the uncleared objective instead of re-reading an already completed title.
The required tome is a separate step
After the five encounters, use the restored blue teleporter to enter the Forbidden Text Wing. The magic tome required for the story has its own encounter. Obtaining it is not the same task as clearing the original five books.
Check the ladder and upper ledge before committing to the room’s final bookshelf interaction if you are collecting optional items. The library’s Tablet Shard entry remains a collection goal separate from the teleporter requirement.
Why is the gate in Fina’s psyche still sealed?
The first memory visit cannot open the entire route. Follow its scenes, inspect the gate and the eastern cliff, then return to reality. The book provides the return route to the library.
Continue to Tower of Mysidia, reach the summit and complete Sakura’s memory-sharing sequence. Enter the psyche again afterward. The added memories open the previously incomplete route; a physical key bought or found elsewhere is not the missing condition.
Prepare for the second visit
Fina is unavailable inside this sequence. Before returning, put healing and recovery on another available character instead of depending on commands that leave with her. The later visit includes battles, unlike the initial exploration-only stretch.
Follow the newly available route and the story markers back toward the gate. The main walkthrough places this sequence between Nameless Ruins and the subsequent Gronoa journey.
