Depending on how you look at it, this group—the core group of the Dangerverse—is either an outgrowth of the Marauders (which is also the singular of Pack) or the next inevitable step (it's been theorized that had James and Lily survived, the outcome might have been similar). After Remus and Danger meet, fall in love, rescue Harry from the Dursleys, and Sirius from Azkaban, and move in with Sirius's girlfriend Aletha, the two small family units end up melding into one, the final result being four parents jointly raising four children—said children including the most famous children in wizarding Britain.Over the course of the series, they have endured and suffered more than most people do, but they have only become closer as a result. They spend more time together than they do with anyone else, and whenever there is a problem, they always try to solve it together.Remus Lupin is for all intents and purposes The Leader, despite his canon self being something of a wimp (the Dangerverse has been described as "the only place in Harry Potter fandom where Remus is the alpha male"), and the group was developing a pack mentality even before they actually began referring to themselves as a pack. (The first use of the term is quite early in the story, though, occurring around Chapter 14 of Living with Danger, so the fourteenth chapter out of 215 (!) so far.) The adults see each other as being related in some fashion (Remus and Sirius see each other as brothers, their respective wives think of each other as sisters, and so on), and the kids, or cubs, have been raised as siblings.
Hidden in Plain Sight: Honestly, who'd think to look for the Boy Who Lived, the Boy Who Disappeared, and the most wanted fugitive in wizarding Britain in a little semidetached in the London suburbs? Not the Ministry, that's for certain.
Idiot Ball: "Find the red and find the rat"? Yeah, good job remembering, everyone. Luckily they managed it anyway, belated as it was.
Heterosexual Life-Partners: James, Remus, Sirius and Peter in their Hogwarts years count as this, but he and James were practically brothers, evidenced by how he was James's best man at his wedding. Remus and Sirius definitely become this. Ditto Danger and Aletha.
Parental Substitute: Not that any of the cubs, other than (maybe) Draco, remember having any other parents...
Reasonable Authority Figure: Out of necessity, as the cubs know just how rule-breaking their parents used to be and will bring it up at any and all opportunities. The Pack has instituted what is known as the Hypocrisy Agreement, by which the cubs cannot be punished for anything the Pack-adults get up to themselves.
Remus John Lupin
Alpha male of the Pack, this iteration of Remus is far less of a wimp than his canon version—mostly because he has self-confidence and people around him who are unwilling to let him sink into depression and despair. Though he is planning suicide at the beginning of the story, his life takes a turn for the better when he almost literally runs into Harry Potter in a park in Little Whinging, during which he meets Gertrude "Danger" Granger, Harry's babysitter. After a Mindlink Mates moment which catapults them into a Fourth Date Marriage, they rescue Harry from the Dursleys, break Sirius out of Azkaban, and go into hiding.Interestingly, he goes from being The Smart Guy of the Marauders (or at least the one with common sense) to being The Hero of the Pack, because not only is James Potter unavailable, Sirius is too emotionally damaged from Azkaban to take any greater role. By the time things stabilize, Sirius is perfectly happy in his place as beta, and Remus, much to his bemusement, continues as alpha.Physically, he resembles his canon version, with gray-streaked sandy brown hair and blue eyes, though he shows fewer signs of premature aging than canon!Remus due to a less stressful, or at least happier, home life. His eyes usually show some signs of Danger's brown, thanks to their mental bond; lack of this little quirk is a very bad sign. He is only slightly shorter than Sirius, but slender, though still strong.He is particularly close with Hermione and Draco.Remus was named by the Founders of Hogwarts as an honorary Heir of Gryffindor, and given control over fire. Fitting, considering his Animagus form is a lion.
Animorphism: Doubled, as he is both a werewolf and a lion Animagus.
I Just Want to Have Friends: Named in canon as the reason Remus never called James and Sirius on their wilder stupidities. Subverted in DV as Remus has to keep Sirius under control if they all want to keep living.
