This book contains the Celestial language's vocabulary, pronunciation, phrasing and grammar exercises, and its words are charged with magic.

If you spend 48 hours over a period of 6 days or fewer studying the book's contents and practicing its guidelines, you permanently learn to speak, read and write the Celestial language.

The manual then loses its magic, but regains it in one year.
