The Book of the World was an enigmatic tome discovered in Asram in approximately 1254 DR; from the oxidation of the pages, the book was probably created some 400 years before that. The book consisted of some 300 sheets of a thin, flexible metal upon which a simplified runic script in an extremely ancient form of Thorass had been scribed. Only a single copy of the book was ever found, but it was evidently once the center of a body of religious beliefs. It contained a massive amount of mythological content, apparently having sprung from a sophisticated culture of a kind never known to have formed in Asram.
