Library of Ruina

"May you find your book in this place." Roland, a simple fixer from a place known only as a town, finds himself one day in the foyer of the library, a mysterious place filled with books on every subject imaginable. He soon meets the head librarian, Angela, who spares him after a brief scuffle and hires him as her guide to the outside world. However, Angela has a strange method: she sends out business cards, which she calls invitations, to invite people to the library and gives them the choice of accepting or declining. If the guests accept, they must survive a deadly battle against the librarians guarding the building; if they win, they can take any book they want. If they lose, they become a book themselves. All of this serves Angela's goal - to get the one "perfect" book that can turn her into a human.
