War Chief incident

The "War Chief incident" (PROSE: CIA File Extracts) was an event where the Renegade Time Lord known as the War Chief leant his assistance to the War Lord's scheme to use a War Game to create a army of humans to conquer the galaxy and create a "United Galactic Empire". The War Game consisted of thousands of human soldiers abducted from various conflicts in the history of Earth and brainwashed to continue fighting so as to determine the best soldiers for the War Lord's army.

The scheme was uncovered by the Second Doctor who worked with the resistance to bring an end to the fighting and notified the Time Lords of the event. The Time Lords saw to the return of all the abducted humans to their native times and places and subsequently tried and dematerialised the War Lord and his associates for their crimes, whilst also confining their homeworld in a forcefield. The Doctor was himself captured and tried for his interference in the universe, as he'd feared when calling in the Time Lords, and subsequently sentenced to a change of appearance and exile on Earth.

Although rumours that the Master had been implicated in the event existed on Gallifrey, Rowellanuraven believed them to be fanciful fabrications, much like the "obviously" false claim that Goth had been an associate of. (PROSE: CIA File Extracts)
