— Seth, on life at Hogwarts.

Seth James Black is a half-blood wizard, born on the 12th December 1980 to Sirius Black and a muggle woman called Arden Cartwright and the half brother of Diana Black. He was born in the town of Newbury in Berkshire, England, and grew up there living mostly as if he were a normal muggle boy. He attended Hogwarts from 1992 to 1999 and was sorted into Ravenclaw house, to the surprise of a lot of people (but no suprise to those who knew him best). He proved himself a talented student in the subjects he found himself particularly drawn to, despite the disadvantage of not growing up in a magical home. However, he did less well in most other subjects, finding it hard to concentrate without an interest in the subject matter.

His best subjects at school were transfiguration and potions, while he did well at potions his enjoyment of it was initially marred by Professor Snape, who treated Seth as if he was a clone of his father (presumably due to the strong family resemblance). His ability to enjoy the lessons increased with Professor Slughorn taking over the role again, as he didn't have any vendetta against him. Seth got a pet tabby cat he named Merric at Diagon Alley in 1992 as he bought his supplies for school, and kept it throughout his years at school.

When Seth was only a baby, his father was falsely accused of murder and sent to Azkaban, while Seth still had magical reletives who told him what had happened, and other male role-models, his father's abcence deeply impacted on his life. During his younger life he started showing magical characteristics somewhat later than his wider family, leading his magical relatives to wonder if he would be a squib. A few days after his seventh birthday, however, he made a decent-sized Christmas tree hover, in front of several muggles. Tragedy struck again for Seth when his mother died when he was eight, leaving him in the care of his uncle, Phillip Cartwright, a muggle and languages teacher.

Because his uncle taught MFL (Modern Foreign Languages) at the local high school, though he obvioulsy attended Hogwarts instead, he learnt passable French as well as some German while in his Uncle Phil's care. Having shown an interest in doing so. This meant that professors would often use him as a messenger to Beauxbatons students while the triwizard tournament was on, which he says improved his skill, if only a bit.

In his fourth year he was a member of Dumbledore's Army, wanting to actually learn some true defence magic that year and wanting to push back against Professor Umbridge. During the Second Wizarding War, Seth was forced to attend a hellish version of Hogwarts. He rejoined Neville Longbottom's DA, feeling all the more neccesity in fighting some of the staff, such as the Carrow siblings. Similarly to a lot of his classmates he was severely punished for disobaying teachers when they tried to get them to test unforgivable curses on first years, among other atrocities. He participated in the Battle of Hogwarts.

In later life Seth went on to be one of the front-runners of a popular wizarding rock band Auberon, as the lead guitar and backing vocalist. He was known to have written the lyrics for a lot of the songs. The band was somewhat of a project of his and the lead singer, Marina Yarrow. They're known to have supported the Weird Sisters at least once in their earlier years, to get themselves "out there". Due to his success, as of 2004 he features as a silver Chocolate Frog Card, and (less positively) in several gossip pieces penned by Rita Skeeter over the years of Auberon's activity.

Seth is a member of the Black Family.


Early LifeEdit

Seth James Black is a half-blood wizard, born on the 12th December 1980 to Sirius Black and a muggle woman called Arden Cartwright and the half sister of Diana Black. Seth came about quite accidentally, neither his mother nor father having planned to have a child; however, when she descovered her condition, Arden's decision to have him and raise him herself was quick. He was born in the town of Newbury in Berkshire, England, and grew up there living mostly as if he were a normal muggle boy. When Seth was only a baby, his father was falsely accused of murder and sent to Azkaban. While it was true that Seth had some magical relatives who told him what had happened, and other male role-models, his father's absence deeply impacted on his life. The reason why he was absent becoming the cause of his being avoided, and sometimes bullied, at school. This was exacerbated by the fact everyone in his life seemed to believe, and instill in him, that his father was an innocent man. Unjustly thrown in Azkaban without trial.

It wasn't that he didn't know of the magical world at all, however, as a child his mother remained in contact with his father's closest family who were not obsessed with blood purity, Sirius' cousin Andromeda Tonks. Andromeda also looked after Seth's half-sister, Diana, whose mother sadly didn't survive the first wizarding war. The visits gave the half-siblings the chance to bond, and Seth the chance to get to know the wizarding world, so he would not have to be flung into it when he got his Hogwarts letter. However, after his visits to his paternal family (the good ones, anyway), he would always return back home to a relatively normal life in Newbury.

As Seth grew ever older without showing an obvious sign of magic, his magical family started to wonder things. While they would accept him either way, undoubtedly, they started to consider the possibility that he was a squib; that despite his magical father he himself would be unable to channel magic at all. It wasn't common, but it was a possibility. It was why magical children were not accepted into Hogwarts until they actually showed their magical ablility. They were concerned about this because they knew that if Seth knew about all this magic in the world, and couldn't be a part of it, it would likely be hard for him.

