- "I'll never apologise to you losers and Mudbloods! I'm Merula Snyde! Fourth generation Slytherin! The greatest witch at Hogwarts! I do what I want when I want! I run this school!"
- —Merula Snyde's opinion of herself[src]
Merula Snyde (born c. 1973) was a witch who began attending Hogwarts School of Witchcraft and Wizardry in 1984 and was sorted into Slytherin. Merula acts as the first major antagonist Jacob's sibling encounters during their time in Hogwarts and remains a persistent rival to them throughout the years.
Hogwarts years (1984-1991)
Merula began attending Hogwarts School of Witchcraft and Wizardry in 1984. On 1 September, 1984, during the journey on the Hogwarts Express she tormented Ben Copper the entire time, by threatening him and calling him a "Mudblood."
Once they arrived at the school, Merula and the rest of the first years were greeted at the Great Hall by the rest of the students and the staff. Professor McGonagall proceeded to provide them with a short explanation of the four Hogwarts Houses — Gryffindor, the brave and chivalrous, Hufflepuff, the kind and diligent, Ravenclaw, the witty and wise, and Slytherin, the cunning and ambitious — voicing her hope that all of the newcomers would make fine additions to the ranks of great witches and wizards that each House had produced in the past. Eventually, Merula was sorted into Slytherin, becoming the fourth generation of her family to be sorted in that house.
As a result of her constant bullying, Ben Copper spent his first days at Hogwarts following Merula around, hoping this would prevent her from sneaking up on him, or give him a chance to run away if she did. One day, before the start of a Potions class in the Dungeons, Merula was bullying Rowan Khanna by forcing them into saying that she was the most powerful witch at Hogwarts. However, Jacob's sibling stood up for Rowan and Merula started teasing them by making fun of Jacob. When Rowan mentioned that Professor Flitwick said Jacob's sibling cast the best Wand-Lighting Charm of any first-year in years, Merula resolved to be nothing but trouble for them and to show that she was more powerful than them.
She then sent Jacob's sibling a fake letter from Professor Snape and locked them in a room full of Devil's Snare, but they were able to escape, thanks to Hagrid's timely intervention. Afterwards, Merula reappears as Rowan and Jacob's Sibling are playing gobstones, and begins to taunt the two. She insinuate that Jacob's quest for the Cursed Vaults led him down a dark path that resulted in him joining Voldemort. Jacob's sibling is presented with an opportunity to retaliate by bringing up Merula's Death Eater heritage and how her parents are in Azkaban in response. Regardless, the argument eventually escalates to Merula challenging Jacob's sibling to a duel and ends with Merula using the Knockback Jinx on Jacob's sibling, as the only spell they know up until that point is the Wand-Lighting Charm.
After receiving training from their prefect, Jacob's sibling finds Merula in the Clocktower Courtyard, bullying Ben Copper by expressing her distaste for Muggle-born and half-blood wizards in Hogwarts. Jacob's sibling intervenes to defend Ben and challenges Merula to a duel, which they win. Shocked at Jacob's sibling's mastery over the Disarming Charm, Merula refuses to acknowledge her defeat or apologise for her behaviour, while proclaiming herself to be the greatest witch in Hogwarts and free to do what she wants. Professors Snape and Flitwick approach her from behind during her tirade, much to her surprise and begin to question what happened here. Ultimately, Jacob's sibling is blamed for the duel, regardless whether or not they struck Merula first, and is forced to lose points from their house.Immediately after this, Merula follows Snape and Filch into the fifth-floor corridor, with Jacob's sibling following after her. Together, they spy on Snape and Filch having a conversation about the cursed ice and sealing a room within the corridor to contain it from spreading. Jacob's sibling and Merula briefly discuss the nature of the cursed vaults, before going their separate ways. Jacob's sibling later meets Merula in another potion's class and she asks whether or not they divulged the vault's existence to anyone. Regardless of their answer, Merula will taunt Jacob's sibling and then focus on their lesson for brewing a Herbicide Potion. At the end of class, Jacob's sibling attempts to assist Merula by giving her tips on how to correctly brew the potion, to which Snape awards them with house points, much to Merula's chagrin.
