The Time Lords are an immensely civilised, and immensely powerful, race. Yet we know very little about them, save that they can live forever (barring accidents) and possess the secrets of space and time travel. Their history has been shrouded in myth and mystery. Until now. A Brief History of Time Lords unlocks the secrets of this ancient, legendary alien race - a civilisation that inflicted some of its most notorious renegades and criminals on the universe, but was also the benevolent power that rid the cosmos of its most fearsome enemies. Drawn from the ancient records of Gallifrey, and handed down from generation to generation, this remarkable book reveals the Time Lords in all of their guises: pioneers and power-mad conspirators, time-travellers and tyrants, creators and destroyers. Be careful who you share it with.
