The Doctor is pulled out of his time stream and summoned to a Time Lord space station above Gallifrey. On his arrival it is announced by the Inquisitor that the Doctor will stand trial. Accused of conduct unbecoming a Time Lord, the Doctor refutes the allegations made against him and chooses to mount his own defense rather than entrust his fate to a fellow Time Lord. Opposing the Doctor and appearing for the prosecution is the Valeyard, an enigmatic figure who is clearly out for the Doctor. Suffering from short term memory loss as a result being taken out of time, and puzzled as to the absence of his companion Peri, the Doctor can only sit back and watch as the Valeyard mounts his case against the eccentric time traveler. The first piece of evidence is taken from the Matrix, the repository of all Time Lord knowledge. It chronicles the Doctor's interference in affairs of the planet Ravalox, a planet very similar to Earth and which was partly decimated by a fireball several centuries ... Written by
