Lyra Euphemia Potter (born 31 July 1980), also known as Lyra Hope Lupin, is an English half-blood witch. She is the only daughter of James and Lily Potter (née Evans), and the twin sister of Harry Potter. Lyra's birth was not overshadowed by a prophecy, unlike her brother and another boy, Neville Longbottom, who could defeat Lord Voldemort, the world's most powerful and feared dark wizard. After half of the prophecy was delivered to Voldemort with Severus Snape's consent, Harry was chosen as a target due to his many similarities to the Dark Lord. This, in turn, caused the Potter family to go into hiding.

Before events fully unfolded, James indicated to Remus that he would accept Lyra and raise her as his own. Lily was originally against it, but ultimately approved. On Halloween night in 1981, just before Lord Voldemort came to Godric's Hollow, Remus appeared there. James offered Lyra to him to defend her from the Dark Lord. Later, after Remus fled with the newborn Lyra, Voldemort reached them and slaughtered their parents when they attempted to shield Lyra's brother, but this failed attempt to slaughter Harry led to Voldemort's first defeat. This climax celebrated the end of the First Wizarding War, and Harry became known as "The Boy Who Lived" from then on, as he was the only known survivor of the Killing Curse, magically protected by his mother's loving sacrifice. According to the terms of the foretelling, this attempt on his life made him, not Neville, Voldemort's rival.

Thanks to the flattering magic of his mom, who surrendered her life for Harry, the Dark Lord's curse was reflected off Harry and killed him instead. Albus Dumbledore then passed Harry into the care of his hateful Muggle family, Vernon and Petunia Dursley. Under their care, he was shielded from Lord Voldemort, thanks to the Blood Bond spell. Lyra was appointed to James' best friend, Remus Lupin. To ensure her safety from Voldemort, Lyra was placed under the defensive magic of the Fidelius Charm.

Background

Early life (1980 - 1991)

Lyra Fleamont Potter was born on 31 July 1980 with her twin brother Harry, at Godric's Hollow in the West Country, England, only hours after her future classmate Neville Longbottom. Around this time, a foretelling about a boy born at the end of July with the power to beat Voldemort was communicated among wizards. Lyra and Harry's christening was calm and short, with only mother, father, Sirius Black, and Remus Lupin in attendance. Lyra spent her babyhood in disguise with her parents and brother in the Potter cottage.

For Lyra's first birthday, Remus bought her a soft and cuddly plush husky. Lily's letter to Remus mentioned that this plush had been Lyra's favourite present. Lily and James also hosted a very quiet birthday tea. The only ones in attendance were them, Harry, Lyra, and Bathilda Bagshot, who also used to dote on newborn Harry and Lyra. The Potters had a cat, but what happened to it after Voldemort's attack remains unidentified.

When it became clear that Voldemort marked the Potters for demise in regard to the foretelling, Albus Dumbledore implied that they use the Fidelius Charm to keep them safe. He even suggested that he be the Potters' Secret Keeper, but the Potters had already prepared to make Sirius their Secret Keeper instead. On Sirius's direction, they changed this identification to Peter Pettigrew, who they thought would be less distrustful. In a horrible turn of fate, Pettigrew was a Death Eater spy and backstabbed the Potters' whereabouts hardly a week later.

Invasion at Godric's Hollow (1981)

Before any events fully developed, James proposed that Remus take Lyra and introduce her as his own. Lily originally opposed this but eventually approved. On Halloween night in 1981, just before Lord Voldemort arrived at Godric's Hollow, Remus appeared there. James handed Lyra to him to shield her from the Dark Lord. Later, after Remus departed with the infant Lyra, Voldemort arrived, killing James first—who tried to divert him but was unarmed and died immediately. Voldemort then targeted Lily, who died attempting to protect Harry. Her sacrifice blocked the Killing Curse on Harry, and her love formed a barrier that rescued him. When Voldemort cast the curse on Harry, it reversed, eliminating Voldemort himself and leaving him vulnerable, without a bodily shape.

