## Overview

The Rosier family was rich with stories to tell about Death Eaters, the Dark Arts, and the triumphs of pureblood wizards and witches. Seryna’s parents, Vivian and Cassian, would often try to pass on the stories former generations to two girls, but the small Seryna Rosier would have none of it. She was the anomaly, already a child of rebellion that refused to listen to the horrid stories about mass murders and pureblood supremacy. This led her parents to resent her for most of her childhood. Their emotions didn’t stop them from sending Seryna off to Hogwarts, however, hoping that somehow being around other purebloods would “fix” their little girl.

Seryna’s rebellious nature ultimately landed her in Gryffindor, apart from generations of Rosiers. But the new environment failed to enrich her: while met somewhat with open arms from the Gryffindor students, many still looked at her in fear and disgust due to the reputation of her bloodline. The attitudes of both her fellow students and her family caused the girl to retreat back into expectations, spending more time with like-minded Slytherins and purebloods.

As she aged, Seryna grew tired of pretending. She had to face the fact that she wasn’t like most of the other purebloods— nor did she want to be. Throughout her third year, she distanced herself from the Slytherin group, making up numerous excuses for her absence. That year, Seryna refused to go home for Christmas, sending her parents a strongly worded letter (see here) to inform them before the break. After that, Vivian and Cassian became increasingly aware of the situation, doing anything they could to try and win their daughter back. None of it worked; Seryna seemed as though her mind had already been made up in regards to the Rosier family by the time she returned home for summer break.

Towards the beginning of her fourth year at school, Seryna began dating Phoenix Lovegood in correspondence with fully breaking free of the Slytherin group. She felt better than ever, though this new freedom certainly caused some reckless decisions on Seryna’s part. A long-awaited breakup came to Phoenix and Seryna in late February, largely because of Seryna’s feelings for Harry Potter, though she would never admit it. The breakup only caused her to isolate herself more, pushing away anyone close to her and instead losing herself in the party scene, hooking up with people and coming back to the dorm tipsy. Luckily, her friends didn’t let this get too out of hand, and she was back to normal by the end of the school year.

Her fifth year, Seryna joined Dumbledore’s Army both to strengthen her skills and prove her separation from the rest of the Rosiers. Though she was still met with some of the same looks and hesitance as her first year, she was now strong enough to push past those. Seryna eventually started dating Harry towards the end of the year; that June, she accompanied him and a group of others to the Ministry of Magic in an effort to save Sirius Black. Though Seryna was lucky to escape relatively unscathed, the event certainly brought to light the severity of the war ahead of her, in addition to making her existence known to the Order of the Phoenix.

After a summer of exchanging letters with her friends, most of them detailing how she would do anything to get out of the Rosier mansion, Seryna packed her bags a week before school started and ran away. Mrs. Weasley was gracious enough to allow Seryna to stay with them for the week, and Seryna took her up on the offer reluctantly. The moment she ran away, Vivian and Cassian disowned her and burned her place on the family tree tapestry.

Upon having to leave Hogwarts again after her sixth year, Seryna realized there was nowhere for her to go. She spent a month on her own, taking shelter wherever she could find. She agreed to attend Bill and Fleur’s wedding with Harry in early August; this same night he informed her of the Horcrux Hunt and convinced her not to go with him, instead using her talents to provide support to the remaining members of Dumbledore’s Army once the school year started. After the Ministry fell and the Golden Trio left, Seryna worked with the members of the Order to keep everyone safe. She once again stayed at the Burrow for the remainder of the summer, Molly Weasley having found it absolutely dreadful that she had been on her own the first half of it.

Despite the crushing circumstances, Seryna tried her hardest to keep everyone safe and comforted upon returning to Hogwarts. With the help of Neville Longbottom and Ginny Weasley, she organized occasional Dumbledore’s Army meetings, though these lifeless meetings dwindled down to only a few people and they had to call it quits. A few weeks later, the members of Dumbledore’s Army began to move into the Room of Requirement per Seryna and Neville’s idea. With the help of Seraphina Fawcett and a few other individuals, a sort of society was built— complete with hammocks and mattresses and tents and later on, a system of communications to reach even the Order of the Phoenix.

Seryna, unfortunately, underestimated the lengths to which Voldemort would go to to defeat Harry Potter. In the middle of a Hogsmeade run to get food for the group, Seryna was taken by a gang of Snatchers accompanied by her ex-boyfriend Phoenix. After a day of questioning and beatings, Seryna was transferred to the Ministry of Magic. She was again interrogated, though this time by Death Eaters and this time through the usage of the Cruciatus Curse. Two days and one night in captivity passed before Seryna was rescued by Sera, Neville, Ginny, Leighton, and Phoenix.

The Battle of Hogwarts rolled around soon enough, and Seryna was ready for it. Despite some close calls, she was fortunate enough to make it out alive— though seriously shaken by watching her father die, thinking Harry to be dead for several hours, and her own desire to kill in the midst of the battle.

