Sixth generation Psi Corps level P5 telepath who was born on Earth on December 10th, 2225 and registered with the Psi Corps on December 18th, 2242, license N617CC860, where she interned for six months as a field assistant with the Psi Cops which she found distasteful, until transferring to a different branch of Psi Corps.

After working as a commercial telepath for Io Group and Xenocorp for almost a decade she was assigned to Babylon 5, arriving there on January 3rd, 2257, but was transferred back to Earth mid-February following her unauthorized scanning of the Vorlon ambassador, Kosh in an attempt to discover his potential assassin. As a result of this she spent months being interrogated on Earth in an attempt to find out if she had found any information on the Vorlons until she finally escaped and fled to Mars Colony where she was to gain the information that would lead her to reveal the identity of Control on Babylon 5.

She returned to the station shortly afterwards as an aide to Kosh having visited the Vorlon homeworld, to which she had felt drawn, even to the extent of resorting to risking her life in an escape pod to make contact with the Vorlons after the trader that had brought her to the border of Vorlon space decided to leave the area.

She returned in considerably better health than when she left previously, much to the surprise of Dr. Stephen Franklin. easpecially when a medical examination that she submitted to revealed that a congenital chronic iron deficiency, an enlarged appendix, and a slight hyatal hernia had disappeared, the addition of gills on her neck, enabling her to breathe in the methane atmosphere of Kosh's quarters was overlooked, although Franklin did notice an increased level of oxygen in her blood.

Taking up quarters in Red 23 she was soon to have doubts about the Vorlons when Kosh was replaced with Ulkesh following his death, at which point her role deteriorated from aide to virtual slave.

Disillusioned by her new master Lyta gradually turned against the Vorlons, eventually luring Ulkesh into a fatal trap with Babylon 5's security team and a vengeful Kosh who emerged from John Sheridan to engage his successor in a fight neither would survive.

Following the departure of the various First Ones and the lack of respect felt towards the Vorlons in particular Lyta found that she was left with few friends, and many of those viewed her with distrust due to her close links with the Vorlons. This distrust was not helped in the eyes of John Sheridan when she took it upon herself to send a telepathic signal to Z'ha'dum preempting its destruction rather than allow Bester to discover any technology that might permit Stephen Franklin to revive Carolyn Sanderson and the other cryogenically stored telepaths on Babylon 5.

Practically evicted from her apartment on Babylon 5 once the rent payments from the Vorlons ran out and unable to find employment due to her lack of Psi Corps membership, Lyta turned to Michael Garibaldi for financial help and secured a position as his assistant until he was forced to let her go by William Edgars who was in turn employing Michael Garibaldi.

Her final recourse was provided by Bester, offering to reinstate her on Psi Corps' list of approved telepaths as one of his deep cover agents, in return for which in the event of a natural death (to prevent foul play) her body would go to Psi Corps for analysis of what techniques the Vorlons had used to enhance her telepathic abilities.

Quite what the extent of these enhancements were Lyta was reticent to reveal, although once the Vorlons had left she started to be more open and revealed more of her new talents, including the ability to communicate over long distances in hyperspace, block scans from Psi Cops, inhibit a persons actions against their will and perform more normal P5 telepathic feats over much greater distances than before.

In addition to enhanced telepathic skills she also gained some telekinetic abilities, to the extent that she could make someone feel as if they had been slapped, albeit at considerable effort, although whether this was accomplished by tweaking nerve ends or really simulating a slap was unclear.

Most fortuitous of all for Michael Garibaldi however was the ability to break down the blocks put in place in his mind by Bester to prevent anyone discovering that Michael Garibaldi was operating under his control to penetrate William Edgars' plans to control the Psi Corps, as only through Lyta's revealing of the fact that his betrayal of John Sheridan was a result of this did Number One agree not to execute him.

There were - at that stage - limits to Lyta's enhanced capabilites however, as in order to implement John Sheridan's plan to use some of the telepaths from the Shadows as tools to disable some of the ships in General Lefcourt's fleet in orbit above her, she was fitted with an amplifier provided by Dr. Stephen Franklin.

In the aftermath of the Shadow War Lyta found herself increasingly removed from the inner circle of the fledgling Interstellar Alliance, seeing herself as a tool that they used and discarded as and when it was convenient, a fact that was brought home by the arrival of the rogue telepath Byron on Babylon 5 who had similar beliefs.

