Lex knew from a young age that she was unwanted. In fact, her earliest memory is cowering in a corner, listening to her mother Emilia rant about how much of a burden Lex was. She'd accidentally levitated the milk out of the fridge...and then dropped it.
The abuse continued, and worstened. It wasn't uncommon for Emilia to wake Lex up in the night, screaming, and make her submit to a whipping--but never anywhere anyone could see. Often it was over little things, like Lex leaving her bookbag next to the door or forgetting to rinse out a cup, but sometimes it was just because Emilia had a bad day and Lex was her personal punching bag. The worst time was one of those days, and Lex ended up in the hospital with a concussion because Emilia had straight up flipped her mattress with her on it, and she hit her head on the nightstand.
Lex is pretty sure she was eight when the sound of a drawer handle tinkling, or dishes banging, or someone stomping up the stairs was enough to make her wake up, terrified of what would happen next, even if she was away from home.
Lex never had many friends, just two very, very close ones. She gained a bit of a reputation in fifth grade when one her friends came out as trans and started getting bullied. She had no issue cornering the bullies and verbally threatening them to the point they crapped their pants--or, in one case, ran crying to the teacher. Lex, of course, just said she was defending her friends, but that didn't stop a note getting sent home or the...well.
That summer Lex received a letter from Ilvermorny, for which she rejoiced because it meant most of the year away from home.
At Ilvermorny she was sorted into Wampus, which, quite honestly, was not a suprise. She made beater during her second year and played on the team for the rest of her time there--rainy games were always her favorite.
Academically, DADA was her best class, but potions was her favorite. It was so...so very satisfying to watch her concoctions come together properly.
In the summer before her fifth year, she decided she couldn't take it anymore and ran away from home. She was glad for her neighbors' having let her help out with their horses during the summers, which gave her enough money to actually get away. She broke into a restaurant in downtown Charleston, using its open lookover into the pirate tunnels to actually get into the tunnels. She hung out down there for a week (I am 100% going to hash this out in a mini-fic you have no idea), using her pygmy owl to ask a friend in Indiana if she could stay with them. They'd already said she could if she needed to, but...no harm in double-checking. After she received her reply, she used Point Me (for which she was adequately admonished upon returning to school) to find her way out of the tunnel, and then got directions to the nearest bus station and from there, took a bus to Indiana.
From there, things went very smoothly. She was able to finish school in peace, and from there she got a job at an apothecary, which she enjoyed. She had plans to move to Romania with her girlfriend, an aspiring dragon handler, in a few years, and maybe make potions professionally or be a bodygaurd or something herself.
On Valentine's Day just before she turned nineteen, she had plans to pick her girlfriend up from work so they could get a head start on their romantic weekend, only to find out she'd been caught in the crossfire when one of the animals had gotten a bit too agitated. At the hospital later that night, Lex's girlfriend died.
Later that year she was arrested at a protest after assaulting some alt-right anti-protesters and did a five-year stint in prison for assualt. It was a pretty publicized case, and she certainly didn't plead "not guilty." The judge wasn't exactly impartial, nor was the jury, so she got time but not too much. In prison she took up meditation, which didn't do much more than calm her in the moment.
When she got out, she did a brief stint in the Marines so she could get a good nest egg started. After that she spent time in the northwest, screwing with some white supremacist groups in the area and after, just sort of drifting through college towns, doing mean things to the stupid ones who didn't understand "consent." Along the way she got recruited by an underground organized vigilante group with ties across the States, and some internationally as well.
She spent a good five years working with them all over the country--some of her work included patrolling high-risk areas or hunting down known criminals who had escaped the law, but the group did a good amount of charity work as well. She rose through the ranks of the group quickly due to her initiative, and when she had to move to England because of a mole in the group, she went right into a sister organization in Britain called Vigilance.
With her references from the US, Lex was able to start her work with Vigilance a few steps up. One main difference she noticed after the move was that Vigilance worked primarily in the magical community, whereas the US group didn't focus too much on magical or nonmagical areas.
Six years into it, Lex was the right hand of Vigilance, and spent much of her time doing logistical things, which, while enjoyable, was not her preference, but she was good at it, and she understood that the head was trying to groom her to take his position. The head was off leading a raid on an illegal beast fighting ring they'd been planning for months when he and a few other members were killed by a juvenile dragon they were attempting to subdue so they could transport it. Lex considered it a smack in the face from the universe that she should lose more friends to a dragon, but since leadership of Vigilance had fallen to her, she pushed her feelings aside and focused on filling all the holes and tying up all the lose ends left by the losses.