Seryna went on to marry Harry Potter and have three lovely children, eventually succeeding Filius Flitwick as Hogwarts’ Charms Professor in 2017.

## Years at Hogwarts

### First Year

Seryna arrives at Hogwarts with great expectations, thinking of it as a way to escape the pressure of being a Rosier. However, it became apparent very quickly that this would be more difficult than expected.

On the Hogwarts Express, Seryna hit it off with a young girl named Sayaka Belledeau, who would later become her roommate. The two had been talking, laughing for some time before Ivy Parkinson found her, beckoning her away, looking Sayaka up and down before giggling and walking away. Seryna was practically forced to follow, muttering a small apology before leaving her new friend.

At the Sorting Ceremony, Seryna was riddled with nerves. On the one hand, she expected Slytherin, as every other Rosier had historically been. But on the other hand, she already knew at her young age that she didn't quite fit in with the rest of the Rosiers. She didn't know what to feel when she was sorted into the house of Gryffindor, the brave and the courageous. As she walked towards the table adorned with red and gold decorations, she caught a look of disbelief on Stella Rosier’s face. She plastered on a bright smile, taking an open seat next to Sayaka, a familiar face among many unknowns. Seryna watched with wide eyes as Stella happily became a part of the Slytherin house, among the rest of their childhood friends. She was in some part relieved to be free of them, but also afraid of what would happen should she lose all of them for good.

Gryffindor had not been what she expected. While Seryna was met with smiles and congratulations from most current Gryffindor students, she was also keen to noticing the opposite reactions. She watched as people gave her dirty looks in the common room, heard them whispering about her, eyes widening in fear at the sight of a Rosier. She was given her room assignment, soon meeting Drew Ambrosi and Leighton Messner along with the girl she had spoken to on the train, Sayaka. The four hit it off quite quickly, immediately finding friends that would last them a lifetime.

Seryna worked hard to push through the challenges her first semester, those specifically being how she was clearly mistrusted by most of the Gryffindors and seen as a traitor by the pureblood Slytherins she spent her childhood with. She felt as though she couldn't win -- being herself among Gryffindors only made her feel unwelcome, but to fit in with the Slytherins she had to be someone she wasn't. This made her first semester incredibly difficult, bouncing back and forth between two groups and trying to find herself in the process.

Eventually, the students went home for Christmas. Seryna kept quiet as she returned to the Rosier house, barely talking to even Stella. She obviously had to reveal the fact that she had been sorted into Gryffindor, much to the disappointment of Vivian and Cassian Rosier. They barely spoke to her after that, their contempt for their daughter extremely clear. Although Seryna liked to pretend she had little regard for her parents' opinions, it hurt her in truth. she didn't *like* feeling like she had failed them, even if there was nothing she could have done about it.

When Seryna came back to school after the holiday break, she was endowed with a new ambition to fulfill her parents' expectations. She devoted most of her time to being with her Slytherin friends, quietly watching as they bullied others and bullied each other. She was fortunate enough that she stayed out of most of their drama, just following silently for the remainder of her first year. She grew quite apathetic in the process, it being the only way to survive watching them again and again be horrible to the people who weren't like them.

### Second & Third Years

Seryna returned for her second year of school in a similar position as when she left the previous year. She had great intention to prove herself to her parents, and was not yet aware of how much it was taking a toll on her mental health. She continued to stay alongside the Slytherin girls as they wreaked havoc on anyone who looked at them the wrong way, though she rarely participated. As her Gryffindor friends tried to bond with her, Seryna didn't necessarily stop them, but she certainly wasn't the one to start the conversation or invite them somewhere. Nevertheless, she grew closer with them every day, those people eventually being what would give her the strength to break free. Her third year was quite similar, dragging on the attitude she had towards the people she spent time with. She fought back a little bit more, refusing to watch Ivy or Sage bully a first year, refusing to go play a trick on someone with them. Luckily, Sage Carrow had realized how much the friendships Seryna had were affecting her, and began to help Seryna— backing up her lame excuses for not hanging out with the girls or taking their attention off Seryna’s absence by arguing that the Rosier girl wasn't "bad enough" or "evil enough" to be included.

### Fourth Year

Seryna’s fourth year was quite the turning point in regards to her experiences at hogwarts. After a summer filled with burying herself in the library and constantly sending letters to her real friends, Seryna was moved to fully separate herself from the Slytherins girls. This was made even easier as she began dating Ravenclaw Phoenix Lovegood at the beginning of the year, often using him as an excuse to not hang out with them. Eventually, she grew so far apart and distant that they ignored her being gone, marking an official separation by the time the Triwizard Tournament rolled around.

