durmstrang!sirius and slytherin!marlene | dark!blackinnon au

walburga senses, as most mothers often do, that hogwarts may not be the right place for sirius after all, so before his letter arrives at 11, she ensures his place at durmstrang is secured. he is a black, so that’s easy enough. and while sirius is our fully rebellious teenager that we know and love and doesn’t exactly fit within the black family standards, he can’t quite deny that he’s having a bit of fun learning a few new tricks in his heavily dark arts oriented school.

on the other side, we have a completely surprised marlene after being sorted into slytherin. and yet she can’t quite complain. the views from under the lake are stunning and there’s a lot of comfort surrounding her in her new house. and she can’t exactly claim she doesn’t fit in either because after all, not only his father is head of a department in the ministry, but the mckinnons are a well respected pureblood family even if they’re not considered rich enough to commune with the highest wizarding families.

both sirius and marlene are surrounded by people talking day and night about the dark lord and his promises to build a new world and how he will reward his most loyal followers. neither are particularly interested in it and, at this point, they’re both safe enough for them and their families to not being at risk.

also yes, they’re both know each other, seeing as marlene is the daughter of an important figure in the ministry and the black’s business often times coincides within the realm of the ministry, they were the type of kids who tag along their parents from time to time and they were left to socialize. they got along well enough, to the point marlene had been disappointed when certain heir didn’t joined her in hogwarts.

now let’s cut to after graduation shall we?

sirius ends up joining the death eaters because he feels someone has to look after his idiot brother before he manages to get himself killed.

marlene doesn’t join the order given her acquaintances in hogwarts, thinking she might not be able to keep it a secret and believes her family is safe as long they don’t say anything against the new world order that is expected to take over.

except his father ends up using his position in the ministry to his advantage thinking he might have a chance to impact change for good and death eathers find his involvement with the order. they not only set out to kill him, but as a precaution they kill all of his family with the exception of marlene.

marlene has two choices: either join the order and help them win the war or set out to plot revenge for her family on her own. she chooses the latter.

now, in this au regulus tells his findings about the dark lord to sirius and doesn’t die in that cave. but that doesn’t mean he’s saved.

sirius now holds the power to take down voldemort once and for all and because he heard what happened to the mckinnons, set to reach out to marlene playing a bit of double agent himself.

trouble is marlene has found the death eaters headquarters and manages to bring the whole building to the ground all on her own.

now, any guesses who’s little brother was inside that building at the time of the explosion?

that’s right: regulus black.

what’s sirius to do now? especially since marlene is showing no remorse for her actions, claiming it was regulus choice to join the death eaters in the first place, knowing damn well the risks.
