Upon requesting medical treatment for their sick child, her parents, little of which is known about, were forced to give Wilat to a squad of Cardassian soldiers who claimed that they would take her to receive treatment for the virus. In reality, she was to be taken to a converted slave-labor camp that was being used by Cardassian exobiology expert Doctor Crell Moset to perform experiments on unwilling sick Bajorans in an effort to find the cure.

While Moset's earlier experiments had resulted in the painful death of hundreds of unwilling Bajorans, Wilat was fortunate enough to have contracted the virus only days after a prototype cure had been formulated, and was injected with it shortly after arrival. Unfortunately, before this perfected cure was released into the general population, thousands of Bajorans had already died from the virus.

Wilat made a quick recovery and, being the youngest 'patient' to have received the cure at the converted labor-camp, inadvertently drew the attention of Doctor Moset. Considering himself to be a sociologist of sorts, Moset decided to seize the opportunity and conduct an experiment to see how a Bajoran child would develop into maturity if raised under the harsh Cardassian education system.

During a routine raid for medical supplies in the hospital that Wilat had been born in, Cardassian troops spitefully injured several Bajoran doctors and destroyed the hospitals entire records database, which included Wilat's birth record. Shortly afterwards, her parents were summarily executed for being 'enemies of the state' - supposedly for plotting to disrupt laborer activity through a series of strikes in the town they worked in. This eliminated Wilat's last ties to her Bajoran heritage.

Giving her the Cardassian name 'Wilat' (meaning 'always watched '), Moset took her into his personal care and while he spent her toddler years experimenting viciously on unwilling Bajorans, Wilat lived in his private apartment under the care of a Cardassian attendant.

Time progressed and she spoke her first word (the Cardassian word for 'daddy') and by the time she was able to comprehend the concept of adoption, Moset had her believing that he was her legally adopted-father who had taken her into his care upon the accidental death of her biological parents. By this time he had actually grown fond of her and began to think of her as an adopted-daughter of sorts and not just a sociology experiment.

After her fifth birthday in 2362, Wilat began full-time tutoring with a Cardassian teacher whom Moset had bought to Bajor from Cardassia Prime. By now, Wilat was happily speaking Cardassian and considered Crell to be her father. She had no idea of what was happening outside of their private apartment just kilometers away from several slave-labor camps, nor did she have any reason to believe that her father was torturing sick Bajorans to 'better medical knowledge' on a daily basis.

Not being allowed to leave the apartment, nor having any other children to interact with, Wilat spend the greater majority of her free time reading what carefully-filtered material her father would import from Cardassia Prime. As a result, she is extremely knowledgeable about it's history, culture, customs and what little religious denominations exist. Unfortunately, her lack of contact with other children left her with a social awkwardness when dealing with unfamiliar people which took her years to overcome.

In 2368 an assassination attempt was made on Moset's life by the underground resistance cell 'Ornathia' when they attempted to raid his lab for medical supplies. Fortunately for him, he escaped with a third-degree phaser burn to his left shoulder but spent a week in his apartment recuperating. During this time, Wilat questioned why exactly someone would want to hurt him. Moset's response was that the Ornathia were terrorists who wanted to stop him from helping sick Bajorans. Wilat accepted this explanation (not having any reason not to) and was unaware that Moset had ordered 30 prisoners to be executed as punishment for the attempt made on his life.

When the occupation ended in 2369, Moset was already off Bajor - attending a seminar on exobiology on Cardassia Prime. By the time the Cardassian public was made aware of the loss, it was too late for him to have Wilat extracted from Bajor since all Cardassian starships were already on a course back for the homeworld. Much to his upset over the loss of the social-experiment he had grew to love, Crell came to the conclusion that he would probably never see her again and began working for the University of Culat.

Back on Bajor, Wilat was left alone to wander outside the confines of the apartment that had been her home for her entire life and for the first time since infancy, came face to face with other Bajorans. Only knowing Cardassian, she relied heavily on a portable universal-translator as she made her way through crowds of celebrating Bajorans, looking for someone remotely familiar to her.

She found no-one.

Instead, all she found were strangers who cursed the name of her father when she asked them if they knew where Doctor Crell Moset was. Being only 12 years old, she took the hostility towards her adopted-father as being a threat to her as well, and quickly retreated back to her home apartment to hide. After several days of being alone, a group of newly-formed law-enforcement officers were searching the area and found her, taking her back to their base of operations.

By this time, the newly erected Bajoran Provisional Government had came into power and had sighed the Ilvian Proclamation that exiled all Bajorans who had collaborated with the occupation's Cardassian forces. Speaking fluent Cardassian and claiming to be the adopted-daughter of Doctor Crell Moset, Wilat was only exempt from exile because of her young age, instead being placed in the custody of a kindly Bajoran couple who volunteered to look after her.

The couple soon found out the difficulties of looking after a little girl who knew nothing of Bajoran food, custom and culture, and after six months they relinquished custody of Wilat who was quickly placed into a local orphanage. By this time, Wilat had learnt not to mention her association to Doctor Moset, now having some idea of the horrors that had took place during the occupation but not quite believing all of them.