Throughout the course of the year, she thrived for the first time in social events. Finally having realized who her true friends were and being courageous enough to fully devote her time to them instead, she grew into quite a lively person. It was visible how much she had changed without the influence of the Slytherin girls, even standing up to them if they targeted her friends.

It was somewhat ironic that the way in which Phoenix and her met was through them both being purebloods, hanging out around the same people for several years. It was widely joked about among their friend group that they should have been a couple, though it took awhile for Seryna to come around to that idea. Eventually, they started dating within the first month of their fourth year of school. Their relationship was quite perfect on the surface, two attractive young people always seen laughing together and not being able to keep their hands off of one another. They were many of each others' "firsts" that year, guaranteeing each a forever special place in the other's heart. Seryna could have imagined a future with him, had it not been for the existence of Harry Potter. The Chosen One proved a challenge in their relationship. Seryna had always harbored unresolved feelings for the boy, though she expected if she suppressed them enough they would eventually go away. Amonth or two with Phoenix was enough to make her forget about it temporarily, though her and Harry never stopped talking despite her new relationship. Seryna messed up severely the day of the first task in the triwizard tournament, impulsively kissing Harry right before the event. Much to her misfortune, Rita Skeeter had captured a picture of it, landing her and Harry on the front page of the daily prophet for all of Hogwarts to see. Despite being called a cheater and a slut daily by fellow students, Seryna was forgiven by Phoenix a few days later, though nothing would be quite the same after that.

The Yule Ball rolled around, followed by the second task of the tournament. Seryna had been summoned by Professor Minerva Mcgonagall for unknown reasons, which she would only find out several hours later when she was pulled above water by Harry Potter, the two climbing breathlessly onto the dock. She was quickly informed by a student that for that task, each champion had been required to save the person they cared about the most, Seryna being that person to Harry. mere minutes after being saved, Seryna found Phoenix, who broke up with her unable to handle the budding relationship between her and Harry.

Between the breakup in February, her confusion about her feelings towards Harry, and eventually the tragic death of Cedric Diggory, Seryna began to lose herself in the party scene. Despite being closed off from most activity after the breakup, she quickly realized this wouldn't do anything to help, instead distracting herself with alcohol and hookups at house parties. She was lucky this never got out of control, however, and was a relatively short-lived phase, ending simultaneously with the end of the school year.

### Fifth Year

Seryna spent her summer at the Rosier Mansion as usual, now prone to outbursts at her parents or refusals to attend their pureblood parties. Her and Phoenix Lovegood, bored and lonely, had been exchanging letters, though agreed when they came back to school that they planned on staying friends.

Meanwhile, Dolores Umbridge was slowly gaining more and more control of Hogwarts, which especially affected those wanting and willing to defend themselves should a war be upon them soon. She heard all about Umbridge's methods of punishment she inflicted upon Harry Potter for talking back, most importantly the usage of the Black Quill. Seryna was even forced to use it a few times as a result of her standing up to Umbridge during class, primarily over the fact that they were not actually being taught how to defend themselves against the Dark Arts.

Courtesy of the Golden Trio, Dumbledore’s Army was founded soon enough. Seryna joined, of course, though met with many looks of distrust and disapproval from those members who didn't yet trust anyone with the last name Rosier. She proved herself once again to be a talented witch, learning a variety of spells. She discovered her patronus to be a dove, representing hope and salvation during difficult times.

For the first time, Seryna stayed at Hogwarts over Christmas break, finding company in whoever else was there. They all exchanged presents, ate together, and Seryna was happier than she had ever been back home. Following the return from break, Saruman Noaks delivered a letter from Vivian and Cassian Rosier, talking about how much they missed her and wished she would come home. Although Seryna felt guilty for causing them pain, she still didn't falter, knowing she had made the right decisions for herself.

The relationship between her and Harry Potter became quite strained that year, as Harry used fellow Dumbledore’s Army member Cho Chang as a way of hiding his feelings for Seryna. However, it did not appear that way to Seryna, causing the tension between the two of them to heighten. Regardless, she still cared about him greatly, and for that reason accompanied him along with Ron Weasley, Hermione Granger, Neville Longbottom, Ginny Weasley, and Luna Lovegood to save Sirius Black from the dark lord. Though Seryna fought hard, she was obviously no match for experienced Death Eaters, the entire group having to be saved at the last minute by members of the order. Seryna watched as the only family Harry had was taken away from him. as he ran to catch Bellatrix Lestrange, Seryna screamed at him from her place not to kill the witch, knowing it would haunt him for the rest of his life if he had.

The group returned to Hogwarts, fortunately with no major injuries. However, the loss of Sirius Black affected them all, Harry especially. Seryna was forced to face the fact that a war was coming, and she and her friends were certainly not prepared for its consequences. This only filled her with a new sense of determination for the rest of the year, entirely intent on bettering her skills to fight when the time came.