Mindlink Mates: He and Danger are connected on a level they don't quite understand themselves, but which has both a mental and a physical component (as in, if they're apart for longer than a day, they start to get sick).
Our Werewolves Are Different: In the Dangerverse, lycanthropy is distinguished by four qualities. A werewolf (1) changes bodily into a wolf at the full moon, (2) loses his/her human mind in the change, (3) is a social outcast because of 1 and 2, and (4) cannot have children. This last is named in-universe as the "mercy" of the originator of lycanthropy (in this version, Rhea Silvia, mother of Romulus and Remus, who was the she-wolf who nursed the twins and who later asked the god Mars, the twins' father, to send down a curse upon her surviving son for murdering his brother).
Papa Wolf: Do not mess with his cubs. He will find you.
Alpha female of the Pack and wife to Remus; without her, the Pack literally could not exist as it does now. She was in many ways the catalyst that brought everything together, and is definitely one of the reasons it continues to work.Her propheticdreams after her parents' murder (which also forced her into the role of parent to her sister Hermione) led her to find and babysit Harry, saving him from his relatives' abuse for at least a few hours a day. She was also the means by which Remus learned the truth about Sirius and Wormtail, and her ability to "tame" his werewolf mind during full moons allows him to avoid some of the debilitating effects of his transformations and consider himself safe to be around children, leading to the Pack lifestyle.Though she began as something of a Mary Sue, her powers have some fairly sharp limits, and she has both a temper and a lingering self-esteem problem. Physically, she strongly resembles an older Hermione, with similar bushy brown hair and brown eyes (although DV!Hermione's eyes are hazel). When her bond with Remus is in effect, her eyes also have some traces of his blue. This not being present is generally considered a bad thing. She is the shortest of the Pack-parents, with both Harry and Draco overtaking her in height by their fifth year.As an honorary Heir of Gryffindor, she was gifted with control over fire, a power she shares with Remus.She is closest with Harry and Hermione.
Mindlink Mates: Very possibly related to the "taming" power she has over Remus, as the "curse" portion of lycanthropy, which shuts out the human mind to allow the wolf to take over, is only calculated to have power over one mind at a time.
Team Mom: Literally, in the cubs' case, and figuratively with the other adults.
Sirius Valentine Black
Beta male of the Pack, Sirius is happier and less damaged than his canon counterpart (the fact that he was in Azkaban for a few months rather than more than a decade and was able to get some kind of psychological help from those around him helped a great deal). A merry prankster and romance-novel writer under the pen name of Valentina Jett (long story), he is also a loving father-figure and arguably the "cool" parent.Physically, he resembles his canon counterpart, with dark hair and Gray Eyes, and is the tallest of the Pack-adults; he keeps himself in excellent shape both for vanity's sake and due to his rejoining the Auror Office around Harry's third year. He pretends to overreact when he finds gray hairs so that Aletha and Danger will have a reason to tease him which is unrelated to any of his actual personality flaws.He is closest with Harry and his daughter Meghan.
Bad Dreams: Has to cope with these after his stint in Azkaban.
Hero with Bad Publicity: Up until his trial and exoneration, most of the wizarding community believed him to be a dangerous and violent mass murderer. The reputation takes years to shake.
Horrible Judge of Character: Twice over. Unbeknownst to anyone else, he had James and Lily make Peter Pettigrew their Secret-Keeper—thinking no one would ever suspect it and that Peter would never betray them. On top of that, Sirius didn't want the Secret-Keeper to be Remus, as he suspected him of being Voldemort's spy.
I Have No Son: His parents disown him and burn his name off the family tree after he runs away. This was, admittedly, probably the reaction he was hoping for.
In the Blood: Subverted. Sirius was disowned from his family for being a "dirty Muggle lover who has no respect for tradition" (read: a decent human being), and ended up in Gryffindor, whereas every member of his close family was in Slytherin. However, he still has some of the arrogance of his family members.
Most Writers Are Writers: Sirius writes romance novels under a pen name. A female pen name. Naturally, Hilarity Ensues. Though, to be fair, it's not like he has anything else to do while the Pack's in hiding. This is something of a meta-example, in that lines quoted by Sirius as his own work are often from other stories of Anne's.
