The Celestial Intervention Agency believed that the War Chief had fled from Gallifrey in a stolen Type 42 TARDIS. (PROSE: CIA File Extracts)
Some accounts suggested that the War Chief's TARDIS this TARDIS had been one of the only two that had ever been stolen, up until around the time of the Second Doctor's trial: the Master's first TARDIS. (PROSE: Doctor Who and the War Games, Doctor Who and the Doomsday Weapon) However, according to other accounts, the Master's original TARDIS was a Type 45 (PROSE: The Dark Path) or a Type 40 Model B, (GAME: The Legions of Death [+]J. Andrew Keith, The Doctor Who Role Playing Game (FASA, 1986).) and other accounts suggested that the War Chief and the Master were different individuals. (PROSE: Divided Loyalties [+]Gary Russell, BBC Past Doctor Adventures (BBC Books, 1999)., GAME: The Legions of Death [+]J. Andrew Keith, The Doctor Who Role Playing Game (FASA, 1986).) One of these accounts contradictorily referred to the War Chief's TARDIS as a Type 42 in one instance, (GAME: "Player's Handout" [+]Part of The Legions of Death, J. Andrew Keith, The Doctor Who Role Playing Game (FASA, 1986).) and as a Model 43 at greater length in another. (GAME: "TARDIS Model 43" [+]Part of The Legions of Death, J.