### Sixth Year

After a summer of exchanging letters with her friends, most of them detailing how she would do anything to get out of the Rosier mansion, Seryna packed her bags a week before school started and ran away. Mrs. Weasley was gracious enough to allow Seryna to stay with them for the week, and Seryna took her up on the offer reluctantly, not wanting cause her any further stress but also knowing she had nowhere else to go. The moment she ran away, Vivian and Cassian disowned her and burned her place on the family tree tapestry.

Within the first week back, Seryna got herself into quite the situation at the back-to-school bonfire. This consisted of multiple fights, both verbal and physical, with former friends Ivy Parkinson, Sage Carrow, and Saruman Noaks. She was proud of herself for standing up to Ivy after the Slytherin girl had attacked her and her friends, though her adrenaline soon pushed her to pick another fight that night. This one was with Saruman, who would go on to say things so harsh that seryna felt utterly broken after the night's events. She sulked around for the better part of two weeks, before eventually returning to her regular self as she realized the opinions of her former friends truly did not matter.

After that, the year became quite uneventful for Seryna. It consisted simply of practicing magic, partying, and spending time with her best friends and lovely new boyfriend Harry. Seryna excelled this year, finding herself in a position where she had everything within her heart's desire all at once, not to mention the threat of a Second Wizardng War was rarely brought up now. Seryna could, at least temporarily, forget about its existence and the threats that approached.

Though, this sense of safety didn't last long. Throughout the year, despite leaning towards the side of optimism, Seryna was still aware of her surroundings. More specifically, she was aware of the way that Draco Malfoy followed her and Harry practically everywhere. She would catch him lurking in the shadows, or sneaking around the corner, not quite tailing the two but certainly around enough to where it couldn't have been coincidental. Seryna completely believed Harry's theory that Draco had become a death eater and would do anything to prove it, even getting in trouble herself by Severus Snape or someone else for sneaking around the castle after hours.

This mission of hers to prove Draco's loyalty hit a wall the night of June thirtieth, which would go down in history as the day headmaster Albus Dumbledore would be murdered by Snape. Several hours prior, Seryna had overheard Snape and Malfoy talking, and gathered enough clues from their conversation to suspect they were going to kill Dumbledore. However, she had also heard that multiple Death Eaters would be storming the castle tonight, presumably to help with that task, so Seryna knew she would need backup if she was to fight to stop them. on the way to find Professor Minerva Mcgonagall, she ran into Sage Carrow, whom she caught packing a suitcase to leave with the Death Eaters at the end of the night. After locking Sage in her room without much of a plan, Seryna ran to Mcgonagall, but it was too late. she had already received word that Dumbledore had been killed, the Death Eaters making their way out of the castle at that moment. It would not be right to try and stop them, only putting more students in danger which was the last thing that Dumbledore would have wanted.

Seryna reunited with Harry at Dumbledore's open casket, finding him knelt over the headmaster with sobs wracking his body. She comforted him for many minutes before forcing him to stand up, the two walking slowly back to the Gryffindor dormitories.

### Seventh Year

Seryna had to leave Hogwarts for the summer, but there was nowhere for her to go— not the Rosier mansion, not to the homes of any of her friends’, fearing she would only be a burden, and not to the Order, who she wasn’t sure fully trusted her. Consequently, Seryna resolved to live on her own for a while, feeling that it was the best solution especially since she was of age and could use magic legally outside of school. She stayed in various places, among them the Leaky Cauldron for a few nights or Muggle hotels, and was even able to visit Harry a few times while he was with the Dursleys. She agreed to attend Bill and Fleur’s wedding with him in early August; this same night he informed her of the Horcrux Hunt and convinced her not to go with him, instead using her talents to provide support to the remaining members of Dumbledore’s Army once the school year started. After the Ministry fell and the Golden Trio left, Seryna worked with the members of the Order to keep everyone safe. She once again stayed at the Burrow for the remainder of the summer, Molly Weasley having found it absolutely dreadful that she had been on her own the first half of it.

Several weeks later, she went back to school knowing this year would be more difficult than anything she had faced. With Severus Snape now headmaster, Hogwarts lacked its usual charm. It was gloomy, frightening especially to the students who had bravely chosen not to ally with Voldemort and the Ministry that now rested under his control. Although Snape never explicitly addressed his allegiance to the dark lord, everyone knew where his loyalties lied-- and that the whole of Hogwarts was worse off because of it.

Seryna did her best to follow Harry's wishes of keeping Dumbledore's Army intact, doing so by hosting biweekly meetings just to gather and check in with everyone. However, it was clear these meetings were not doing much to lift anyone's spirits, as Seryna couldn't exactly give any motivational speeches when she had such limited knowledge of the situation at hand and absolutely no plan. She was a supposed leader armed with nothing to support the people she was leading, causing several members of the group to distrust her. Not to mention her being a Rosier invoked skepticism among them, even though Seryna had assured everyone of her being disowned the summer before.

