Biography
Early life
The daughter of Potentate Dray lived with him and her mother in a palace in Urbania. (AUDIO: The Curse of Fenman) She once met Dorian Gray, who would later describe her as being both "revered and reviled" and said that her name could make entire empires flee. (AUDIO: Shades of Gray) She eagerly awaited the inheritance that she would get once her ill mother died.
When the people started to rebel against Dray, Avril Fenman, inhabiting the body of Carla, devised a scheme to get his daughter to Zordin should it become necessary for her to escape. She did not wish to leave and, when she realised that the First Family was going to be overthrown, she killed her father, let the rebels into the palace and planned on playing the victim and feigning ignorance of her family's crimes. (AUDIO: The Curse of Fenman)
Becoming Ruth
Avril convinced Dray's daughter that she had to leave and implanted a crystal from Deirbhile into her palm before erasing her memory. She travelled to Raster, destroying each ship that she travelled on with thermonuclear charges to cover her tracks, (AUDIO: The Curse of Fenman) and boarded a ship to Zordin as a member of staff. She briefly met Bernice Summerfield and Jack, asking them to strap in as they reached the spaceport and expressing her surprise when the spaceport suddenly disappeared. (AUDIO: The Kraken's Lament)
On Atlantis, she became Ruth, a priestess of Poseidon who remembered living there all her life. She had little memory of her parents, but remembered having a close relationship with Leonidas and Charis. When she greeted Leo and found that he did not know her, she joined him as a Historian, (AUDIO: The Temple of Questions) unaware that Avril was using her to get close to Benny through Leo and his ring. (AUDIO: The Curse of Fenman) She heard Pallis's broadcast. (AUDIO: The Temple of Questions)
Defying the Epoch
After Ruth and Leo met Benny and they decided to go to the Great Leader's underwater base, Ruth was remapped to become the sole priestess of Poseidon so that she would be able to summon the Chariot of Poseidon to get there. The Great Leader forced them to take part in a game during which she worried that she might have unknowingly been a traitor to Benny, but, following the Great Leader's destruction, Benny assured her that that was not the case. (AUDIO: The Temple of Questions)
Ruth kept Benny at a safe house on Leo's orders to keep her safe and helped her in a failed attempt to escape when the Hierophants came for her. They examined the changes to Atlantis and joined the Historians at the Senate, finding that Leo had been remapped to become a Hierophant called Traulus. Ruth and Benny then went to reboot the Great Leader due to the stability that he provided, but the Transuniversal Export building had transformed into a spire and they waited at the top of it as nothing destroyed the city. (AUDIO: Private Enemy No. 1)
The Epoch took Ruth and Benny and made them watch two other versions of themselves in different realities to work out which version of them was the real one. She began to remember moments from her life before Atlantis and was joined by the version of her from the Victorian London reality, who shut down the field around the solar system so that she, Jack and her version of Benny could escape. One Ruth was teleported to the London reality, but the other remained behind due to the device running out of battery and trapped Benny in a stasis chamber to survive the destruction of the reality they were in. (AUDIO: Judgement Day)
Travels with Benny

Ruth found herself on another planet circa 2615 and worked as a lookout for a con artist, who later gave her an identity card. She searched for Benny without success until she overheard a discussion about the worship of the Beneficiary on Lyndyaz and travelled there to study archaeology at University One, becoming Harry Burtenshaw's assistant and waiting for Benny to show up. In 2616, Benny showed up and, after she and Burtenshaw defeated Gabriella and Federico Dominicci, Ruth left with her to find Peter on Legion. (AUDIO: Brand Management)
Having rented a faulty spaceship Benny and Ruth crashed on Drahva looking for a previous ship that was there. After being captured by Zabel, Shekkina thought that Ruth was their ancient Empress. She wasn't happy when Shekkina said she needed a consort. She was the made to preside over the court and annulled marriages. She chose Gorath to be her consort. On her night before the wedding she was taken to cells. She discovered that she was to be buried in cement. (AUDIO: Empress of the Drahvins)
Learning of the Sphere of the Serenity which could lead them to Legion, Ruth and Benny disguised themselves as nuns and joined the Sisters of Celestion in order to gain access to the Talishante Monastery. Ruth suspected Mother Aurelia after Sister Caitlin and Dr Gaiter were murdered and worked with Sister Marianne to investigate, unaware that she was the real murderer. Sister Marianne attacked her and she went to Benny's aid with Bishop Synesius, after which she and Benny left with the Sphere on a medical ship. (AUDIO: Bad Habits)
Ruth and Benny were kicked off of the medical ship because of Benny's drunken antics and they continued their journey with Ray in his taxi until it was pulled down to Kaff Zarnak by Carol Bauer and Yukon 9's tractor beam. They joined Dr Bauer and Yukon, whose interspecies relationship took Ruth aback, in evading the sand roaches and making their way to Jared Jones at the top of Xanadu Tower to escape. Dr Bauer, Dr Jones and Ray were killed and Ruth and Benny left the planet with Yukon in a shuttle, dropping Yukon off before continuing towards Legion. (AUDIO: Paradise Frost)
Settling on Legion
Info from The Slender-Fingered Cats of Bubastis needs to be added