Voldemort had endured death through the five Horcruxes he created—his diary, Gaunt's ring, Slytherin's locket, Hufflepuff's cup, and Ravenclaw's diadem. Later, Harry also became one when a piece of Voldemort's unstable soul latched onto him, granting him some of Voldemort's abilities, such as speaking Parseltongue. This event made Harry the only person to survive the Killing Curse, earning him the title of "Boy Who Lived." The curse left a lightning-bolt scar on his forehead—marking him as Voldemort's identical. This scar would serve as both a hex and a gift, as it created a telepathic connection between Harry and Voldemort, permitting them to feel each other's thoughts.

Rubeus Hagrid rescued Harry from the house, which was partially demolished by Voldemort's failed killing curse. Dumbledore expressly ordered him to take Lyra to Remus, who became her adoptive father, and to take Harry to his aunt and uncle.

Lyra was kept hidden from her brother Harry and was disguised under the Fidelius Charm cast by Dumbledore to rescue her from Voldemort.

Life with Remus

Lyra grew up alongside her adoptive father, Remus. Her childhood was marked by deprivation, moving frequently from one rundown Muggle cottage to another because of the stigma surrounding Remus's lycanthropy. Despite the problems, her childhood was filled with love, old books, hot tea, and Remus introducing her to magic at home. She excelled academically and demonstrated a deep love for learning.

To defend her from Death Eaters and Ministry scrutiny, Remus offers her his surname (Lupin) and informs her she is his daughter from his one-time ex-girlfriend, who was slaughtered, and he bore her in to raise.

As the years passed, Lyra's magical abilities began to manifest, leading to a few odd happenings that Remus did his best to clarify away.

Discovery of her mystical abilities

It wasn't until a few days after receiving her Hogwarts acceptance letter that the truth was finally revealed to Lyra. Her adoptive father sat her down and explained the reason for her hidden magical abilities, but did not tell her about her true parentage becuase fearing that Voldemort and the Ministry would find out that Lyra is Harry's missing twin and she could be a target for them, especially Voldemort. Shocked, Lyra struggled to come to terms with the revelation. The world she had known, the identity she had built for herself, all seemed to crumble around her. But amidst the chaos of her emotions, there was a spark of determination. Lyra refused to let this newfound truth define her future.

Hogwarts years (1991–1997)

First Year

Aboard the Hogwarts Express

On September 1, 1991, Lyra confidently arrived at King’s Cross Station with her adoptive father, Remus Lupin. He helped her wheel her belongings to Platform Nine and Three-Quarters while Ethan walked ahead, eager to get to the train.

Lyra watched closely as Remus magically passed through the barrier between Platforms Nine and Ten. Without any hesitation, she ran through the barrier herself and emerged on the platform, her eyes instantly locking onto the Hogwarts Express. With most compartments already full, she maneuvered her things toward the end of the train, where Remus efficiently helped her get everything aboard.

As soon as they boarded, the train departed, and Lyra asked if she could sit with Harry, who welcomed her. They introduced themselves using only their first names. Ron soon approached and asked to sit with them, and Harry agreed. Curiosity sparked as Ron asked about Harry’s scar; in turn, Harry wanted to know if Ron’s entire family were wizards, which they were, with the exception of his mother’s second cousin, who worked as an accountant. When the trolley witch arrived around half-past twelve, Harry took the initiative to buy some treats from the cart and generously shared them with Ron.

Neville Longbottom then came by, frantically searching for his lost toad, Trevor. While Ron attempted a spell to change his rat, Scabbers, a determined girl named Hermione Granger appeared, trying to help search for Trevor. After Ron’s spell floundered, Hermione introduced herself and, upon realizing Harry’s identity, mentioned that he was featured in several books on magical history. As they discussed which house they might be sorted into, their conversation was interrupted by Draco Malfoy, Vincent Crabbe, and Gregory Goyle. Despite Draco’s attempts to win them over, Harry firmly refused to shake his hand after Draco insulted Ron and his family. Goyle then tried to snatch some of their Chocolate Frog Cards, but Scabbers bit his finger, successfully driving the bullies off. Ron explained that the Malfoy family supported Voldemort, but they later tried to claim they had been bewitched, a statement Ron’s father didn’t believe.

Upon their arrival, Hagrid efficiently gathered all the first years and led them down to the edge of the Great Lake. In groups of no more than four, they confidently boarded a fleet of small boats and sailed across the lake to an underground harbor. Hagrid reminded Neville not to forget his toad as he guided them up a passageway toward the castle gates.

