i like that, without context, both marcus and daniel sound like OCs a twelve yr old would come up with

Goodmorning/good evening! I know answering questions about human/human OCs is not your favorite, but I was wondering if you had any headcanons about the Volturi Coven with the OC you previously mentioned? I’m an absolute sucker for Volturi kings fanfic, and how I really got into the fandom, but all the fanfic are hard to find/not very realistic. Thankyou!💖💖

Hey there, anon! I’ll format this response in a “How I’d Write That Fic” sort of way. Hopefully that checks some of the boxes you’re looking for. (And my apologies if it doesn’t!! This isn’t my favourite trope, so there’s a good chance I’m missing some of its more important features.)

The Volturi have a good, practical reason for pursuing the OC: I’m not a fan of “hey, we just saw you and we love you” or even “you’re so miraculous that we’re not going to murder you in the feeding room.” The coven is made up of people who date long-term before committing (Caius and Athenodora, Marcus and Didyme, and even Sulpicia and Aro knew each other for a while before settling down). Instead, I could see them being moved by need of the non-romantic variety. Maybe the OC has a cool gift? Perhaps they’re really smart, in a way that ancient vampires aren’t? They could be really accomplished in their field, and the Volturi just want to collect them, possibly? 

The Volturi catch feelings differently: Look, I’m convinced that Caius isn’t going to willingly sleep with a human. Aro and Sulpicia definitely will. Athenodora and Marcus are kind of... eh. As a result, the coven’s relationship with the OC will go along at five different paces. (Bonus angst points if the OC finds themselves desperately wanting to get close to one of the more aloof members.) 

And speaking of closeness... the courtship has a moral dimension: If you’re thinking of getting it on with a Volturi member (especially the super-culpable ones at the top of the hierarchy), you’re pretty morally grey, if not downright sinister yourself. I’d love to see the OC wrestle with “I’m a good person,” vs. “I’m in love with a vampire.” ... and no cop-outs. If he or she chooses Volterra, that is a corruption.

Each vampire in the coven loves and treats the OC differently: Obviously Aro will chirp happily about their fascinating mind, never let go of their hand, and completely disregard how monstrous this situation really is. (If the person tries to leave, they’re a liability and will be murdered.) Sulpicia thinks immortality is the greatest gift you could ever give anyone, so..... the OC would get a ton of affection and almost no compassion from her. Caius takes to feelings like a duck to neurosurgery. Athenodora is trying her hardest to be too cool for this. (Weirdly, I could see the Athenodora-OC bond being one of the sweeter ones.) Marcus is his usual passive, gentle self. 

The OC ends up being a beloved addition to the coven... but also a weapon/tool: Volturi/OC stories shouldn’t (to my mind) have a completely happy ending. The person lost some of their humanity and threw their lot in with evil vampires. The Volturi aren’t going to be entirely transparent with their newest crush. (I mean, how do you tell someone 3,000 years of secrets, even if you wanted to?) In other words, this OC would end up immortal, with a lot of attention and tenderness around them, but also a creeping feeling that they're in a subordinate position forever. 

Oof, that turned into less of a romance and more of a character study, but here we are.