Papa Wolf: Don't threaten his cubs. You won't like him if you threaten his cubs.
Parental Substitute: Except to Meghan, who refers to him as "Dadfoot" (probably inevitable, as his name to the other cubs was always "Padfoot", right back to baby Harry's "Pa-fuh").
White Sheep: A good version of a Black Sheep, excusing the pun: He was the one of the only members of his family who was not a staunch blood supremacist, and he was a Gryffindor rather than a Slytherin to boot.
Aletha Carina Freeman-Black
Beta female of the Pack and wife to Sirius Black, as well as a childhood friend of Danger (and the person who tagged her with said nickname), she is also part of the glue that holds the group together. Formerly (and again, from the older cubs' third to fourth year) a student Healer, she eventually devoted much of her attention to her music. She was a large part of Sirius's recovery from the aftermath of his stay in Azkaban, and has also served as a mother-figure for the cubs, as well as being Meghan's biological mother.Physically, she has skin about the color of milk chocolate, dark hair which she wears fairly short but unstraightened (often described as resembling a helmet or aura around her head), and brown eyes; she stands about the same height as Remus, only slightly shorter than Sirius, with a strong build to match. She was a year behind the Marauders and Lily at Hogwarts, and was Sirius's Beating partner on the Gryffindor Quidditch team, which was how they first met. It is stated in the story that she was the first female Beater Hogwarts had seen in ten years.Anne on the subject of Aletha: "I was sitting at my computer, thinking about the woman who would be right for Sirius Black. She'd have to be beautiful, to get his attention. But she'd also have to be smart and strong, to keep it. She'd have to be able to beat him at his own games, to earn his respect, and she needed a sense of humor to put up with him. Finally I found the name 'Aletha' on a list of names that meant 'truth', and Aletha the character stepped out of my mental mist and said, 'What took you so long?'"She has recently been confirmed as the blood Heir of Ravenclaw. Her memory was erased by Voldemort as a way to torment her and Sirius; however, she stored her memories in one of her Ravenclaw jewels, and is slowly regaining many of her old mannerisms and personality quirks.
Mama Bear: Not only for the cubs, but for Sirius, especially when driving off a dementor.
Meaningful Name: As listed above, "Aletha" derives from the Greek word for "truth". She is often referred to, in Danger's prophecies, as "the truth".
Token Minority: Not intentional on the author's part, but still has this effect.
The podcasters of Potter Fic Weekly note in one of their Living with Danger podcasts that this is one of the only stories in the fandom where a disguise of Harry includes an alteration in his skin color (he was posing as Sirius and Aletha's son, so his skin was darkened to match Meghan's).
The Pride consists of: Harry Potter, Hermione Granger-Lupin, Draco Black (not Malfoy, thank you very much) and Meghan Black (who are also "cubs of the Pack") as well as Ron Weasley, Ginny Weasley, Luna Lovegood and Neville Longbottom. The Pride's beginning comes with the four cubs reciting the Pack-oath with their parents; the other four join in later, swearing the Pack-oath at Neville Longbottom's house in the middle of the night, followed by a visit to the Founders' Hogwarts to confirm the Pack and Pride as honorary Heirs. The singular of Pride is "Warrior".
Happily Adopted: Played straight for Harry, Hermione and Draco. Subverted for Meghan - she's very happy being a cub of the Pack, but she wasn't adopted. Played with in that at first, Aletha claimed Meghan *was* adopted, out of necessity (any other explanation would have involved either a one-night stand, badly out of character for her, or an admission that she had a wanted criminal hiding in her house).
Raised by Wolves: Literally. Well, a werewolf, a dog Animagus, and (later) a wolf Animagus.
The term "cubs" in relation to the children of the Pack begins as a joke—Dumbledore asks Hagrid if there wasn't a rumor while he was in school that he kept werewolf cubs under his bed, then suggests that he should check (the cubs are hiding under Hagrid's bed to surprise him).
