Overdue!

From publisher blurb: In this system-agnostic game in a fantasy world, the players are all agents of the Library, sworn to carry out its will. In this one-shot they can become entangled in book-themed royal intrigue, outwit a dragon who has taken control of all scientific journals, save the kingdom, and, most importantly, retrieve an overdue library book. This is a probably-no-combat one shot adventure, suitable for dungeon-themed games of any level or a wide variety of other systems. Content warnings: Alcohol, nothing else really as far as I can think. Assumptions about the world: Contains humans, gnomes, human-bird hybrids, libraries, books, scientific journals, dragons, a geographically improbable assortment of teas. Approximately medieval fantasy.