Ruth and Benny arrived at Legion City and found Peter Summerfield, Irving Braxiatel and Jack in the White Rabbit. (AUDIO: Paradise Frost) They went with Peter to decide what to do about the Vesuvius and investigated Sheira Rynn's apparent murder, in the course of which Ruth discovered that one of the cryo-pods had recently been active, helping them realise that Sheira had disguised herself as Rickard Karne. She learnt of Peter's boyfriend, Antonio Tulloch, and mentioned him to Benny. (AUDIO: Vesuvius Falling)
After Benny was contracted to recover Dorian Gray's portrait from Triptic House, Ruth and Jack joined her. The trio used a process similar to a séance to relive the memories held by the portrait, with Ruth taking on the roles of Caitlin, Sam and Victoria. Upon awakening, they met Dorian, who told Ruth that he knew her in her original life and that her name could turn back whole empires. (AUDIO: Shades of Gray)
Ruth found that Peter was very different from the Peter that Benny told her about and hoped to befriend him for Benny's sake. She approached him and tried to get to know him better, but he was dismissive and told her that Antonio believed that he should keep away from her. Jack attempted to speak to him as well and planted a video bug in his apartment which he and Ruth watched; they saw Peter talking to himself and chose not to tell Benny about it yet. (AUDIO: Everybody Loves Irving)
In a simulation from Benny's mind, when she was in Atlantis she was worried about not fitting in. This simulation then later helped Benny defeat simulations of her enemies from her memory. (AUDIO: Many Happy Returns)
Working for Irving
Info from Filthy Lucre needs to be added
After Jack plugged in a WonderBox 3000 hologram cube which he did not realise was a prison for the Great Shifting Wurm, he, Benny and Irving were embroiled in an adventure which came to an end when they had Ruth unplug it. (PROSE: Wurm Noir)
During Advent, Irving sent Ruth, Benny and Jack to deliver documents to Harrison in the Theia Quadrant on behalf of Till Madden. After they did so, they learnt of a distress call from Nemeqit which they went to investigate, finding Bel and Lud in a dome called Eden. Ruth and Benny looked into the Nemeqitian religion at their request, in the course of which Ruth was almost suffocated by quicksand, and they eventually realised that Bel and Lud were children of the planet; the two of them left Eden and became new worlds. (AUDIO: A Handful of Dust)
On Advent Day, Ruth told Peter that Antonio was imaginary and was surprised when he joined them in travelling to the Crater Base. Avril manifested through him and told Ruth the truth about who she was before Atlantis and how she had been used to get close to Benny. She was upset at what she learnt about her past life as she did not like the person that she had been, but Jack reassured her that she was a different person and had the choice not to let that life affect her present one. (AUDIO: The Curse of Fenman)
Like Jack, Ruth claimed to be busy when Irving asked for somebody to investigate Danny Crosby's show, so Benny was sent instead. (AUDIO: White Christmas)
Capture by the Epoch
Ruth and Jack went with Benny to Saravas when she was invited to take part in Big Dig and both ended up doing menial tasks for Shepton Rothwell and Ronnie Brockman despite being part of her entourage. Shepton, under the control of the Epoch, made Ruth believe that Benny was romantically interested in Jack, but she was conflicted when she confronted her about it as she simultaneously believed it to be true whilst knowing that it was not. Upon entering the Saravasian tunnels, Shepton made Ruth, Jack and Ronnie paranoid and they all ran away from Benny. (AUDIO: Big Dig)
Dr Bernard Springmoore and the Epoch removed Ruth and Jack from the timeline and remapped them to make them think that they were called Brooke and Troy, believing that removing them from Benny's life would reduce the temporal instabilities around her and also make her more vulnerable to remapping. (AUDIO: In Living Memory) After being transmatted off of the planet, Benny had no memory of either of them. (AUDIO: Big Dig)
To bury Benny's identity after capturing her, she and her friends were remapped to believe that they were actors, with Ruth becoming Ayesha Antoine. They realised what was happening and escaped to the Heart of Time with Victorian Benny, who threw herself and Dr Springmoore into the Time Vortex and reset the universe, rendering the Epoch redundant. When Benny suggested that, rather than return to Legion, they use the Epoch's technology to find those that they had lost, Ruth said she would like to find Leo. (AUDIO: In Living Memory)
Later life
Ruth entered into a relationship with Jack and accepted his marriage proposal. Whilst she wanted to remain on Legion in case Benny needed them, Jack wanted to leave their life on Legion behind and start a quiet life elsewhere. To compromise, they agreed that they would move to a planet near Legion.
A shard of the Glamour transported Ruth, Benny, Peter and Jack to the 51st century where they became trapped in a time eddy and sent postcards to the Twelfth Doctor to get him to find and save them. They appeared in 2015 Sydney and awaited the arrival of the Pyramid Eternia, which they planned to return to the 51st century by recovering the Glamour. The Doctor managed to resolve the situation and reverse what had happened, although they all retained their memories. (PROSE: Big Bang Generation)
Alternative timelines
The Epoch placed three versions of Ruth in different realities: one was with them (AUDIO: Judgement Day) and was saved from her reality by Avril Fenman, (AUDIO: The Curse of Fenman) one was on a prehistoric Earth and was erased before she could be eaten by a Tyrannosaurus rex like her Benny and one was in Victorian London. The Victorian Ruth ended the Epoch's control of the solar system (AUDIO: Judgement Day) and died leaving the Epoch's base. (PROSE: Adorable Illusion)