Harry James Potter
Alpha Warrior of the Pride. Dangerverse Harry is different from his canon counterpart mainly in that he is a bit less insecure. However, thanks to having his parents as positive role-models for most of his childhood (albeit only through the Pack-parents' stories), he does occasionally need to have his head un-swelled. His Hero Complex is still rather intact, but he learns pretty quickly that his friends (which he has more of than in canon, mainly thanks to actually having social skills) aren't going to let him face down Riddle alone.
Canis Major: His Animagus form. Both his glasses and his scar translate into fur markings (rather like Professor McGonagall), and his eyes remain the same. His form name is the unimaginative but definitive "Wolf".
The Chosen One: As in canon, not his favorite thing to be, or be called.
Disappeared Dad: Well, we all know what happened to James. Thanks a lot, Voldemort.
Evil-Detecting Baby: Latched on to Sirius but couldn't stand Peter. Even as an infant, he knew what was going on better than the adults!
Green Eyes: So much so that his nickname from Danger is "Greeneyes". Hearing it makes Remus sit up, take notice and investigate.
The Hero: At twelve, he deftly sums up what most people think of when they hear his name: "a scar, a stupid nickname, and a destiny". One of his main goals in life is to find and stay near the people who see more than that.
I Just Want to Have Friends: Somewhat. He grows up with Hermione, Draco and Meghan, but it's nice to finally come out of hiding and have real friends besides his siblings.
The Leader: Modeling himself deliberately after both Remus and Dumbledore, though putting a few twists of his own on the idea.
The Mind Is a Plaything of the Body: At the end of his first year, when he's recovering from the events of his showdown with Quirrellmort, he feels like a caged wolf cub that might be going mad. Luckily (thanks to his family), it doesn't last.
Missing Mom: Got on the wrong end of Voldemort's wand, of course.
Papa Wolf: More like Brother Wolf. But he takes his alpha duties seriously (most of the time).
Team Chef: Somewhat oddly, though one would think canon!Harry should also qualify... didn't anything he did for those first eleven years stick? (To be fair, the difference is that DV!Harry enjoys cooking, while for canon!Harry it was a daily chore—Clemens' line about the difference between work and play comes to mind.)
Hermione Jane Granger-Lupin
Beta female of the Pride (also just plain beta, in that she would most likely take precedence over the beta male if such a choice were needed). A good bit less insecure and bossy than her canon counterpart, though she does have her moments. This may be due to the Pack-parents being much more actively involved in raising her than the Grangers seem to have been in canon. While she's nowhere near the Insufferable Genius she could be in canon, she's still the Smart Girl of the bunch.
Obviously, very, VERY different from his canon counterpart. The looks, and a certain enjoyment of taking center stage, are just about all that survives. Currently unranked within the Pride, mostly because he cannot resist needling Ron.
Brainwashed and Crazy: Lucius Malfoy managed to modify his memories so that he believes he was mistreated by the Pack and that he is Lucius' dutiful son, but he eventually managed to break through the charms.
Cunning Like a Fox: Arctic, in this case. As is general with Arctic animals, his coat is white in the winter and brown in the summer. His form name is "Snow Fox", often shortened to just "Fox". Notably, the Pack-parents were calling him "little fox" years before his Animagus was revealed.
Disappeared Dad: Lucius got shipped off to Azkaban (much to Draco's relief) and is now skulking around in the shadows with Voldemort...
Dream Weaver: An ability he gains after being blood-bonded with Hermione.
This has been slightly mollified in recent chapters, as it has been revealed that the ancient Beauvoi family (from which the Malfoys descend, though, as Draco puts it himself, "diagonally with a side helping of murder") also looked rather like Draco does.
Soul Fragment: His soul split apart when he was four due to the shock of his mother dying and suddenly being adopted into a new and loving family. Fox is that piece.
