Mathara

Mother Mathara was a member of Faction Paradox. She captained the Faction's surviving warships. (PROSE: Interference - Book One and Book Two, The Ancestor Cell)

In her early days of the Faction, she took a lover who tried to prove his worth by going into her past and "hacking out" every terrible event and memory in her life. This left her without any sense of distress, as now she had technically lived her whole life without it, and when their relationship failed, the pain was too much for her to bear. She made sure the man's mother died in childbirth, erasing all but a few stubborn traces of him from her memory. From that moment on, she would destroy the past events behind any and all collected cherished memories, believing it renewed her. (PROSE: The Ancestor Cell)

When Fitz Kreiner arrived on one of the Faction's warships after having been sent through the Cold, Mathara initiated him into the Faction. (PROSE: Interference - Book One and Book Two)

One of her protégés from Earth was considered a "very promising young cousin" by Father/Mother Olympia. (PROSE: Newtons Sleep)

Later, Mathara led the Faction warfleet to the planet Dust, accidentally infecting the Third Doctor with a biodata virus during his paradoxical death. She observed the changes in the Doctor's timeline, already knowing the result of what was done would not be seen until the time of the Eighth Doctor. (PROSE: Interference - Book Two)

Nearly three centuries into the War in Heaven, the Faction had devolved into a militaristic sect of terrorists (PROSE: The Gallifrey Chronicles) This sect was led by Mathara and her warships. She allied herself with Uncle Kristeva and went back to the War's beginning, prior to the Event (PROSE: The Ancestor Cell) or the Cataclysm, (PROSE: Alien Bodies, The Book of the War) to launch a new front against the Enemy. (PROSE: The Ancestor Cell, The Gallifrey Chronicles)

Mathara's fleet invaded Romana III's Gallifrey on the eve of the Event while the planet was under the corrupting influence of the Edifice. She and her fleet were obliterated when the Eighth Doctor used the Edifice to destroy all of Kasterborous in an attempt to end the War. (PROSE: The Ancestor Cell)
