imagine this: wei wuxian the most terrifying Hufflepuff ever
Worldbuilding:
Wen Ruohan, the minister of magic, is starting a war against the other strong/powerful/old wizard clans
WWX, 5th year Hufflepuff (I feel like he would fit in well with all houses but his most prominent quality is his loyalty); JC, 5th year Slytherin (all that political manuvering that being a sect leader that young and buiding lp that quickly back to strengh. you tell me he isn’t made to be a slytherin); and JYL, 7th year Gryffindor (that girl got a backbone of steel, tell me otherwise - you can’t one look at phoenix mountain and all your arguments wither away) are the only survivors of the massacre of the Jiang Family. They’re being kept alive as political slaves or sth like that
WRH sealed their magic or sth
WWX, JC, and JYL (because I stan Yunmeng trio) begin to dabble in dark arts.
(No one ever used them and survived or stayed sane so it’s a pretty narrow exploited path no one knows anything about.)
They figured out how/why everyone that used it died/went insane: their magic and it fought against one another.
They come to the conclusion that they need at least one dark arts user and that for them to stay healthy and sane the seal put on their magic will have to be made permanent.
TOGETHER they decide on WWX: JYL is sect leader after their parent’s death and has to stay that way to protect her left brothers, after all: the Jiang name still holds power. It can neither be JC because he’s her heir until she gets a child (or adopts) and like in the previous case: a sect leader/potential sect leader can’t use a heretic magic. also their family magic would fight with the dark one. So it’s left to wwx who was never a member of the main family of the Jiang clan and just the best friend of JC, which made JYL adopt him as their brother in her mind.
So they seal WWX’s magic permanetly and with dark magic he kills WRH and his assosiated (not all the Wen’s because fuck genocide) very publicly (because WRH never leaves public in fear of assasination)
They unlock JC’s and JYL’s magic. They go back to school.
Since JZX (JYL’s fiance) now has to marry in, he was only heir while JYL was a sect leader) (we’ll get a Jiang Ling and ) JGY, the only other child having been acknowledged by JGS before he died under mysterious but nothing too OOC for himcircumstances, becomes heir. (yes jgy killed him so he wouldn’t bring in more half-siblings, that could threaten jgy’s position)
Happy with his position and with a better relationship with his half-brother, now that he isn’t a threat to jgy, jgy doesn’t care about what wwx is doing, maybe he even helps him a bit. after all it would do no good for people to connect the jin name to a criminal (it would be connected ia a way that jzx was tecnically wwx’s older brother and he came from jin sect)
so with jgy and jyl’s protection wwx is allowed back to school for his 6th and 7th year even with his dark magic.
(If you’re so inclined you can imagine a bit romance between him and the hufflepuff seaker, 6th year lwj ( he isn’t loyal in the way wwx is: to everyone he has a dept to and who he care for. He’s singedly devoted with his whole being to a single person - can you guess wo ;)?):
with everyone scared of wwx he spends a lot of time with his siblings and in the library where he can learn new things, honestly it’s a wonder he wasn’t a ravenclaw. there he gets closer to lwj. and after 7-8 business weeks of pining and a big misunderstanding he confesses to lwj right as he saw the snitch - he fell from the broom and their team lost but lwj is ok and everyone too terrified of wwx (and the most stoic hufflepuff) too say anything.
Wangxian spend the rest of their hogwarts days being the couple you don’t want to meet alone in a hallway (for two reasons ;) ) and wander the world after it for a few years, helping people and creatures, hunting monsters, being disgustingly domestig and horny in front of everyone’s salad)