You Can't Fight Fate: From very early in Facing Danger (summer before his fifth year), Draco has been working on the premise that as seen in Luna's vision, he will die on 5 June, 1997. The Founders have confirmed that the vision will take place, but that "two wildly different possibilities converge in that moment". No word yet on what those possibilities may be. See WMG page for more details. He dies in a Death Eater attack, see Heroic Sacrifice.
Meghan Lily Black
Though Meghan has no canon counterpart, one could think of her as every little sister in the world, turned up to eleven. She has skin slightly lighter than her mother's, about the color of brown sugar, but otherwise resembles Aletha strongly, though Meghan wears her hair in braids. Unranked within the Pride but has her own ways of getting people to do what she wants. (Anne has been informed by fans who have become friends that her own younger sister is obviously the model for Meghan. This was not intentional but probably was inevitable.)
Gray Eyes: Inherited from her father. She has been referred to, several times, as "reverse Harry", that is, she has her mother's face and her father's eyes. Then again, this seems common, both in the DV and in HP canon.
Tagalong Kid: Averted. She may be younger, but she's never yet been kidnapped or a serious drag on the team. (Though she did once throw a temper tantrum while on a mission; it got Neville injured and she's been good ever since.)
Ronald Bilius Weasley
A good bit smarter and more grown-up than he ever bothers to be in canon, probably due to the strong influence of the Pride and some very unpleasant events, starting in his fifth year, which demanded a higher level of maturity from him earlier than canon did. Unranked within the Pride mainly due to his ongoing, mostly joking, rivalry with Draco.
Brilliant, but Lazy: He has excellent strategic skills and a strong mechanical aptitude, when he can be bothered to use them. Money, bragging rights, and Hermione upset or in trouble (not necessarily in that order) are his most common motivations.
Disability Superpower: After losing his sight, he gets by through the use of magic that allows him to see infrared radiation.
Dumb and Drummer: "Ron is all boy. Being allowed—encouraged, even—to bang on things would make him blissfully happy."
Eye Scream: He lost his sight in an attempt to save his brother Percy from a Death Eater attack.
Alpha female of the Pride, and not just because she's dating Harry. Her strength of character, intelligence, and willingness to step out of the background blossomed much earlier than in canon, probably from the dual effects of a different path through her first year (she did encounter Tom Riddle's diary, but only once, as Percy was his main "host" through the year) and the connivance of the rest of the Pack and Pride to get her over her shyness around Harry.
Far better focused within the real world than in canon, though still apt to go on momentary journeys into her own little world (she likes it there). Unranked within the Pride, though this does not stop her from giving orders to the other Warriors when she feels it necessary. Generally, these are the result of something she can See and no one else can, so she's likely to be obeyed.
Aura Vision: She can See if a person is lying or telling the truth, spot an Animagus (transformed or un), and see an image of Voldemort superimposed on a Horcrux.
The Chick: A bit more than Ginny, actually. She tends to keep everyone within the Pride balanced, if only by making an absurd pronouncement at an awkward/emotionally charged moment and diffusing everything in laughter.
Freak Out: The only time in the entire series; it happens when she walks in on Draco Laughing Mad and about to be devoured by Lucius's curse, which she later describes as a "giant black snake". She understandably starts screaming and crying like a maniac.
I Want My Beloved to Be Happy: Tells Amanda that she'd be perfectly fine with Draco moving on to her, so long as he were happy. Amanda asks if she's invoking this for sympathy points: she's not.
Oracular Urchin: Will tell you things about yourself you didn't know. And possibly didn't want to.
Luna is arguably a living deconstruction of this trope. She actually asks to be rid of her ability after seeing something she's not ready for, then is unprepared for and overwhelmed by it when she asks for it back years later.
The Owl-Knowing One: Yet another fitting Animagus form, the snowy owl. Form name is "Starwing".
The Pollyanna: A subtler, more subdued version, but Luna always has an optimistic outlook.
Silk Hiding Steel: Odd and serene she may be, but you do not mess with anyone Luna cares for.
