An Age of Darkness
The Red Book is a major artifact of the world, possessed throughout the ages by many learned men and women, but always lost eventually. It was recently unearthed in the catacombs beneath the Great Library of Highever, and used by the librarian of the time, Dorn Greymantle.
The book measures twenty-three inches wide and eighteen inches tall. It seems to be around nine inches thick, though the contents of the book would indicate that it contains far more information than the number of available pages would be able to hold. It was supposedly written by the now-deceased God of Fate Nu sometime around the Brightmaidens arrival.
