You know what a book is lol.
In El-Bayir, books are typically made with pages of papyrus, parchment, and vellum. Books are traditionally bound with leathers, though sometimes other bindings may be used.
Books are usually copied by hand, though magical means are possible. Due to the rarity of magic, magical reproduction of books is a rare art and its practitioners are typically paid very well for their services.
Books are often accompanied with illustrations or illuminations.
The ancient Mannic peoples originally utilized clay tablets, which would be imprinted upon with styluses while the clay was still wet. They would then be fried, usually by a pyromancer, to become hard and durable. Over time, the Mannic peoples transitioned to utilizing early books and scrolls. During the Dark Age of Man, many peoples reverted to utilizing clay tablets and similar more "primitive" forms of writing before reinventing books.