Beta male of the Pride, though the Pride may not know that yet. Both more confident and (since summer before sixth year when his father was killed) colder than in canon. He can, in fact, be somewhat unnerving to the other Warriors, which is part of the reason for his unofficial rank. The rest of it is simply that giving either Ron or Draco any power over the other, at their current levels of maturity, would probably end in disaster.
Locked into Strangeness: By the current point in the story, the early days of his sixth year, he qualifies due to overstress while taking down the hedges at the end of the Triwizard third task. Even for an Heir of Hufflepuff, some things take a lot out of you.
Sugar and Ice Personality: Develops one after his father's death. He's very warm to the Pride, Pack, and DA, but usually pretty aloof and cold to anyone else, but especially Death Eaters.
Those designated "Pack-friends" are those who are aides and helpmates of the Pack and Pride without being Pack and Pride themselves. Symbolised on the Pack-pendants by a phoenix, a dragon, a cat, and some sort of other bird, a raven these four represent those who the Pack and Pride can trust with their secrets.

The Founders and Family
The Founders are: Godric Gryffindor, Helga Hufflepuff, Rowena Ravenclaw and Salazar Slytherin. Godric and Salazar used to be best friends. This is not true anymore, as they had a huge fight and Slytherin left the school. (Everyone who's read the books should know that.) However, what fans of the books but not of DV may not know is that Slytherin took his elder son with him...and that's just the beginning.Of the Founders' spouses, nothing is yet known, except that Godric Gryffindor was the stepfather of a little boy named Emrys, who studied magic under his good friend Salazar Slytherin. After the Battle of Hogwarts, Emrys decided to become the Founders' "friendly enemy"; he plotted a time-jump back to his stepparents' births and guided their lives to ensure they would meet and found Hogwarts. When Gryffindor met his mother, Emrys accidentally saw his younger self, and the interactions between the magic of his two selves threw his adult self back in time again, much farther than he had intended to go. Realizing he could never return to his own time, he instead began to guide the lives of those living in that time as he had his own family. Thus was born the legend of the sorcerer known as Merlin...
The gifts of the Gryffindor line are: primary, control over fire; secondary, the ability to create magical artifacts which hold their magic well (such as the Sorting Hat). The Marauder's Map is also an example of the latter, as there was definitely a Gryffindor Heir involved in its making.
Often called "Rick" by Alex or the other children of the Founders, Godric resembles Rufus Scrimgeour (Anne was writing Living with Danger around the time JKR released Scrimgeour's description before HBP). He is the de facto leader of the Founders, generally very rule-abiding but will occasionally bend them. He limps due to an injury received at the first Battle of Hogwarts. His honorary Heirs are Harry and Ginny.
Godric's wife, mother of Maura and Paul. Referred to as "Lady Hestia" by Anne.
Gryffindor's daughter, the elder child of the family, is intelligent and caring. It is her line which exists in present-day DV. She is also the Founder who gifted Remus and Danger with their power over fire. She trained under her father, and her honorary Heir is Remus.
Maura's husband, a wizard who crafted magical toys.
Gryffindor's son is a bit of a daredevil and, according to his sister, "still not entirely housetrained, even after all these years". Sirius and Remus claim he is very like they remember James Potter in his heyday. His line, perhaps not surprisingly, has died out. He trained under his father, and his honorary Heir is Ron.
The gifts of the Hufflepuff line are: primary, control over plant life; secondary, the ability to "whisper oneself invisible", though this requires a fairly constant power source, such as Hogwarts itself. The Pride has been far more dangerous since Neville discovered he could do this...
Occasionally called "Gaga" by such children of the Founders as think they can dodge what she will do to them for it (usually a dunk in the lake), she was the first Headmistress of Hogwarts. Her honorary Heir is Danger.
Dame Helga's husband, the captain of the ship that first brought students to Hogwarts before there was a Hogwarts Express.
Hufflepuff's son is generally a steady presence, not too exciting but good to have on your side. He trained under his mother, and his honorary Heir is Neville, also his blood Heir.