Eventually, Seryna realized her current system of occasional meetings and hoping for a miracle wouldn't suffice. Hogwarts was growing more and more dangerous, especially for the Muggleborn witches and wizards or those considered blood traitors (which included seryna). They needed a safe place, somewhere within Hogwarts that would allow them to speak freely and see their friends and practice their magic in preparation for the biggest fight of their lives.

The Room of Requirement obviously came to mind. With the help of Neville Longbottom, Seryna managed to access the room in early December and turn it into a haven of sorts-- complete with hammocks and mattresses, medicine and first aid equipment, and sources of light where they were needed. as people began filtering in, trusting Seryna and expecting that trust in return, a small society was built. Job assignments were given, and a system of communications was created to keep lookout for people like Snape or other Slytherins who answered to him. The room became a safe place for dozens of students during such a difficult time period.

Christmas break rolled around, and Seryna was fortunately able to go back to the Burrow for a short time. What inevitably followed her presence were the questions of whether or not she knew anything about the Golden Trio’s whereabouts or status, as they couldn't speak through letters while Seryna was at Hogwarts for fear of them being intercepted. She was forced to tell them she knew just as much as they did, only that he had set off with Ron and Hermione to finish Dumbledore's mission hunting Horcruxes. Everyone was disheartened at the fact that Seryna couldn't tell them anything else, but the fact was that she hadn't seen or spoken to Harry since August. She didn't even know if he was alive at this point, though forced to hold onto hope knowing that her world would crumble if she didn't.

Students returned from break to the now-familiar somber castle. Tensions were at an all-time high, and it was visible among the students and even the faculty. But Seryna had other things on her mind, specifically how they would continue on with living in the Room of Requirement. She noticed after the break that a portrait had appeared in the room, which they would later discover to be the late Albus Dumbledore's sister, Ariana. After some exploration, Neville discovered it was a passage to Hog’s Head and Aberforth Dumbledore, who was kind enough to smuggle them food through the passageways. Seryna occasionally took on the job of gathering said food, only doing so because it was an opportunity to access the world outside of Hogwarts— even if it was just walking around Hogsmeade and grabbing a butterbeer for an hour. One day, sometime at the end of February, Seryna had spotted a familiar face lurking around the corner of Hog’s Head, none other than her ex-boyfriend and current friend Phoenix Lovegood. He hadn't been at school yet that year, though Seryna was unsure why. She hadn't gotten the chance to ask him before, and she certainly wouldn't pass up the opportunity now. She approached him, the two talking though Phoenix was clearly nervous about something. He tried to get away from her, but Seryna wouldn't budge, insisting he tell her what was wrong. But the next thing she knew, she was trapped by a gang of Snatchers behind an alley, with Phoenix holding her back from escaping. After several minutes of taunting, Seryna was knocked out cold.

She awoke God knows how many hours later in a house in the woods, presumably a Snatched base. Tied to a chair, Seryna was questioned about numerous things, though they all revolved around her knowledge of Harry Potter and his whereabouts. She couldn't give answers to many of their questions, mostly because Harry genuinely hadn't told her much— and even if he had, there was no way she would have spilled his secrets for a chance at her own survival. She was beaten each time she didn't provide what they deemed a good answer, as was Phoenix a few times when he attempted to stop the Snatchers. Seryna was tossed into a cell for the night, hearing whispers about how they would deliver her to the Ministry in the morning.

And they didn't disappoint, Seryna being swiftly taken to the Ministry of Magic at dawn the next day. She was interrogated without mercy by two Death Eaters, one she knew to be Sloan Yaxley’s father. They questioned her about the whereabouts of Harry Potter, what his plans were, who he planned to attack next. Again amidst sobs and pleas to let her go, she told them she knew nothing. Soon, they grew tired of that excuse and began to torture Seryna, using the Cruciatus curse on her several times. There came a point where Seryna could barely feel anything but pain, ripping through her body as she screamed desperately for mercy. She again was tossed into a cell, four grey impenetrable walls and a mattress in the corner before the same thing occurred the next day.

After two days and two nights held captive by the Ministry, Seryna was fortunately rescued by a team of members from Dumbledore’s Army including Sera Fawcett, Leighton Messner, and Neville Longbottom, who were surprisingly joined by both Stella Rosier and Phoenix Lovegood. Though resisting Phoenix's attempts to help her at first, the sight of the rest of her friends convinced her to let them save her, sprinting through the Ministry and likely killing several Death Eaters in the process. they managed to make it back to Hogsmeade, some apparating and some through the usage of floo powder to reconvene at Hog’s Head. There, they safely re-entered the Room of Requirement, Though Stella had to go a separate way into the castle not being a part of their student organization.

