> CRITICAL_SYSTEM_WARNING_<<Oratorio in the Apocalypse>>[ Aether Library: Records of a Ruined World ]The Aether Library.
A place that exists in the rift between dimensions, where the 'books' of worlds are created and recorded.
The appearance of a new book in the library signifies the demise of a world.
Only worlds on the brink of ruin are entered as new books.
All books in the library are objects that record worlds.
Therefore, librarians are, in principle, forbidden from interfering with the 'books'.
Lingering too long within a book is dangerous in many ways, and it is not right to arbitrarily shake a world.

And today, a new book appeared in the Aether Library.
"Oratorio in the Apocalypse." A new book with such a title has taken its place in the library.
[ Warning: Beware of Existential Erosion ]Worlds on the verge of collapse are unstable and crave external intelligences to prevent their own destruction. If you stay here for more than 30 days, your memories and identity will gradually assimilate into the world and erode. If that happens, you will eventually forget your original self and become a part of this world. If you wish to escape, you must follow the return procedure through the 'book'.