Towards the end of the year, Jacob's sibling, along with Rowan and an optional party member, will investigate the fifth-floor corridor where the cursed ice is supposedly spreading from. Initially, the trio investigate a door leading to a small room where the ice originated from, only to be ambushed by Merula casting the Knockback Jinx on Jacob sibling's and their friends. After declaring that only she can claim the power and treasures of the vault for herself, Merula enters the small room alone, while the trio follow after her. Upon entering the room, they discover Merula partially encased in a block of ice from the waist down and she demands Jacob's sibling to help her. After being freed from the ice and escaping the small room, Merula declares this whole expedition to be a waste of her time and leaves the area. Merula isn't seen again, except briefly in the End-of-Term Feast.
During the 1985–1986 school year, Penny Haywood warned Jacob's sibling that Merula was eager for a rematch after being defeated by them the previous year. During a potions class, Jacob's sibling attempted to reason with Merula, citing that nobody cared about what happened last year. Merula points out that, whenever duelling was mentioned, their duel was often brought up and how strong Jacob's sibling was compared to her. As a result, Jacob's sibling had no choice but to accept Merula's challenge, but was helped by Penny in preparation for their second duel. Jacob's sibling then met with Merula in the Clocktower Courtyard at night, emerging victorious from their duel. Merula was confounded by her second defeat, but stated that, while their duel was concluded, the rivalry between them would never be over.
Merula is next seen in Potions class, asking what Jacob's sibling has been up to. Regardless of their response, Merula will boast about working with someone in order to unlock the secrets of the vault before Jacob's sibling can. Snape then interjects, warning Jacob's sibling of potentially being in dire trouble, which will be discussed once class is over. After class, Snape accuses Jacob's sibling of stealing potion ingredients from his storeroom, as his stolen ingredients were found by their bed's drawer. With a sufficient stat check, Jacob's sibling can pin the blame on Merula, pointing out her previous attempts at sabotaging them, along with being capable of duping another student into planting the ingredients in their room.
Snape promptly asks Merula if what Jacob's sibling says is true, but she denies it, stating that she only wishes to see Jacob's sibling expelled for being a danger to Hogwarts. Snape, however, points out that Merula is an atrocious liar, due to her constantly darting her eyes in multiple directions whenever she lies. As a result, Merula is punished by being forced to maintain Snape's storeroom for the rest of the year for attempting to frame Jacob's sibling.
Merula is last seen in Flying Class, sarcastically asking how their friends are doing after a failed excursion into the Vault of Ice. Jacob's sibling will angrily retort for Merula to not pretend to care for their friends, to which she replies that she does not, but only about the Cursed Vaults themselves. Merula will then claim to know what happened to Jacob, to which his sibling will desperately demand Merula to them what happened to their brother. Merula replies that she will, after flying class was over.
After class, Jacob's sibling immediately asks what Merula knows about Jacob's whereabouts, to which Merula attempts to force them into swearing that any future information they learn about the vaults should be relayed to her. Regardless of the their response, Merula will ominously state that Jacob does not have much time left. After this exchange, Merula is not seen for the rest of the year.
Merula returns in third year, this time with a gang of her own to help her seek out the remaining vaults. Merula introduces them as Ismelda Murk and Barnaby Lee to Jacob's sibling during the lesson on Wideye Potion. The former threatens Jacob's sibling to keep away from Merula this year, while the latter expected them to be taller. Exasperated, Jacob's sibling urges Merula to not start another argument with them, to which Merula agrees, since she plans on focusing her efforts on finding the next cursed vaults, with the help of her new associates.
After their lesson is over, Merula's gang discusses what sort of power the next vault might hold. Ismelda gleefully hopes that it is something that can resurrect the Dark Lord, while Merula taunts Jacob's sibling that it may hold the power to bring back their brother. Jacob's sibling response will prompt Merula and her gang to leave, but not without Barnaby threatening the sibling via a bone-vanishing spell. After a short discussion about why Barnaby is working with Merula, the burly student leaves to follow after Merula.