During her time at the orphanage, research made into her past by the administrator revealed very little except for that her family-name had been 'Teryn'. Suggesting that she use that rather than 'Moset', the administrator also began teaching her about Bajoran culture and language, and made sure that she wasn't bullied by the other orphans for being 'weird' (the effects of having never interacted with any other children up until that point).

Just days after the one-year anniversary of the end of the occupation in 2370, Liz and Steven Welford, a human couple, came to Bajor to offer humanitarian-aid as part of their service to a charity organization that was run by the Steven's mother. Shortly after arrival, the two found themselves distributing educational-material at the orphanage that Wilat was staying at and, after hearing of her unique situation, decided to adopt her.

The adoption-process took several months, the request having to be cleared through a Federation Court, and when the official 'go-ahead' was given, Wilat became their legally adopted-daughter. Along with this, she also became a naturalized Federation citizen.

After the adoption, Liz and Steven took Wilat back to their home in England, on Earth, and introduced her to a life that wasn't made difficult by her association to Doctor Moset. Understanding that she had been through enough change as it was, they allowed her to keep her family-name 'Teryn' and nicknamed her 'Wil' as they found her Cardassian-forename harsh to pronounce and didn't think it suited the 13 year old girl.

Wilat quickly adapted to life on Earth, finding British culture and food a lot easier to understand and digest than its Bajoran counterpart. She was also pleased with their replicator's ability to do a fair approximation of many Cardassian foods and drinks, and her Cardassian education made the transition to learning at a human high-school quite easy. Within a year she mastered Federation standard and is now a fluent speaker. Unfortunately, despite all this, she continued to miss the figure that she considered to be her real father - Crell Moset.

Although she was now acutely aware of the horrors that occurred during the occupation, she was convinced the Moset's involvement was innocent. Perhaps the Cardassian government had forced him into doing those things? Perhaps he had been doing them to save Bajoran lives and had no other way to achieve the same results?

By the time Wilat turned 18 in 2375, she had graduated from high-school and, having developed a love of piloting over the years from using flight-simulators in her high-school's student holodeck, decided to enroll in Starfleet and become a professional pilot. It didn't take long for her application to the academy to be accepted and she began training in February of the same year.

Wilat seemed to have a natural skill for piloting and majored in flight-control with a minor in operations. After completing the course she graduated in 2379 with the rank of ensign. It was a wonderful moment in her life and to her it seemed like everything was finally falling into place... until she received a subspace communication from the Chairman of Exobiology at the University of Culat on Cardassia Prime... one Doctor Crell Moset!

Since the end of the Dominion war, Moset had been searching for Wilat through official channels and had finally tracked her down on Earth. Despite the time lost between them, and the fact that his interest in her had started off as an experiment in sociology, he very much still cared for her as a daughter and wanted to meet at Wilat's earliest possible convenience.

After little deliberation with her adopted-parents (Liz and Steven Welford), Wilat boarded a shuttlecraft heading for Cardassia Prime that had been arranged by Moset. Upon arrival, she noticed the way in which people were staring at her and knew at that point that she would never be fully accepted on Cardassia as Moset's real daughter - despite that he was the only father she had ever known.

Her meeting with Moset was uncomfortable at first, both he and her unsure as to how the other had changed in the past six years. As it turns out, Wilat did have some problems with him - primarily his abandonment of her and his treatment of Bajorans during the occupation. Moset addressed both issues, reassuring her that he had no choice in either matter. Wilat was also upset that he had lied to her regarding his so-called 'legal' adoption of her, but he calmed her with the knowledge that no Cardassian court would have ever allowed such a thing, but he nonetheless considered her the daughter he never had.

By the time Wilat left Cardassia Prime two weeks later, she had resolved her issues with Moset and both promised to keep in close contact with each other via subspace. Heading back to Earth, she was given her first assignment by Starfleet Command - a CONN officer onboard the USS Terrain.

On matters not regarding piloting, Wilat is a completely different individual. She is quiet, shy and polite, often choosing to remain in the background during social situations. To those whom she becomes friends with, she is loyal and considerate - but her sarcastic and dry sense of humor (which she developed during her time in England) often cause offense to those who don't know her better.

Wilat is noticeably uncomfortable around other Bajorans. Since she didn't grow up suffering during the occupation, she doesn't share their hatred of Cardassians, nor their worship of the Prophets, and this makes establishing a common thread with them difficult. Quite the opposite, in fact, since she considers one of Bajor's most hated Cardassians to be her father (albeit not in terms of genetics).

Wilat prefers Cardassian food, doesn't wear a Bajoran earring, and doesn't worship the prophets. She suffers from random bouts of claustrophobia and it is recommended that she attend counseling during these periods. Most of the time she is fine, although during a claustrophobic spell rooms that she previously found tolerable suddenly become too cramped and she has an anxiety attack.
