The Other Scrolls

The Other Scrolls were a collection of Gallifreyan prophecies bound in reptile skin.

Willhuff found a copy in the Librarinth and gave it to the Infinity Doctor. He burned it because he did not want to know the future, preserving his free will. (PROSE: The Infinity Doctors)

After telling Saldaamir that the Eighth Doctor had possibly been compromised by Last Contact, Danny the Fish told his servants to destroy his entire collection except for a book bound in reptile hide. (NOTVALID: Fishy Business)

On Romana III's Gallifrey, the book was held in high security. (PROSE: The Ancestor Cell)