At some point, Jacob's sibling meets with Tulip Karasu, who tells them that she used to be Merula's only real friend during the first years at Hogwarts, due to taking a liking to her rebellious and free-spirited personality. Together, they made an effort to search for the vaults and they eventually stumbled upon Jacob's old room, where he kept his notes and information he found on the vaults away from prying eyes. Unfortunately, as time went on, Merula and Tulip would have a falling out, due to both girls becoming greedy for power and purposely withholding information from one another. As a result, the two locked Jacob's room with a lock, which was immune to the unlocking charm, that could only be opened with a key each girl had.
Jacob's Sibling and Tulip would later go on to spy on Merula and her cohorts in the Clocktower Courtyard. Merula would loudly proclaim her frustration at finding clues to the next vault, while Ismelda would insist on using the Cruciatus Curse on Jacob's Sibling to torture the information out of him, much to Merula's disgust. Tulip devised a plan with Jacob's sibling in order to acquire the key from Merula, which involved the use of a Jumbo Dungbomb, to scare away Merula's allies so they could confront her alone. After acquiring the Jumbo Dungbomb from Zonko's Joke Shop in Hogsmeade, the pair found Merula and her gang hanging out by the Clocktower Courtyard again, making small-talk. Ismelda claimed she would use the Killing Curse, on the next Gryffindor she saw, to which Merula replied that Ismelda does not know how to cast the spell.
Barnaby chimes in by mentioning how he once killed a bowtruckle by accidentally sitting on one, which confuses Ismelda for having nothing to do with their conversation. In the end, Merula proclaims she hates them both. While they were distracted, Jacob's Sibling hardened the bomb with duro before launching it in-between Merula's gang with the Banishing Charm. Initially confused by the object, Ismelda and Barnaby would quickly retreat once the Jumbo Dungbomb released its foetid payload, while Merula seemingly withstood the stench.
Jacob's Sibling and Tulip reveal themselves to Merula, who had a feeling they were behind this prank. Tulip demands Merula surrenders the key to them, which causes Merula to angrily retort at how Tulip betrayed her to work with Jacob's Sibling instead. Jacob's Sibling and Merula will then duel for the second key, which Merula loses causing her to forgo her key to her rival, but not without uncharacteristically warning Jacob's Sibling to watch out for Tulip potentially backstabbing them.
Merula next confronts Jacob's sibling in the hallway where Jacob's old room resides. She questions what they were doing in the library, to which Jacob's sibling can either admit or lie to her. Merula will response accordingly and threatens to do something far worse to the student when the time comes. True to her word, Merula, along with Ismelda, intercepts Jacob's sibling and friends in the library as they are about to enter the Restricted Section to find the Vault of Fear. Merula chastises Jacob's sibling for seeking the power of the vaults for altruistic reasons and engages with them in another duel. Jacob's sibling emerges victorious from their duel, but Ismelda launches a surprise attack with Everte Statum, which causes Barnaby, now working with Jacob's sibling instead, to take the hit for them.
Barnaby faces off against his former allies in a two versus one duel and manages to defeat Merula and Ismelda off-screen, while Jacob's sibling entered the restricted section to investigate the area for the entrance to the second vault. Barnaby later says that Merula attempted to tell Professor Snape of what had happened in the library, but nothing would come of it due to a lack of proof from her and Ismelda.
At some point during Merula's third year, Rita Skeeter visited Hogwarts in order to hold a contest, in which the winner would be given the opportunity to be on the front page of the Daily Prophet. Naturally, Merula entered to win the competition, but, as usual, came into conflict with Jacob's sibling who was also competing in the contest, only to learn what they could about Jacob's disappearance from Rita. During a potion's class session, Rita forced the pair to, not only compete in creating the better potion, but to also divulge each other's darkest secrets. Merula eagerly admitted that Jacob went mad and nearly destroyed the school in the process, while Jacob's sibling would have the option of telling Rita of Merula's parents being locked away in Azkaban for being Death Eaters, much to Merula's chagrin. Merula was last seen in the Great Hall, as Rita was about to announce the winner of her competition. Rita would later say that, should Merula be the victor, the article would be about Merula's trouble upbringing due to her imprisoned parents, which was something her readers will enjoy reading about.
