okay i’ll bite… tell me your headcanons about the black sisters

i love how deeply and intensely people here conceptualise the house of black in general. i’ve always appreciated bellatrix, andromeda and narcissa as characters but i have never really been one to get deep into it. i don’t know why. i know what we have in fanon but i’m just always really curious about opening myself up to other peoples headcanons…

give me everything !! what do you personally think their childhoods were like. personalities back in the day, even? do you have a favourite? how do you justify or even begin to explain their bad choices / character traits??

i’m so intrigued!!
