Orphans of the Future

The Orbus Postramo (Orphans of the Future) was an aliens-worshipping cult formed in the 15th century. By the 21st century, it was divided into two rival factions — the Crimson Chapter and the White Chapter.

History
After the cult's defeat, Duke Giuliano organised the survivors of the Brotherhood of Demnos into a beneficent group known as the Orbus Postramo. (AUDIO: Dreamland) His journal, the Book of Tomorrows describing his adventures with the Doctor and Sarah Jane Smith, became their holy book. 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.