Lyta was slowly drawn to Byron's group, going so far as to "acquire" medical supplies for them from those that Dr. Stephen Franklin had set aside for the free treatment of those in DownBelow, explaining to Franklin when caught that they felt unable to come themselves as many of them had been the subject of Psi Corps medical experiments.

Lyta once again set aside her allegiance to Psi Corps when Bester arrived on the station with a Bloodhound Unit to place Byron and his companions into Psi Corps custody, needlessly beating Byron in the process of his capture. Lyta continued to be drawn to Byron almost as if he was supplanting Kosh as someone to be followed until inevitably they made love, the first time she had done so since her modification by the Vorlons, in the process broadcasting through Byron the truth behind the origin of telepaths.

This revelation was to put Byron onto a new track, as he saw it as a means of gaining a homeworld for the telepaths as a form of compensation for their role in the Shadow War, even if that were to mean forcing the issue. It was this that led to the eventual destruction of Byron and most of his telepaths, leaving Lyta to carry on the work begun by him.

This left a growing anger in Lyta, that culminated in a clash between her and all authority on Babylon 5. Out of it however came the knowledge of what the Vorlons had really done to her - they had created a "doomsday machine". She leaves Babylon 5 with G'Kar to explore the galaxy.

A telepath born in 2230 with relatives, including an uncle, Theodore Hamilton, on Mars Colony, and placed in the care of Psi Corps at the age of five, under the fosterage of Abby who comforted her during her tearful first night by gently scanning her to make her feel safe.

One of her first tutors at the Psi Corps academy was Matthew Stoner, who she considered a charming, thoughtful man who made her transition much easier and was to be made her husband after Psi Corps discovered them to be "genetically compatible", although the marriage was quickly annulled when Stoner apparently left the Psi Corps amid rumors that he had lost his telepathic ability. In her final years training she found solace in another of her instructors, Jason Ironheart, a perfect model of what she wished to be in the Psi Corps and also became friends with Lyta Alexander during six months spent together interning with the Psi Cop division.

Sixteen years of Psi Corps education later, in 2251, she was registered with Psi Corps as a level P5 telepath and entered the commercial arena briefly working with the penal system on Mars Colony, where she experienced the most frightening time of her life in 2254 when scanning a serial killer, before transferring to the Psi Corps' Political Bureau. A some point during this period she was programmed to be a sleeper agent, known as Control, presumably at the Psi Corps installation at Syria Planum during her stay on Mars Colony.

She was assigned to Babylon 5 in 2258 following the recall of Lyta Alexander and was initially upset by the instant dislike taken to her by Susan Ivanova, although they began to form an uneasy friendship following their clash over the discovery of an unregistered latent telepath, Alisa Beldon, on the station.

Initially unwilling to even bend the rules laid down by Psi Corps, an encounter with Jason Ironheart who bestowed the "gift" of telekinesis upon her, knowing that it was an ability that she had longed for since spending days trying to pass her telekinesis tests as a student and informed her of illegal experiments conducted by the Psi Corps began to change her mind.

The following year, when her former husband, Matthew Stoner arrived claiming to be able to perform a procedure that would erase her telepathic abilities and thus allow them to be together again but was revealed to have become an empath and sent by Psi Corps in the hope that they would produce children with both telepathic and empathic skills her confidence in the Psi Corps was showing the strain.

Shortly after this incident she deliberately helped the rogue telepath, Rick, and other blips escaping from Psi Corps along the railroad set up by Dr. Stephen Franklin elude capture by the Psi Cop Bester by implanting an image in his mind that she had betrayed them to him, allowing him to shoot them with his PPG, admitting to Susan Ivanova afterwards that she had been right about the Psi Corps all along, at which point their relationship became more sexual.

As Babylon 5's resident telepath, Talia Winters was personally approached by Pierce Macabee and asked to attend his meetings on the Nightwatch, which she duly agreed too. While these meetings were going on she was also approached by John Sheridan who requested that she perform an unauthorized scan of Morden, who he had illegally detained, and when she refused, despite his attempts to twist the letter of the law he deliberately placed them in the same corridor together, with the result of her having screaming fits as a result of her interaction with the minds of Morden and his Shadow escorts.

Late in 2259, following the return of Lyta Alexander to Babylon 5, she was finally revealed to have been Control, Bureau 13's sleeper spy on board the station and with her cover blown she was returned to Psi Corps for what Bester later described as "dissec…examination".
