Romana III

The third incarnation of Romanadvoratrelundar was, like Romana II, also President of Gallifrey. However, there are at least two conflicting accounts of other details regarding this incarnation of Romana. (PROSE: The Shadows of Avalon, AUDIO: Intervention Earth)

While Romana II was meant to regenerate into one of these versions of Romana III, this regeneration was prevented by Braxiatel sent by her into the past, causing a paradox. (AUDIO: Enemy Lines)

Gallifrey's darkest hour
According to one account, during her tenure as President Gallifrey faced its "darkest hour", and she began to clear sections of Gallifrey in order to make room to build Battle TARDISes. She personally attended the decommissioning of Quadrigger Stoyn's workstation. (AUDIO: Luna Romana)

A Matrix projection of Romana III, which called herself "Trey" aided her second self after she had returned from the Axis. She offered her Capitol to her previous self, saving her thousands of years in rebuilding the planet. (AUDIO: Renaissance)

During the final term of office, she had to deal with an anomaly in near Earth, created using the Hand of Omega. A secret society, known as the Adherents of Ohm, were trying to gain power on Gallifrey, and she suspected that Narvin might be part of it. There was an attempt to assassinate her though Tauras managed to save her. She travelled through a black hole after Narvin tracked Ace there and found out that Tauras had set Omega free from the anti-matter universe. She tried to travel back into her own universe again but was stuck in the black hole as the type 160 TARDIS she was using ran out of power. She accepted that she along with Narvin and Ace wouldn't see Gallifrey again, until Irving Braxiatel saved her and went after Omega. (AUDIO: Intervention Earth)

The return of Omega caused a war that devastated Gallifrey. Because of that, Romana sent Braxiatel to the past, in order to prevent her previous incarnation from regenerating and to avert this crisis before it happened. (AUDIO: Enemy Lines)

After the timeline was changed, Romana II was not certain whether she would eventually regenerate into the same third incarnation or not. (AUDIO: Enemy Lines)

War Queen of the Nine Gallifreys
According to a different account, Romana had, by this time, become War Queen and President of the Nine Gallifreys. She regenerated knowing she would need a harder personality for the upcoming War with the Enemy. As a result, she became less friendly towards the Eighth Doctor.

She dispatched Cavis and Gandar to Avalon, and eventually turned up herself to take possession of Compassion after Compassion transformed into a TARDIS, believing she could give them a tactical advantage in the war. Instead, the Eighth Doctor and Fitz fled inside Compassion. (PROSE: The Shadows of Avalon)

After a hundred and fifty years in power, she was approaching her first reaffirmation ceremony when she was challenged by former President Greyjan, an event which turned out to be part of a scheme by Faction Paradox to take over Gallifrey and re-write its history. The Eighth Doctor destroyed the planet to prevent this. (PROSE: The Ancestor Cell) Marnal later showed the amnesiac Eighth Doctor these events, where Romana and one of her soldiers, Mali tried to restore Gallifrey from one of the Nine Gallifreys. They discovered that Faction Paradox had wiped the Nine Gallifreys from history. Romana wept, knowing that her planet was doomed. Soon after, Faction Paradox skulltroopers closed in on Romana and Mali, and fired two shots. Before she died, however, Romana sent K-9 into the Doctor's TARDIS to prevent him from destroying Gallifrey. (PROSE: The Gallifrey Chronicles)

Appearance
According to one account, the War Queen Romana was petite, with black hair and a snub nose. (PROSE: The Gallifrey Chronicles) She had a fringe, green eyes, and a tattoo of the Prydonian Seal on her left ankle. She wore pearls. (PROSE: The Shadows of Avalon) Cuthbert Simpson regarded Romana as "beautiful". (PROSE: The Banquo Legacy) The Doctor noted that this incarnation of Romana looked like his mother. (PROSE: The Ancestor Cell)

Behind the scenes

 * Writers involved in the War arc book of Eighth Doctor Adventures novels based Romana III's described appearance on that of the American silent film actress, although upon meeting this incarnation for the first time the Eighth Doctor noted that she now looked worryingly like his mother.
 * James Goss, creator of the "Trey" incarnation of Romana played by Juliet Landau in Big Finish audio stories, asserts that the Romana III of the novels is not the same as Trey. Goss refers to Romana III as one among "other future Romanadvoratrelundars". (Vortex #56)  However, Scott Handcock and Gary Russell have stated that Trey is the third incarnation of Romana, and was always intended to be, leaving the situation of which post-Ward Romana is the third unclear.