Merula encounters Jacob's sibling in their first Care of Magical Creatures class. Immediately, she attempts to stir trouble with her rival, first by insulting Charlie Weasley and then taunting Jacob's sibling about the fate of their brother. Jacob's sibling has the option of asking Charlie to talk Merula down on their behalf, prompting the Slytherin witch to storm off. Sometime later, Patricia Rakepick calls a meeting at the Training Grounds between Jacob's sibling and their group of friends, along with Merula and Ismelda to discuss the Sleepwalking Curse currently affecting students this year at Hogwarts.
Rakepick then teaches the group of students the Blasting Curse as a defensive measure against the threats lurking in Hogwarts. Merula mentions she wished she knew this spell during her first duel with Jacob's sibling. Later on, Rakepick tasks her apprentices in duelling each other for combat experience. Merula can be chosen as an opponent by Jacob's sibling for a spar, which she inevitably loses, though not without declaring to her rival that she will never give up until she wins.
Jacob's sibling is able to deduce that the next location of a cursed vault must be within the forbidden forest, where all sleepwalking students have been magically drawn to. Charlie Weasley and Jacob's sibling devise a plan to enter the forest via flying. However, Jacob's sibling does not have a broom of their own, due to their mother forbidding them use for their own safety. As a result, Jacob's sibling has no choice but to borrow a broom from someone else, one of their options include Merula's broom, which she often brags to be superior.
If Merula is chosen, Jacob's sibling will meet her at the Three Broomsticks Inn to discuss borrowing her broom to venture into the forest. After talking over some butterbeer, Merula agrees to let them borrow her broom, as Rakepick ordered Merula to comply with Jacob's sibling in his investigation of the vaults anyway, but not without also hoping they would suffer serious injuries or expulsion as well.
Later on, Tulip invites Jacob's sibling to their brother's old room, but is surprised at Merula also being there. Drawing their wand, Jacob's sibling demands to know why Merula is Jacob's old room, to which Tulip explains Merula has examined the contents of Jacob's room far more than anyone else has, thus asking for her help seemed like a logical option. Jacob's sibling can either agree or disagree with the decision, but either way, all three of them will search the room together for any clues on the location of the next vault. In the end, Jacob's sibling finds what they were looking for.
Afterwards, Jacob's sibling is given the option to take Penny, Tulip or Merula to the forbidden forest. Regardless of their option, Jacob's sibling will encounter Torvus in the grotto and will have no choice but to fight him, while protecting their chosen companion in the process. If Merula if chosen, she will become timid in the presence of the centaur and refuse to help Jacob's sibling. After the fight, Merula will nervously introduce herself to Torvus, while simultaneously being warned by the centaur to not trust Jacob's sibling.
At some point under Rakepick's tutelage, Merula is ordered by her to spy on Jacob's sibling and to demand reports from them.
Merula enters her fifth year, still as an assistant to Madam Rakepick. During one evening at the start of the semester, Rakepick gathers her favourite pupils, which include Bill Weasley, Merula and Jacob's sibling. Rakepick tells her pupils that they are now a team and should be willing to work and help one another in their quest to find the cursed vaults. She then teaches them the Incarcerous spell, and asks Jacob's sibling to demonstrate the spell on Merula, who was initially reluctant at first, but came around after being convinced by Rakepick. For awhile, Jacob's sibling marvels at the utility of the spell after it ties up Merula, before Bill quickly points out that Merula is struggling to breathe, while Rakepick tells Jacob's sibling to undo the ropes to free her, prompting Jacob's sibling to ask if Merula was alright, to which she responded positively.