The Sorting Tradition

The new students were greeted at the castle door by Professor Minerva McGonagall, who confidently explained the four houses of Hogwarts: Gryffindor, Hufflepuff, Ravenclaw, and Slytherin, along with the rules governing the House Cup. McGonagall then led the first years into a small room off the Entrance Hall, instructing them to wait for her return.

When she reappeared, they entered the Great Hall, where the rest of the students awaited them, along with the remarkable, shabby wizard's hat perched on a small stool.

When her name was called, Lyra approached the Sorting Hat with determination. As it settled onto her head, she experienced a torrent of thoughts and emotions. “Ah, a curious mind, brimming with ambition and intelligence,” the Hat declared. “Gryffindor is the perfect fit for you.” With a surge of pride, Lyra heard the Hat announce her house and confidently joined the raucous Gryffindor table, finally feeling a true sense of belonging.

Meeting Her Dormmates

After the Sorting Ceremony, Lyra confidently directed her new housemates to the Gryffindor common room, where entry demanded answering the Fat Lady's mystery. The inquiry, "Which came first, the phoenix or the flame?" was asked by many first-years, but with the Gryffindor prefect Percy Weasley's direction, they quickly supplied the correct answer and acquired admission.

Upon joining the common room, Lyra was immediately intrigued by its magnificence; it was immense and glowing, featuring a slim, multi-paned window. The moment they stepped inside, Lyra felt a strong sense of belonging taking hold.

When they arrived at the dormitory, Lyra and Hermione found their names on the door alongside Lavender Brown and Parvati Patil. A thrill of excitement swelled through her as she entered the room. The girls presented themselves, and it became obvious that they shared many attractions. Lyra proudly expressed her love for reading, writing, and photography, kindling interesting conversations about their desires.

As the girls settled into their new quarters, they eagerly communicated stories and interests. Hermione highlighted her passion for reading, while Lavender confidently showed her talent for Divination and fashion. Lyra realized the immediate bond forming with her dormmates as they lively discussed their aspirations and goals.

With a spectacular view of the lake from their window, they savored the beauty of Hogwarts and imagined the stimulating adventures that awaited them in the future years. The strong connection among the girls was undeniable, fueling Lyra's confidence for the year ahead.

First-years' lessons

In the Transfiguration classroom, Lyra sat confidently with her friends, determined to absorb every word from Professor McGonagall. The lesson proved to be both challenging and exhilarating as they tackled the fundamentals of Transfiguration. Lyra felt a strong attraction to the idea of transforming objects and was resolute in her pursuit to master this magical art. After class, her enthusiasm surged as she and her friends actively exchanged their thoughts on the lesson, eager to practice their new skills.

The day progressed to Charms class, where they learned the Levitation Charm, Wingardium Leviosa. Although Lyra faced some initial challenges, she quickly gained control and successfully made her feather float gracefully, earning enthusiastic applause from her classmates. The bond among the girls strengthened as they shared tips and celebrated each other's successes. By the end of her first day, Lyra felt a powerful sense of belonging. She was on an incredible journey of friendship and magical discovery at Hogwarts. The laughter, learning, and unwavering support from her dormmates reinforced her commitment to fully embrace her new life in the wizarding world.

Hallowe'en

On Halloween, after Potions class, Lyra spotted Harry, Ron, Neville, and Seamus ahead. Eager to join her friends, she quickened her pace, and a smile sprinkled across her face as she came up to them. Harry was perkily telling them about their contemporary Charms class, where they had been learning the Levitation Charm. However, the moment took a quick turn when Ron made a mindless remark about Hermione, imitating her unkindly. Displeasure flickered across Lyra's face as she stood her ground and firmly scolded Ron for his insensitivity.

Deciding to support her friend, Lyra argued, “Everyone has their potencies and liabilities, including Hermione.” After making her point, she set off in search of Hermione, fully intent on offering her assistance. Despite her efforts, the crowded courtyard prevented her from catching up to Hermione, which left her feeling uneasy. She made a cognitive note to check on Hermione later.