Their worries were eventually dismissed soon after Seth turned seven, however. One time near Christmas, when a fairly large tree at a Christmas market began to topple over, its stand having broken. Instinctively, and without thinking about it, Seth made the tree hover in mid air for a few seconds, allowing himself to move out of the way. The tree itself wouldn't have harmed him, but a reflex kicked in. Since this was in the middle of a Christmas market, naturally tons of muggles witnessed the tree hovering in mid air for a good ten seconds. This meant a partularly irritated obliviator had to be called in to deal with the issue. At some point during this year Seth accidentally made Diana's hair turn green. He also was given his guitar, and begun to learn to play it.

Around this time in Seth's life, his mother had already started to get more noticeably ill. While he was worried about her, he just told himself that it was nothing, that she would feel better soon. He convinced himself people always got better when they got ill. Unfortunately for Seth, his wishful thinking would ultimately prove wrong. Arden eventually died from a form of Lukemia when Seth was eight years old. This left Seth in the care of his uncle, Phillip Cartwright, a muggle modern languages teacher also loving in Newbury. The young man was close with his uncle, who did a lot to comfort him as he came to terms with his mother's death, but it made the shock and grief no less profound.

Hogwarts YearsEdit

Because Seth did eventually show signs of magical ability, he was accepted Hogwarts from 1992 to 1999. He recieved his Hogwarts letter adressed to his room, to his suprise, and it was he and his uncle that was expected to collect the supplies he needed, with the help of his family members in the wizarding if needed.

First YearEdit

His first year was 1992, the year where the Chamber of Secrets was opened for the second time, an unfortunate first introduction to the school for anyone. Though he had no way of knowing about that before he attended. In the weeks leading up to getting on the train and going to Hogwarts Seth was overcome with excitement about the coming school year. His family had all told him amazing things about the place. He was fairly sure he knew everything about it at this point, from the Hogwarts Express all the way down to the Giant Squid that resided on the grounds, and he couldn't wait to see it all in person.

But before he could get on the train to see it all, he had to buy his supplies from Diagon Alley. He and his uncle went through the list of all the supplies he needed, like his uniform and books with the help of his aunt Andromeda. When it got to the point where he saw that he could get a range of pets, Seth persistently nagged his uncle to allow him to get one. When Phil relented, Seth got a pet tabby, which he named Merric. His uncle did manage to persuade him out of getting a lot of things in the Gryffindor house colours, and though he agreed, Seth didn't really understand why, he was sure that was the house he'd been in. It was his sister and his father's house.

However, things didn't go as Seth expected from then on. From the moment he got on the train at platform 9¾ he begun to notice strange looks directed at him. People talking and then stopping when they noticed he was there. He instantly knew what they must be talking about; they were talking about his father. By the time Seth eventually arrived at the school after the train journey he'd begun to feel disillusioned with it all. He knew now, people already hated him, before they'd even met him.

As if he hadn't had enough surprises, when it came time for Seth's sorting, he was sorted into Ravenclaw house. This came as a surprise to a lot of people, those who knew who he actually was anyway, as they'd been expecting Gryffindor, or Slytherin, no one put the people who were actually close to Seth saw this coming even remotely. Seth was disappointed, he'd wanted to be in the same house as his sister, now he was in a completely different one and he had no one there he could talk to, he'd never been outgoing; there was no way he was making friends easily in a school full of people who thought his father was a mass murderer.

It was almost a month into the year before Seth befriended Marina Yarrow. Because she was muggle-born, she wans't really in-the-loop about who Seth's father was, and what he had supposedly done. While he did explain it to her, more or less, she didn't push him away like evryone else had; she trusted that, even if he was wrong and his father was guilty, he obviously wasn't like him. Marina told him it wasn't his fault whatever his father did or didn't do. After this, Seth begun to build some more confidence about himself. The two bonded over their shared love of rock music.

As the year went on, weird and frightening things began to happen. The word spread around the students that the Chamber of Secrets had been opened, as muggle-borns began to be found petrified. The result was an air of terror amongst most of the students, but especially muggle-borns, like Marina. Marina refused to walk the halls without Seth or somone else with her, and Seth was glad to help, though he wasn't exactly feeling brave about things himself. Hogwarts was definitely not the wonderland he'd expected it to be, that was for sure.

Despite all of the horror, it was hard for both young magic users to deny the positive sides to Hogwarts, they couldn't dwell on the possible danger all year, after all. It would drive them insane. Instead theyspent their time, mainly in the Ravenclaw Common Room, due to the curfew, immersing themselves in the world of magic. The two youngsters descovered they both had a passion for rock music, and began fanticising about creating their own group (Seth could play the guitar, after all). Unfortunately, they weren't sure where they would even find the other members.

From his first lesson Seth started to show his natural skill in potions. Unfortunately, however, due both to his overly favourable attitude to Slytherin students and distain toward those from other houses and the fact that Seth was the son of Sirius Black, the potions master Severus Snape treated Seth with notable contempt. Much similarly to how he had treated Harry Potter, and for much the same reason. The situation wasn't aided by Seth's resemblance to his father, with only his light brown hair and attitude to distinguish him from his father at his age. Of course, Seth had no idea why Snape disliked him particularly of course, he only knew it wasn't fair.

