A deckbuilder where every card is a real book. You’re the new librarian at a small, forgotten private collection. The previous librarian left detailed notes, a locked room, and a community of collectors who expect things that aren’t in any job description.

Books are your cards. The library is your collection. Your deck fights their deck.

You build a 30-card deck from real historical texts — the Picatrix, the Voynich Manuscript, Newton’s Principia, Fibonacci’s Liber Abaci. Each book has Attack, Health, a Study Points cost, tags, a physical format, and abilities grounded in the actual content of the text. The Picatrix does not shoot fireballs. It does what the Picatrix does.

Seven classes — Researcher, Classicist, Occultist, Archivist, Cryptographer, Conservator, Detective — each with a unique hero power and class-specific cards. Seven locations — flea markets, antiquarian shops, rare book shows, estate sales, night markets, private collections — with eight opponents and a boss at each. 63 encounters total. Hearthstone-style SP mana from 1 to 10.

Five book formats function as tribal synergies: Pamphlet, Paperback, Hardback, Folio, Manuscript. Eight editions modify runs: Annotated, First Edition, Illuminated, Signed, Foxed, Counterfeit, Gilded. 600+ cards, all real books.

Between runs, you explore the Harlan Collection in first person. Browse shelves. Check the mail. Subscribe to a Rare Book Club. Bid at auctions. Buy blind lots at garage sales. Talk to visitors. Search for the previous librarian’s hidden notes.

The Ashworth Manuscript is the central mystery — a 19th-century predictive methodology in five fragments, scattered across bosses. It is not supernatural or encoded. It is worse than that: it works. Everyone wants it. Four endings determine what you do with it: keep it, publish it, sell it, or burn it.

No magic. No monsters. Just knowledge that should not be possible, and people who will do anything for it.