Seryna was welcomed back with warm smiles and hugs before being placed in the tents that acted as a makeshift infirmary to the group, providing the wounded with temporary privacy. Though Seryna insisted it wasn't needed, her friends essentially outvoted her. Within the next few days (which had mostly been spent sleeping), she had already begun to return to her normal self. In fact, Seryna was a little *too* normal, faking laughter and forcing herself to eat and go to class on a daily basis. To the outside eye, it would have seemed like nothing even happened to Seryna— and that's what worried her friends, especially since in earlier years her coping mechanisms had usually consisted of cutting herself off and shutting down completely. But this time was different, they noticed. Seryna no longer allowed herself to be vulnerable, believing if she let everyone see her broken that the entire rebellion they had built within Hogwarts would soon follow suit. So Seryna continued with her façade, until Drew Ambrosi returned to the school and was able to snap Seryna out of it, assuring her that she wasn't alone and didn't have to carry the weight of everything by herself.

Seryna tried her hardest to keep everything running, and to keep everyone's spirits up in the process. But with no news on what was happening outside of the stone walls, it was clear that they were losing hope. The mood had shifted from the excited adrenaline rush of a rebellion to the fear of being defeated despite their efforts. They possessed no knowledge of the Golden Trio’s success, no communications to the older and more experienced order, and no clue when Hogwarts would be hit, forcing them into the fight of their lives.

Around late March, Seryna finally received a good piece of news. The next time she went to Hog’s Head, this time accompanied by two friends, Phoenix Lovegood was waiting to inform her of his recent experiences. He told her that his sister, Luna Lovegood, had been kidnapped along with Garrick Ollivander and Griphook, taken to Malfoy Manor. However, they had been saved by Dobby the elf, under the instruction of none other than Harry Potter. He was, indeed, alive-- news that would save Seryna and the entire rebellion. She returned to them, sharing what she had been told but also expressing the importance of keeping that news confined to the group. It wouldn't do them any good for someone like Snape to find out that Harry was alive and well, and thus so was the Horcrux Hunt.

The next month or so was spent in preparation for inevitable battle. They practiced spells on each other, similar to how Dumbledore’s Army had functioned during Seryna’s fifth year. They upgraded internal communications, set new schedules, taught themselves curses and hexes. The excitement of the fight had been restored, everyone grateful to feel like they were fighting *for* something.

Soon enough, the fight had reached them. On the first of may, the Golden Trio climbed through the painting and greeted Dumbledore's Army, all with smiling faces looking up at them. Seryna and Harry were able to reunite quickly after nine months apart, no time to catch up on either's adventures before Ginny Weasley rushed in, informing everyone that Snape wanted all students in the great hall. Seryna, however, stayed behind, knowing the Order would be on their way any second. As her friends, including Harry all went down to the Great Hall, she reunited with the Order for their entrance. Seryna burst into the Great Hall alongside them several minutes later, displaying their support for Harry and the cause. After Snape's exit, Seryna followed Minerva Mcgonagall to do whatever she instructed in preparation for the battle.

Seryna Rosier fought harder than she had in her entire life. She felt as numerous hexes and curses left her wand, almost automatic, without thinking. She couldn't afford to stop and think. She couldn't think about how she was taking literal *lives* away, even if they were Death Eaters. She couldn't think about how a false move or a hesitation could mean her death or the death of a friend. There was no thinking, just acting.

In the heat of the battle, she spotted a familiar face across the field. It was her father, caught in a one-on-one duel with Professor Flitwick. She watched as the two fought, unable to tear her eyes away as Flitwick finally bested her father, sending him flying through the air thanks to a Confringo curse. She couldn't help but feel her feet carry her to her father, ignoring her surroundings as she knelt beside him. Upon impact from falling back down, Cassian Rosier had hit his head incredibly hard, blood seeping from the wound. He was bleeding out, Seryna knew. as much as they had been distanced in the past few years, Seryna couldn't help but still care about him— he was her father, after all. she didn't speak, just tried to reach for his hand before he yanked it away. He acted as though she was a stranger, foreign to even his own memory.

"You are no daughter of mine", he had said before his body went limp. Seryna fought back sobs for a moment before something exploded behind her, demanding her attention. She pulled herself away from her father's dead body, returning to the fight.

She didn't realize what the battle would cost her, cost all of them. Her senses were dulled as she walked through the Great Hall, which had been silently agreed upon as the congregation point for the one-hour armistice that Voldemort had granted them. She heard muffled screams and sobs as people found their friends dead, she heard healers running to help. Her eyes glazed over the bodies that littered the floor, tearing up at the sights of Remus Lupin, Nymphadora Tonks, and Fred Weasley, all of whom had become somewhat like family to her. After Harry discovered at the Pensieve that he had to sacrifice himself in order to defeat Voldemort, the two shared a brief moment in the Great Hall. He didn't tell her directly of his intentions, but Seryna could see it on his face. She immediately broke down, pleading with him not to go. but it was no use— Harry had to leave, while a screaming Seryna was held back by Mcgonagall.

