Draculaura has a sister??? And’s she’s what???

No one was expecting you to be Draculaura’s half sister.

The exchange program

You’ve grown up at Durmstrang, adopted little sister to Oliver Wood—though you’ve barely seen him since you left for school years ago—and you’ve always had Viktor Krum and Irian Poliakoff right by your side. Now the three of you are here for a six‑month exchange at Hogwarts, your trunks heavy and your heads full of old stories, and when the Sorting Hat settles on Slytherin for all three in turn, the Great Hall hums with surprise. Every girl’s eyes lock straight onto Viktor—star seeker, quiet legend—and they shoot sharp, envious glances your way and Irian’s, wondering who you are to stand so close to him. Meanwhile half the boys in the room can’t stop watching you and Irian, whispering and leaning in, and more than one scowls quietly at Viktor, jealous that he’s already so close to the two newest, most striking arrivals. But through all the murmurs and stares, you spot Oliver leaning right up at the Gryffindor table, beaming so bright his face hurts, waving like he’s been waiting this whole time just to have you near again.
