Jonah (ship)

Jonah was Sabbath's steam ship, named ironically for the Biblical Jonah. (PROSE: The Adventuress of Henrietta Street) Octan built the Jonah, and fitted it with a chameleon circuit which did not function properly. (PROSE: Sometime Never...) It was some twenty yards long and about twelve yards across. It allowed Sabbath to have a degree of time travel. This was greatly improved when Sabbath used the Eighth Doctor's second black heart. (PROSE: The Adventuress of Henrietta Street)

Sabbath took the Jonah to Selonart, using it as a boat to sail the planet's seas. The ship was manned by a crew of apes. (PROSE: The Infinity Race)

Soul and Zezanne took the Jonah after Sabbath's death and piloted it to London in 1963, where it adopted the form of a police box. By then, Soul, who resembled the First Doctor, had lost his memories and believed himself to be the Doctor and Zezanne to be his granddaughter Susan, thus providing a new start for the history of the Doctor in the post-War universe, (PROSE: SometimeNever...) following the wiping of the Time Lords from history. (PROSE: The Ancestor Cell, The Adventuress of Henrietta Street) "The Doctor" began referring to his ship as the TARDIS, a name "Susan" made up from the initials. (TV: An Unearthly Child)