Soon enough, Voldemort's voice rang throughout the area once again, the survivors rushing out to see what had happened. Seryna pushed her way to the front, needing to see it for herself. She was met with the sight of Harry's limp body in Hagrid's arms, a horrible scream immediately leaving from her mouth. A few students, one of whom Seryna had never even met before, pulled her back, wrapping her in their arms. They tried to soothe her so as not to draw attention, meanwhile Seryna muffled her cries and looked up at the scene through tearful eyes. He was dead. And what was even worse was that Voldemort still stood. The moment Seryna had given up, truly given up, Harry fell from Hagrid's grasp to everyone's surprise, immediately escaping the scene.

The battle ensued once again, Seryna restored with a new fight within her knowing that they still had a chance to defeat the dark lord. At some point, she quite literally ran into Neville Longbottom, who informed her of his responsibility to kill the snake Nagini. She agreed to help him, leaving the main battlefield to search the castle. The two ran through the corridors until finally finding the snake, which was eagerly slithering towards her two friends Ron Weasley and Hermione Granger. Out of the corner of her eye, she spotted something glimmering in the Sorting Hat, which laid torn and ripped on the floor. Moving closer, it revealed itself to be the sword of Gryffindor. Alerting Neville, she quickly tossed him the sword before watching him slice through Nagini with a single stroke of the blade, rendering Voldemort mortal for Harry to kill him.

One would have expected a sign when the dark lord fell. A piercing scream, or a flash of light. but there was nothing— just a feeling. it *felt* like the fight was over. Seryna could see it on the faces of her friends as they slowly stood up, on the grim faces of Death Eaters as the realization dawned on them, on the faces of the Malfoys as they ran like cowards away from the scene. The fight was over.

Seryna returned to the Great Hall with Neville, assuming everyone would return there. she was right— the Weasleys, her professors, fellow students all rested, finally. It was unusually quiet, everyone just grateful for the company of their loved ones without feeling the need to disrupt the peace. Seryna couldn't relax, though, not without confirmation that Harry was alive.

She received this confirmation soon enough, as Harry walked through the Great Hall until they finally spotted each other. Seryna gasped, though this time it was one of relief before she ran to him, the two embracing for quite some time. She had never felt safer than in that moment.

Several weeks later, things went back to somewhat normal. McGonagall assumed the position of headmistress at Hogwarts, and the castle was restored to its original glory with the help of many professors and former members of the Order. Seryna had stayed at the Burrow for the time being, though it felt quite somber as the Weasleys reeled from the death of one of their own. She returned to Hogwarts only to take her OWL's and gather whatever possessions of hers hadn't been destroyed during the Battle of Hogwarts.

Seryna left the castle for the summer, and thus ended her story as a student at Hogwarts School of Witchcraft & Wizardry, as well as a valiant warrior in the Second Wizarding War.

## Physical Description

    Seryna has often been described as a beautiful young woman, taking after her mother's looks. She has blonde hair that gets longer throughout the years, naturally straight but often styled with loose waves. She has striking green eyes, accompanied by sharp facial features. This is where the Rosier blood in her really shows through, as many have been noted to have prominent cheekbones and jawlines. Seryna is shorter than most, standing at five feet and three inches.

Seryna bears several scars from the Battle of Hogwarts, which have faded slightly but remain a reminder of her past.

## Personality

Seryna Rosier could be described as a flame. brilliant, captivating, full of energy and life— and at the same time, set off by the smallest thing, uncontrollable. She’s fierce in many capacities, a friend who would defend you to her dying breath and a daughter unrestricted by the expectations that precede her. She doesn’t enjoy starting fights, though can be easily swept up in one especially if it comes from someone she doesn’t particularly like. Once they ignite the fire, Seryna knows no boundaries. As a Gryffindor, she unsurprisingly possesses the characteristics they are known for. She’s wildly courageous, enough to defy generations of Rosiers but also enough to get her into quite a bit of trouble when courage quickly blurs into recklessness. Above all, Seryna is constantly seeking to be better. Letting herself be vulnerable to those she trusts, learning and absorbing as much information as possible, apologizing for her wrongs and allowing herself to forgive those who have wronged her. And the mission taking up the majority of her first seventeen years of life: defying the supremacist ideals that the Sacred Twenty-Eight bloodlines were infamous for. To be a better person— that was Seryna’s goal, and always would be.