Sometime later, Merula invites Jacob's sibling and Bill Weasley to the Three Broomsticks in Hogsmeade, to discuss the second red-robed assailant who attacked Jacob's sibling and Ben in the Clocktower Courtyard and as an attempt to build bridges with her rival. Merula, however, considers the attempt to be a failure, as unresolved enmity exists between the pair. Bill suggests that the two take this opportunity to vent their frustrations out on each other to help them overcome their differences. After arguing about the infamous Devil's Snare prank that Merula subjected Jacob's sibling too and Merula's jokes about Jacob being dead, the two are interrupted by Penny who tells them that her little sister, Beatrice Haywood, has gone missing.
Jacob's sibling suggests that they search around the school, while they search the Forbidden Forest, in case Beatrice may have wondered there looking for adventure. Jacob's sibling may choose to take Merula with them, who offers snarky commentary throughout their search for the younger Haywood in the Red Cap's Hole and the acromantula lair. During their excursion into the lair, Jacob's sibling encounters the same acromantula they defeated in year 4. It demands to know why they have entered its abode again and remains uncooperative while being questioned by the duo, prompting Merula to make a grisly threat in what they will do to it if it refuses to assist them. The acromantula attacks the two students in response, but Jacob's sibling is able to defeat and banish the spider with arania exumai once again.
Jacob's sibling decides to return to Hogwarts with Merula, and then meets with Penny in the potions classroom, after Bill informs them that Penny is brewing a mysterious potion to help her find her sister. Unfortunately, the potion fails to perform its intended effect, which was to allow Penny to locate and read Beatrice's mind through a Legilimens-like effect. Despite her failure, Merula quickly rushes into the class to tell Penny that she found Beatrice in the Grand Staircase. Merula leads them to a part of the staircase and tells everyone she found Beatrice trapped in a painting while wandering the school. While everyone ponders on what to do about Beatrice's predicament, Filch abruptly appears to inform Jacob's sibling that they are to carry out their detention in the kitchens with a house-elf named Pitts.
After receiving advice from Badeea Ali and serving detention with Jae Kim, Jacob's sibling meets with Merula at the Three Broomsticks in order to ask for her assistance in freeing Beatrice from the painting. Merula made note of Jacob sibling's unusual chipper attitude, but nonetheless wonders why they need her help. Jacob sibling's response will prompt Merula to stroke her ego over some butterbeer, by admitting she is the best at everything in order for her to cooperate. Once Merula is satisfied, Jacob's sibling explains to her that rescuing Beatrice is the key to finding the next Cursed Vault, as the curses may be linked. Merula tells Jacob's sibling to look for the Marauder's Map, as it may help them in seeking the location of the fourth vault, before the two go their separate ways.
Merula had short and messy dark brown hair, with one area an orange colour, and violet eyes. She had thick furrowed eyebrows. Merula also smelled like cloves, nail polish, and some other elusive scent. Her stockings have a hole around her left kneecap, and she wears black combat boots.
Personality and traits
A strong-willed yet mean-spirited and cruel witch, Merula Snyde is a talented young girl who exemplifies many of Slytherin's traits, such as cunning, determination and ambition, though also the negative stereotypes of Slytherin, such as prizing pure-blood supremacy. Merula is highly rebellious, sadistic, and petty, and is prone to bullying those around her, especially wizards from Muggle or half-blood families. Her greatest trait, however, is her ambition to prove she is the best, which is her primary motivation for seeking out the Cursed Vaults and the major reason for being in constant conflict with Jacob's sibling. Merula's parents being imprisoned in Azkaban may have contributed to this need for attention as well.
Merula's hatred for Jacob's sibling pushes her to go to great lengths to sabotage her rival, by either attempting to get them expelled or badly injured. Indeed, Merula often goes out of her way to seek out Jacob's sibling in classes, either to taunt them about Jacob or to generally be a nuisance. Merula is always eager for a fight with Jacob's sibling and never backs down from a challenge. Despite her aggressive nature, Merula does demonstrate a strong work ethic and can often be seen studying alone in the library and is noted to be a competent student by many of her peers, especially in potions class. Merula has also been described by her classmates as 'not all bad', hinting at a softer side. Another curious quirk to her personality is her irreverence towards the Dark Lord, as she often refers to him as Voldemort, much to everyone's chagrin.