Seth's other main magical skill was in transfiguration, where Seth had a much better time showing his aptitude, given that Professor McGonagall didn't show any favouritism she may have had to her house's students, and didn't seem to hate him. She initially seemed particularly to keep her eye on him, as if she expected him to play some kind of prank at any moment, but soon softened as he proved dedicated to actually learning. Given the rapport he developed with her as a good student, he even tried, on one occasion, to ask her why it might be that Snape hated him. She only turned pale, paused for what felt like hours, and said something along the lines of "I'm sure you're just imagining things". Even at the time, Seth thought that McGonagall didn't think that he was imagining things.

Second YearEdit

“Yeah, and tell me who deserves that without a trial. No one deserves to be anywhere near those things either way but they never gave him one. Did you hear that part? They just said he did it, tossed him in with those things and threw away the key. He was your dad's best friend and they didn't even question it. Why would he heel turn like that? What possible motive would he have? He was good to my mother, she always said that much, why would he be good to a muggle if he hated them? Why would he look forward to seeing his half-blood son if he thought I was scum? Why would he name me after your dad, Seth James Black, if he was going to betray him a few months later? Maybe that all happened, but I doubt it, and until I have evidence I'm wrong why on earth wouldn't I?”
— Seth's angry reponse Harry Potter's confrintation of him.

Seth was noticably less hyped for his second year at Hogwarts as it was. He had enjoyed his time there and was still keeping in touch with Marina Yarrow, his close friend from his first year. However there were some things that had made it less of the positive experience he'd expected, what with the chamber of secrets being opened and the potions teacher (who taught the subject he was interested in most) despising him. He grew even more apprehensive, however, was the fact that he had heard that his father Sirius Black had escaped from Azkaban over the summer. While Seth believed wholeheartedly that his father was innocent, he was aware that virtually no one else in the wizarding world did. Everyone knew who Seth's father was, he had no idea how people were going to treat him once he got back, but he didn't suspect it would be well.

One of the first things he had to do was explain to Marina that his father had escaped from a prison that was supposed to be impossible to escape. The news was everywhere, but Seth had no idea how much people at the school were going to take things out on him (or her as well, for her association to Seth). In theory she'd understood Seth's insistence that his father was innocent, but he wasn't sure how she'd be in practise now that the issue was really in the public eye. If it wasn't for Diana, Seth wouldn't know if he'd have anyone to talk to.

He was right about his classmates, things were colder than they had been even in his first few weeks last year. He got sour looks in the corridor and no one in the dormitory would talk to him, only mutter from a distance. Everyone except Marina who stood up for him when she could; which was more often than Seth, who couldn't manage to make any kind of reply to the various insults and accusations levied at him, did in his own defence. Unlike his first year, the hostility didn't let up at all. Seth was made a pariah by everyone but Marina, as the fact that Seth believed in his father's innocence was spread around.

Third YearEdit

His third year was a the first year he has mostly fond memories of, the year of the Triwizard Tournament.

Fourth YearEdit

Fifth YearEdit

Second Wizarding WarEdit

Sixth YearEdit


Seventh YearEdit

Later LifeEdit



  • Seth as a name has two origins. One of these is from Σεθ (Seth), the Greek version of Egyptian Swtkh/Sutekh, possibly meaning "pillar" or "dazzle". Also known as Setesh, Suty and Set, Seth was the god of the desert, storms, disorder, violence, foreigners and chaos in Ancient Egypt, and the slayer and mutilator of Osiris. Orisis' son Horus eventually defeats Seth and banishes him into the desert.[1] Another more common intended meaning is "placed" or "appointed" in Hebrew. In the Old Testament Seth is the third named son of Adam and Eve. In England "Seth" started being used after the Protestant Reformation, suggsting this is the more likely origin of the name for Seth Black. [2]
  • James is the English form of a Latin name, Iacomus, which was derived from New Testament Greek name Ιακωβος (Iakobos). All were forms of the Hebrew name Ya'aqov. It's a Biblical name, as it was the name of two of the apostles in the New Testament.[3] In Seth's case, the middle name James was likely chosen by his father in honour of his best friend James Potter.
  • "Black can be considered a colour, and is the result of the absence of, or complete absorption of, light. In Western culture, the colour black has typically been associated with evil, darkness, and witchcraft, but also with prestige and sophistication — appropriate for the rich and House of Black. Black has also been associated with life and prosperity by other cultures. In ancient China, black was the symbol of the element of water, which also corresponds to Slytherin, the Hogwarts house of almost all members of the Black family. In English heraldry, black represents darkness and ignorance; a possible allusion to the prejudice common to members of the House of Black."[4]


  • Due to his uncle Phillip's occupation as a MFL teacher, Seth was able to learn French fairly well.
    • A few of Auberon's songs are written partially in French and there is both an album and a track on that album titled "Jamais Pur", a play on his paternal family's motto, "toujours pur". While the original motto means "always pure", the spoofed version means "never pure".
  • He started off learning to be an animagi because his father had, but put it to use during the year where the Death Eaters were running Hogwarts, as no one was aware the fluffy black cat was him.