* Courageous, daring, reckless
	+ The traits of a typical Gryffindor, and Seryna possesses all of them. She is the first to step into an anxiety-inducing situation, or the first to volunteer for something unknown. She knows little fear, and even then they prove to be more on the emotional side rather than physical frights. This courage, however, dances the line of recklessness. Seryna often gets caught up in the adrenaline boost that her adventures provide her, getting her into numerous situations that bring sudden consequences. At some points, she's forced to confront herself and recognize how her recklessness has effects, though she fails to ever really make an improvement.
* Rebellious, defiant, outspoken
	+ Generations of Rosiers had built a strong mold for the girl to follow, one of Slytherin descent and pureblood supremacy. Seryna saw through this relatively quickly, and though at her age she couldn't do much to defy it, she certainly avoided playing into these attitudes. Although her first few years at Hogwarts brought about challenges that caused her to fall into the same ideals as her family, she eventually grew a strong sense of rebelliousness enough to make her break free of what she was conditioned to think. She was more willing to openly reveal her thoughts and not apologize for vocalizing what she truly believed in. The defiance she exhibits against her family and their traditional values is extremely apparent in her fourth year of school, when she refuses to return home, then in years following as she finds her home among the Gryffindor students.
* Hot-headed, dramatic, impulsive, defensive
	+ It is quite easy to get a rise out of Seryna Rosier, and during her later years at Hogwarts, she's likely to act upon these emotions. She is quick to get upset over something or to lose her temper, resulting in a lot of instances where she talks or acts without thinking. Though she's not one to start a fight, she will certainly escalate it to a great extent once she has been provoked, resulting in a lot of petty arguments turning into full events that make everyone in the room stop and watch. It is likely her impulsivity will lead her to say something she doesn't mean to a friend, though she's usually able to recognize her mistake and apologize for it soon after she's calmed down. Seryna has a habit of making a scene, even though she doesn't mean to most of the time- a naturally loud voice and defensive attitude are to blame for that.

## Magical Abilities

Seryna has always been credited as quite a talented witch, even though it may not appear so at first. Given the numerous spellbooks she would bury herself during the times she was unwillingly stuck in the Rosier mansion, she learned many spells in advance so that when she got to Hogwarts the following year she would always be ahead of the game. She was one of the first within Dumbledore's Army to produce a corporeal Patronus, a feat that not many others achieved quite as quickly. Furthermore, Seryna's leadership role during her seventh year required her to tutor and teach many younger students, only strengthening her abilities.

* **Charms**: Seryna is especially proficient in charms, or spells that add certain properties to an individual or object. These kinds of spells usually focus on altering what an object does, in comparison to Transfiguration, which alters what an object is. Her first year, she was one of the quickest to master the basic charms including the Levitation Charm, Wand-Lighting Charm, and the Knockback Jinx. She was bested really only by Hermione Granger, though felt no animosity towards her because of this. Seryna learned many more charms over the years, even in her fifth year through Dumbledore’s Army. She would often help fellow members with charms such as the Reductor Curse or Fire-Making Spell. With the help of the Order of the Phoenix, she went on to learn extremely difficult charms, most of which doubled as spells to defend herself against the Dark Arts. They came quite in handy during the Battle of Hogwarts, where Seryna relied on her extensive knowledge to stay alive and keep herself and her friends safe. After the Battle, when Seryna returned briefly to take her OWL exams, she received an Outstanding in Charms. This was the only class she had achieved such a high score in, and alerted her once again to her proficiency in this topic. She would go on to become the Charms professor in 2014, passing on her knowledge and serving as a guiding figure for many young witches and wizards.

* **Flying**: Seryna is also particularly talented with a broomstick, shown in her first few years in Flying Class. She made it onto Gryffindor’s Quidditch team as a secondary Chaser her third year, though promoted to starting Chaser her fourth year. It is unclear as to whether she would have made the team her first or second year, as Seryna was too scared and preoccupied with social drama to try out. Her skills flying are ultimately what lands her a place in the Battle of the Seven Potters. She was only allowed to participate by the leaders of the Order because they were familiar with how useful she could be, able to cast spells and fly simultaneously.

* **Defense Against the Dark Arts**: Though not as proficient here as she was in Charms, Seryna certainly does not fall short when it comes to Defense Against the Dark Arts. The Rosier mansion certainly housed less spellbooks about countering these spells, instead favoring the actual practice of the Dark Arts itself. When Seryna got to Hogwarts, she was eager to learn about what would save her from the Dark Arts that her family practiced, though it became clear quickly that the teachers were poorly qualified and poorly trained. She took to the library as a result, often attempting to teach herself spells that she wasn’t quite grasping during class. Her fifth year rolled around, marking the year that students were not even being taught how to defend themselves, which infuriated Seryna to a great extent. She joined Dumbledore’s Army because of this, finally learning spells such as the Reductor Curse, Stunning Spell, and the Patronus Charm. Seryna was one of the first members to succeed in producing a corporeal Patronus, finding its form to be the dove. Later on, most of her training in fighting the Dark Arts came from members of the Order of the Phoenix, who were extremely well versed and experienced. They taught Seryna everything she needed to know in preparation for the battles to come, and helped her survive through it all. After the Battle of Hogwarts, Seryna returned to secure an Exceeds Expectations on her OWL exam.

* **Herbology**: Seryna does not understand herbology. Next.