As Lyra sat at the Gryffindor table, her mind was laser-focused on her concern for Hermione, who was notably missing. While her friends entertained themselves in joyful discussion, Lyra pushed her food around her plate with outrage, unable to shake her worry for Hermione's well-being. Halfway through the dinner, Quirrell erupted into announcing that there was a twelve-foot Mountain Troll in the dungeons, before fainting on the spot. The prefects led the students back to their dormitories, but Lyra discovered that Hermione was unaware of the troll and took it upon herself to help rescue her. 

Separating from the group, she and Katie joined Harry and Ron in their critical search for Hermione. Their search led them to the girls' lavatory, where they discovered Hermione facing the troll. In an act of courage, Lyra distracted the troll, letting Harry and Katie attach their wand to its beak. Ron took the opportunity to strike the troll out by levitating its own club and hitting it in the head. Lyra then ran to check on Hermione, relief soaking over her when she was assured that Hermione was uninjured.

Drawn by the mess, the professors came to find Lyra, Katie, Harry, Ron, and Hermione wrapped in dust, with the lavatory in confusion. Professor McGonagall, the charge of Gryffindor, rebuked them for ignoring protocol and placing themselves in serious jeopardy. To everyone’s amazement, Hermione quickly claimed blame, stating that she had reached out looking for the troll because she assumed she could endure it. She stated that Lyra, Katie, Harry, and Ron were just looking for her, and announced that she would most presumably be dead if they hadn't come to her saving. The five of them commiserated over their difficult adventure and congealed their friendship from that moment on.

Quidditch

As the Quidditch season kicked off, Lyra confidently took her place in the Gryffindor stands, surrounded by enthusiastic students ready to witness the highly anticipated match against Slytherin. As Harry and the rest of the Gryffindor team strode toward the starting gate, her heart raced with excitement and determination. The atmosphere buzzed with energy, enhanced by Lee Jordan's lively commentary and the passionate cheers of the crowd. Lycra cheered enthusiastically alongside her friends, swelling with pride for her twin brother as he soared into the sky on his broomstick.

Throughout the match, Lyra's emotions fluctuated between exhilaration and alarm. She watched proudly as Gryffindor scored the first points, celebrating jubilantly with her fellow students. However, when Slytherin resorted to dirty tactics and knocked Oliver Wood out of the game, her exhilaration turned to dread. As Slytherin scored, she felt a growing worry when she noticed Harry's broomstick behaving erratically. With determination etched on her face, she rallied her friends, voicing her concern for Harry and insisting they take action.

Without hesitation, Lyra charged off to confront Snape. Meanwhile, Hermione, filled with equal parts anxiety and hope, focused through her binoculars, her heart racing as she witnessed Harry's struggle. Just when the situation seemed most dire, Lyra set Snape's cloak alight, creating a diversion that enabled Harry to regain control of his broom. When he caught the Golden Snitch, the crowd erupted in thunderous cheers, and Lyra felt a wave of pride for her friend wash over her. As Gryffindor celebrated their hard-earned victory, Lyra joined in the jubilant chants, fully embracing the moment and the strong bond she shared with Harry, still unaware that he was her twin.

After the match, Hagrid took the four of them back to his hut, where Lyra, Ron, and Hermione recounted what had transpired on the other side of the stands and how Snape was cursing his broomstick. Hagrid, however, was skeptical, questioning why Snape would want to harm Harry. Harry confidently told Hagrid about Snape’s injury from the three-headed dog in the corridor on the third floor. Hagrid, taken aback by their insight, inadvertently revealed that the dog belonged to him, asserting that what the dog was guarding was a secret known only to Albus Dumbledore and a man named Nicolas Flamel.

Christmas season

Lyra: "Thank you so much for hosting me, Hermione. Your home is completely unexpected!"

Hermione: "I'm delighted you could join us! We have an impressive lineup of activities prepared for the holidays that you won't want to forget!"

— Lyra and Hermione

On the Hogwarts Express, Lyra and Hermione confidently claimed their spot in a compartment, their breaths visible in the chilly air. When Lyra introduced her adoptive father, Remus Lupin, to Hermione, their bond strengthened as Remus proudly highlighted Lyra's gentle nature. Their conversations flowed effortlessly, filled with laughter and shared stories, creating a warm and inviting atmosphere where everyone felt they belonged.

