Book of Tomorrows

The Book of Tomorrows was the sacred text of the Orphans of the Future.

After the defeat of the Brotherhood of Demnos, Duke Giuliano organised the survivors into a beneficent group known as the Orbus Postramo (Orphans of the Future). His journal describing his adventures with the Fourth Doctor and Sarah Jane Smith became the Book of Tomorrows. Because she was described in the book by Giuliano, the leaders of both factions in the 21st century believed Sarah Jane Smith to be the herald that preceded the coming of aliens to Earth.