Magical abilities and skills
- Magical Skill: Merula has often been described as a talented witch by her peers and faculty. Indeed, her skills has been personally praised by Severus Snape and Rita Skeeter, despite her boorish personality. Patricia Rakepick took interest in Merula for her skills and took her on as an apprentice during year four, along with a handful of other highly skilled candidates, such as Jacob's sibling and Bill Weasley.
- Dark Arts: Merula shows a keen interest and skill in the dark arts, mostly in utilising jinxes and hexes on her enemies. She was quickly capable of using the Knockback Jinx in her first year to bully her fellow classmates. Merula also claims to be knowledgeable of hexes during Defence Against the Dark Arts class in her fifth year.
- Care of Magical Creatures: Merula appeared to have a general interest in magical creatures, as she decided to enrol into this class as an elective. Throughout the various lessons, Merula will give her opinion on different creatures brought in for lessons, such as regarding kneazles as 'handsome creatures' while being disgusted with murtlaps.
- Potions: Merula appeared to be quite skilled in potions as she was capable of discreetly sabotaging Jacob's sibling's Cure for Boils with Bulbadox powder. Per Professor Snape, she was able to make a "flawless" Cure for Boils right during her first Potions class.
- Duelling: Merula was known to be a fierce and resourceful duelist. Even during her first year, she showed her multiple martial magic abilities.
- Flying: Merula showed an aptitude for flying and is often seen capable of mastering advanced flying techniques. However, Merula is shown having difficulties with raising her broom and sometimes struggles during other flying lesson techniques.
Behind the scenes
- In Harry Potter: Hogwarts Mystery, when Rita Skeeter hosted a small duelling club to see Jacob's sibling's magical prowess, the player got to choose between Merula, Penny Haywood, and William Weasley to be their opponent. Challenging any of them will eventually lead to their defeat; if picking Merula, after she lost, she declared her disinterest in being on Rita's news article anyways.
- In her second year, Merula boasts to Jacob's sibling that she's working with someone on finding the Cursed Vaults. That someone is likely Tulip Karasu, as the two were still working together during their second year and only ended their partnership before their third year.
- As both her parents are in Azkaban, it's currently unknown who takes care of her. If Merula's claims about attending the Quidditch World Cups are true, it's likely she's being raised by a family member.
- Merula owns a broom she considers to be far superior to the brooms provided by Hogwarts during flying class, claims to that the Snyde family vault in Gringotts contains "jeweled shells", and that her mother owned a unicorn a long time ago. Because of these claims, it can be assumed that the Snyde family was quite wealthy in its prime.
- If Jacob's sibling is sorted into Slytherin, Merula will appear in additional side-quests revolving around plotting revenge against Gryffindor for defeating their house in Quidditch.
- During the Year 4 Prefect sidequest, Merula will appear, along with Rowan and Barnaby, as Jacob's sibling's group of friends, where Merula admits to constantly pushing Barnaby into the fountain with the Knockback Jinx.
- Tulip Karasu's boggart appears to be a distorted version of Merula wearing a torn school uniform, runny makeup and glowing violet eyes. The boggart reminds Tulip over how she betrayed Merula and how she will never have any friends, which Tulip later admits is her greatest fear.
- Starting in year five, Merula can be seen to be noticably less antagonistic towards Jacob's sibling. During the Defence against the Dark Arts classes, including the Hex-Deflection class, as well as the Hair-Raising potion class, Merula can be observed having casual, and sometimes even friendly, dialogue with Jacob's sibling. Most notably, in the Hair-Raising potion class, Rowan is seen to say "is it just me, or is Merula being friendlier lately?"
- Hidden within the game's data are unused formal dresses for several characters, such as Penny Haywood and Tulip Karasu. Merula has her own dress, which may be used in an upcoming update.
