Time Lord ghost

Time Lords had the ability to manifest as ghosts following their final death. While many accounts depicted this as a technological feat related to the Matrix, (PROSE: The Legacy of Gallifrey, Lungbarrow, AUDIO: Zagreus, et al.) others indicated this was a result of the dead still being capable of telepathy. (PROSE: The Five Doctors, Blood Harvest, Lungbarrow) Time Lord ghosts often had great powers, such as being able to control TARDISes. (PROSE: The Eight Doctors, The Chronicles of Doctor Who?)

As Rassilon's body lay "sleeping" in the Tomb of Rassilon, he was able to use his mental powers to project a spectre which spoke with a booming voice. (PROSE: The Five Doctors, Blood Harvest, The Eight Doctors) Other sources depicted Rassilon's consciousness as existing in the Matrix, (TV: The Invasion of Time, COMIC: The Tides of Time) and further sources equated Rassilon's ghost as therefore being a projection from the Matrix. (PROSE: The Legacy of Gallifrey, Lungbarrow, AUDIO: Zagreus) On one occasion, Rassilon's spirit was projected to the Doctor's TARDIS and was able to guide it through time and space to help the Eighth Doctor while also subtly changing the timelines. (PROSE: The Eight Doctors)

Multiple accounts indicated that Borusa, following his turn to villainy, was redeemed and left his imprisonment to join Rassilon's repose. (PROSE: Blood Harvest, The Eight Doctors) Another account, after Barusa's redemption, showed that after Barusa's final death, his spirit departed his body, but was somehow inexplicably merged with the crystals of the Doctor's TARDIS, allowing him to pilot it. (PROSE: The Chronicles of Doctor Who?)

In multiple versions of history, Quences outlived his own death as a ghost by preserving his consciousness in Badger's circuitry. (PROSE: Lungbarrow, AUDIO: Auld Mortality)