On Christmas Day, Lyra sprang out of bed, ready to fully embrace the festivities. As the family gathered around the beautifully adorned tree, her heart swelled with joy while she tore into thoughtfully wrapped gifts. The room buzzed with warmth, laughter, and love, uniting them in the spirit of the holidays. Lyra’s gratitude for her family and friends filled the air, ensuring the day would be etched in her memory.

When she arrived at the Granger household, Lyra was enveloped by the loving energy of Hermione's family. They admired the stunning Christmas tree and eagerly exchanged stories about her school adventures. Lyra felt empowered by her connection with Hermione's family, appreciating their kindness and hospitality. Their laughter echoed throughout the room, solidifying that this holiday season would be truly unforgettable. She received a special journal from Hermione, a thoughtful gift that she greatly valued.

Lyra and Hermione thrived in each other's company as they shared stories and laughter, fortifying their friendship. Their days overflowed with warmth, creativity, and new traditions that celebrated the joy of the season together. Lyra recognized and embraced the importance of her connections with Hermione and the Granger family, affirming the vital role of friendship during this festive time of year.

Detention

Recognizing the depth of knowledge that Lyra, Harry, Ron, and Hermione had about the Stone after their meeting in the library, Rubeus Hagrid insisted they meet him in his hut later. The trio, minus Lyra—who was diligently researching in the Hogwarts library—arrived at the hut. While Hagrid was initially reluctant to answer their questions, Hermione expertly drew information from him about the various protections guarding the Stone: Fluffy, the three-headed dog, was Hagrid's, alongside enchantments from Professors Sprout, Flitwick, McGonagall, Quirrell, and Snape. As the heat became stifling, Harry requested that Hagrid open a window, but Hagrid refused, citing the dragon egg he had in the fire. Unfortunately, Draco Malfoy stumbled upon the dragon and seized the opportunity to get revenge by attempting to expose the trio for possessing an illegal creature. Malfoy clearly sought to inform McGonagall about their activities.

The following morning, during lunch in the Great Hall, Lyra approached Harry, Ron, and Hermione with a mix of curiosity and concern after hearing about their detention for being out past curfew. Upon learning that Draco Malfoy faced the same punishment, a smirk spread across her face. She felt a powerful sense of satisfaction knowing that Malfoy’s actions had backfired. As they gathered together, discussing the challenges ahead, Lyra firmly sensed the camaraderie among her friends. Their bond shone through as they reassured one another and expressed an unwavering commitment to support each other through thick and thin.

That evening, after hearing the details of Harry and his friends' difficult meeting in the Forbidden Forest, Lyra sensed a ripple of concern. She was genuinely concerned for Harry's safety after reading his letter describing the ominous sight he had encountered. The seriousness of Harry's threat weighed heavily on her heart, and despite the comfortable atmosphere of her dorm, she denied herself the comfort of dismissing her anxieties. After finishing Harry's letter, she decisively slipped out of bed and approached the window overlooking the grounds of Hogwarts, her mind racing with thoughts of the lurking dangers in the shadows of the Forbidden Forest and the unbreakable bond she shared with her friend.

Quirrell's actual countenance

While speaking to Harry, Ron and Hermione after completing their exams, Harry discovered the strange coincidence that had happened: Hagrid wanted a dragon more than anything else, only to meet a stranger who had one to give him. They ran down to ask Hagrid more about the man who gave him Norbert, only to find out that the stranger never lowered his hood, something of a fashion in the Hog's Head. Hagrid explained that he could not remember much, as the man kept buying him drinks, but said that he thought they talked about Hogwarts and the kinds of creatures Hagrid looks after there.

Concentrating on remembering what had happened that evening, Hagrid accidentally let slip that Fluffy fell asleep when music was played. Now convinced that Snape had all the information he needed to get past Fluffy, Lyra, Harry, Ron, and Hermione decided to go see Professor Dumbledore and tell him their apprehensions. While walking across the Entrance Hall, they were stopped by Professor McGonagall, and decided to tell her what they had found out. She urged that no one could steal the Stone, and told them that Dumbledore was in London for the day.

