I started planning the intricate systems that define the way the library's logistics could work. How late fees are handled, the proper technique with which our librarians should "shush" noisy readers, I even made a neat classification system for books that can help us organize the shelves! In honor of the new old flooded house project that I didn't get to finish, I opted to name this system with the delectably damp name "the Dewy Decimal System."
I needed a place to document this system in text, so I went ahead and wrote over one of the books I found laying around. I hope no one minds! It didn't seem too important; it only contained some strange drawings of outlandish-looking symbols. One page even had some particularly peculiar imagery of someone licking these dastardly eldritch glyphs! It was clear this book was complete nonsense and likely wouldn't be of any use to us in the future, so I didn't think anyone would miss it.