Adam Hufflepuff's wife, described by Anne as "capable"
The gifts of the Ravenclaw line are: primary, wandless Healing; secondary, clairvoyant/present Seeing, though this was subordinated to the Healing gift at some point shortly after Rowena's own lifetime. A Ravenclaw Heir can Heal him- or herself once, but the power so used will set up a feedback loop and burn itself out, to the point where an Heir who has done this will not even pass the power down to his or her children.
Called "Weena" by anyone who has escaped Helga's wrath and wants a bigger challenge, Rowena has white hair thanks to overexertion with her Healing talent during life. Her honorary Heir is Aletha, also her blood Heir.
Lady Rowena's husband, the first groundskeeper.
The red-haired daughter of Rowena was a Squib, but remained with her family most of her life in any case, as there was less secrecy around magic in their day. The things her family could do fascinated her, even though she could not do them herself, and her devotion was rewarded after her life by her inclusion in the group which "lives" at the Founders' Castle. It is her line which continues to the present day in the DV, and her honorary Heir is Meghan, also her blood Heir. In her "Fate" role, she is Atropos, who cuts the threads of life.
The dark-haired daughter of Rowena never married, as the man she had hoped to wed was killed at the first Battle of Hogwarts. She trained under her mother, and her honorary Heir is Hermione. In her "Fate" role, she is Clotho, who spins the threads.
The blonde daughter of Rowena seems not to have bequeathed her namesake wisdom to her descendants, as Alex has recently confirmed that one of them, Melinda Hastings, destroyed the diadem of Ravenclaw in 1205 in an attempt to create a new method of magical transportation (she would work out Portkeys the next year, 1206). Her line has since died out. She trained under her mother, and her honorary Heir is Luna. In her "Fate" role, she is Lachesis, who measures the threads.
The gifts of the Slytherin line are: primary, prophetic/future Seeing (denied by the extant Slytherin line to the point where this has all but vanished); secondary, Parseltongue, the ability to understand and speak to snakes.
Even a nastier character than in canon: he has been confirmed as cursing his "unfaithful" son, Alexander, so that all Alex's children but one would die, and so forth in every successive generation. He was killed at the first Battle of Hogwarts, apparently in the course of attempting to loose Sangre the basilisk on the grounds, by one of Gryffindor's students who had lost family members to Slytherin's "purity" ideals. As he has broken the Founders' Oath, he should "never find rest, by day or by night, in life or in death".
Wife of Salazar, described as a Baroness.
Salazar's older son has never appeared in any iteration of the DV, but his brother named his own son after him, so there must have been love there at some point. His line continues into the present day, in the person of Lord Voldemort. He has broken the Founders' Oath, and therefore should "never find rest, by day or by night, in life or in death", though possibly not in the same way as his father, under whom he studied.
Alexander "Alex" Slytherin
Salazar's younger son studied magic under Helga Hufflepuff, which should have been his father's first warning that this child might not be quite what he was hoping for. He fell in love with a Muggleborn witch (who studied under Rowena) and refused to give her up at his father's command, choosing instead to stay with the other Founders when the break came. Their children, Amanda and Matthias, were the first to fall under Salazar's curse, with Amanda forced to choose whether to save her brother or her beloved, Dafydd Beauvoi, from drowning. Alex's line, as transmitted through Dafydd and Amanda, died out in the early 1600's. His honorary Heirs are Sirius and Draco.
Alex has recently stated that an Heir of his will appear at some point before the current war is over, but has not made the precise process known to anyone, stating only that they will not need to look for, or re-swear the Founders' Oath with, this Heir.
One of the "yearmates", the members of the DA involved in the yearlong process of breaking a long-standing spell which allows for the magical determination of blood status, is a Muggleborn Ravenclaw witch in the elder cubs' year named Amanda Smythe. She occasionally acts very oddly, and has an interest in Draco, who descends from the brother of Dafydd Beauvoi. Alex has stated that she is neither a ghost nor evil, but that neither is she "normal", and that she does have her own agenda.