As the three set off that night to stop Snape, they were stopped themselves by Neville, who believed that they were sneaking out without reason again, and was anxious that they would lose Gryffindor even more points. Desperate as they were for time, Hermione paralysed Neville. Meanwhile, waiting in the corridor, Lyra glanced around, and just as she prepared to walk away, she was nearly captured by Professor Snape, who was patrolling the grounds. Lyra quickly weaved behind a nearby wall, holding her breath as Snape glanced around. Fortunately, Snape eventually flew upstairs, permitting Lyra to escape concealed. Reunited with Harry, Ron and Hermione, Lyra slipped under the invisibility cloak, and they made their way through the hallways of Hogwarts.

When they arrived at the third-floor corridor, it was to find Fluffy awake, with a harp by his feet. Remembering what Hagrid told them, Harry began to blow into the wooden flute Hagrid gave him for Christmas. From the first notes, Fluffy's eyes began to droop, and he quickly fell asleep. Jumping through the trapdoor, they found themselves in Professor Sprout's room, filled with Devil's Snare, which almost smothered them.

The next room, Professor Flitwick's, held a bunch of flying keys and some broomsticks. Harry found the correct key, caught it, and unlocked the next door with it. The next room was Professor McGonagall's, and it had a large chessboard for a game of Wizard's Chess, which Ron won at the cost of sacrificing himself. Lyra, Harry, and Hermione continued to the next room (leaving an unconscious Ron where they could return for him) to find an unconscious troll: Professor Quirrell's room. Lastly, they entered Professor Snape's room and found seven potions in bottles, along with a roll of paper giving clues on which one to drink to continue: a logic riddle. Lyra and Hermione solved the mystery, and at Harry's encouragement, drank the potion that allowed Hermione to head back so that she could get Ron out, while Harry and Lyra drank the potion to go forward to the final room.

Once inside the room, Lyra and Harry's attention was drawn to two things: the Mirror of Erised and Quirrell. Quirrell bound Amelia and Harry before explaining that the Mirror was the key to finding the Stone. Desperate to distract him from the Mirror, they questioned Quirrell, who revealed that he was serving Lord Voldemort, and although Snape hated Harry (because Snape allegedly loathed Harry's father in their time at school), he never wanted him dead. Unable to locate the Stone, Quirrell asked Voldemort for help; much to Harry's surprise, a voice which seemed to issue from Quirrell himself said: "to use the children".

Glancing in the mirror, Lyra saw a beaming woman who didn’t know who she was, alongside a man and her friend Harry. While Lyra wondered who the lady and gentleman were, Harry saw his reflection pull the Stone from its pocket and put it back. He then touched the real Stone and slipped it into his own pocket. He told Quirrell that he had seen himself winning the House Cup, but Voldemort, an accomplished Legilimens, told Quirrell that Harry was lying and demanded that Quirrell let him speak "to the children". Quirrell unwrapped his turban and turned away from Lyra and Harry. Voldemort’s face, protruding from the back of Quirrell's head, demanded that Harry hand over the Stone. Harry refused, and Quirrell grabbed Lyra and Harry, making Harry's scar burn with pain. But when Quirrell's hands touched Harry's skin, they glowed, forcing Quirrell to release them both. Realising that contact caused Quirrell pain, Harry grabbed his arm and held on until he blacked out. Shortly afterwards, Lyra also passed out, and Snape, McGonagall, and Dumbledore discovered them.

Lyra awoke in the hospital wing, her head covered and her chin stitched, with Harry lying in the bed next to her, his arm also covered. She reached out, and their shared anxiety for each other fast turned to comfort when they were reunited. Albus Dumbledore and Severus Snape soon arrived, and Albus consoled them, stating that Quirrell did not succeed in obtaining the Stone, and that the Stone had, in fact, been eliminated. Dumbledore then explained that the reason why Quirrell could not touch him was that Harry's mom had died to defend him, granting a shield against Voldemort. Meanwhile, Snape was sitting by Lyra's bedside with an anxious gaze and holding her hand.

At the End-of-Term Feast, after apparently hailing Slytherin on beating the House Cup, Dumbledore awarded Ron, Katie and Hermione fifty points, Lyra and Harry sixty points, and Neville ten, which authorized Gryffindor to win the cup.
