THE DOCTOR AND HIS TARDIS ARE TAKEN OUT OF time and drawn into a vast space station. This is the location of an inquiry designed to investigate the Doctor’s actions, which are alleged to include transgressing the First Law of Time and conduct unbecoming a Time Lord.
The tribunal comprises the Inquisitor, the 15 most important Time Lord jurists, and the Valeyard or ‘learned Court Prosecutor’. The Valeyard uses the Matrix to screen two edited examples of the Doctor’s hazardous and erratic interference in the lives of others. The first is set on a primitive world known as Ravalox and the next is on Thoros-Beta, the planet of the Mentors.
