Persephone

The Great Library of Stygia is even larger than you could have imagined, filled with so many books...that no longer exist as anything more than ghosts, every copy destroyed, every word lost to the living world. A sad thing to think about, but at least something of them endures past memory and time and the destruction of their pages and the libraries that they belonged to. You come here, at first, seeking more books than the few you own, reading books that died long before you were born, in between everything else you are doing.

One of the ghost librarians addresses you, when you come in, one day. "There may be a section of interest to you," she says. "The restricted section is off-limits to most that come here, but given who and what you are...permission may be granted, if only for a limited time. It will, of course, take time to secure the necessary permissions, even for one such as you, but would you be interested?"

You agree, curiosity piqued: what could possibly be in that restricted section? Quite a lot of things, of course, because the Great Library contains all the books that have passed out of memory and time - including those deliberately destroyed, containing information thought too dangerous to know or simply disruptive to the social order, but you've read more than one tome of forbidden philosophy and history, simply shelved with other books. What could possibly be hidden?

Eventually, you come back to the library, after some time away in the living world dealing with more than one powerful man who abuses his position and those around him, and that same ghost librarian is waiting for you.

"Permission has been granted for you to access the restricted section, for two weeks." she says, and takes you there, past safeguards and spells layered for thousands of years, blinding beneath your sight as you (briefly) examine it. Until at last she brings you into the restricted section: book after book after book, shelves and shelves and shelves of knowledge deemed too dangerous for the eyes of even the few ghosts that come to the Great Library.

And so, you read, book after lost book, about the First Age of the world. The true First Age, not the legends of the Age of the Anathema that you had grown up learning, even though your home had not held to the Immaculate faith. Sometimes you rest, occasionally you eat, but your attention is caught mostly by what's on the pages. Everything you never knew. Everything you never even hoped to know. The more you read, the more questions you have to ask, and by the time your time is up, you have read only a fraction of the books in the room and have more questions than answers, even after all that time.


Notes:
white-haired Persephone again
Despite Persephone's translucently-pale skin, white hair, and beautiful, fanservice-y white kimono (that he's wearing right over left, aka "in the fashion of the dead"), he's still the most vibrant thing in there. Like there is a noticeable difference between him and the ghosts.
there are SO MANY BOOKS. Spilling off ghost bookcases, stacked haphazardly. like, this is basically the Ghost Library of Alexandria.
