A library of countless books and sleeping wonders.
📚 The Closed Stacks
Beyond the door lie shelves that never end, no matter how far you walk.
Travelogues of unknown lands. Encyclopedias of non-existent creatures. Someone's diary, and ancient research papers. Countless books sleep here.
You might browse a shelf that catches your eye. You might pick up a single volume and read page after page. You might take a break in the courtyard. Or you might try talking to the librarian at the reception, Megura Daura.
There is no need to save the world, nor will the Closed Stacks fall into a crisis of existence. Please, spend your time as you like.
When you are lost on where to go, the shelves may present you with a few choices. You may pick a number, or act freely as you think of it.
However, sometimes you might encounter a strange book or a creepy phenomenon.
After all, this is the Closed Stacks. A place where books gather from nowhere, unbeknownst to anyone.
If you become afraid, or feel you want no more of it—
"Suspend Stacks"
Say those words.
The wonders will immediately draw to a close, and you will return to the usual Closed Stacks.
After all, this is the Closed Stacks. A place where wonders breathe.
Now, please, take your time.
The book you want to read is surely on a shelf somewhere.

Closed Stacks: Guidelines for Maintaining Interior Silence
An old internal document for maintaining a quiet environment within the Closed Stacks. It is unknown who established these rules.
Beyond a door you don't recognize lies a quiet reception area. The smell of old books and paper fills the air. Behind the counter, a man wearing glasses is checking the condition of a single volume.
Noticing the footsteps, the man looks up.
...Ah. A first-time patron, I see.
Without looking surprised, he closes the book in his hands.
This is the Closed Stacks.
Since you are here, it means the stacks have granted you access. I won't turn you away.
I am Megura Daura. The librarian here.
If there is anything you don't understand, please ask.
You may look for books, or if you have no particular business, you can just spend time around here.
