This is practically just me rambling but my mind has been playing on loop, on repeat, the idea of a vampireAU Reinsuba fic, I am such a sucker for medieval old timey even Victorian sets and vampires with religious undertones and yadda yadda,
I've written like around 1k words in a spur on some random Monday about like the prologue of such an AU and it's just been plaguing my mind so here's just like a rough idea,,
-I think it's quite obvious but Reinhard as a Vampire Slayer and Subaru as a vampire.
-Od Laguna being treated as more like a Christian god-esk, churches to pray for blessings etc, this would solidify how Reinhard would be seen as like, a sign of Of Laguna's existence and benevolence (and the title of sword saint in of itself as one of the major blessings to be bestowed) seen as more of an entity instead of a mechanism.
-This might be crazy but no spirits or affinities, the only real magical properties would be Reinhard's blessings and the existence of vampires. Beatrice still exists, maybe just a trapped vampire waiting for the day a hunter comes to slay her instead.
-Witches are seen as the roots of vampires, the cause and reason for their existence. Witch factors are seen as gifts bestowed upon selected vampires and passed down whenever one passes (it's a big deal to kill one I mean) RBD kinda falls into this category of gift, Subaru is oblivious of RBD until his meeting with Reinhard.
-I'd like to keep the theme of Subaru being rather weak going, so by vampire standards and human standards he is still very, very, inexperienced and weak and is basically never perceived as a threat even if he is a vampire. Though he can go longer without consuming blood than other vampires can, and he has the ability to hamper his bloodthirst.
-Felt, (Contrary to popular belief) is not a vampire, she's just blessed with unfortunate genetics of looking VERY SUSPICIOUS. Cue hijinks.
-Subaru had been isekaied like around 2 years (give or take) before main timeline and holed up with Felt and Rom in the meanwhile when he realized he was a vampire, initially thought Rom housed vampires because of Felt's VERY SUSPICIOUS looks and once proven wrong, Rom did take pity on him when they realized Subaru's threat level was close to nonexistent and let him stay as long as he could contribute.
-Vampires have a subtle scent of blood that will always cling to them, usually in history this was used to aid Vampires in finding other Vampires but trained hunters can hone their sense of smell to also capitalize on this, the miasma is tied to the witches which is another very telltale sign. (Not all vampires have miasma.)
-Witches cult usually recruits vampires, their goal is more like vampire superiority I guess.
-Emilia is not a vampire. Totally not a vampire. No, not a vampire.
- Vampire pecking order =
Turned Vampires (bitten, later turned.)
Partial Vampires
Born Vampires
Fiends (Basically on par with archbishops I suppose?)
Witches
-Subaru is considered a Turned Vampire as he was turned into a vampire when he got isekaied, vampires just have a natural sort of second sense to this pecking order so even if he wanted to, he wouldn't be able to masquerade as a born vampire.
-Reinhard cannot turn into a vampire, Subaru stop nibbling on him it's not going to work. Love the enthusiasm though.
-Demi-humans don't exist, arggg I know this might cause me some plot holes to try and frantically patch up which I did however expect when it came to wiping magic off the table as well, but the setting is old timey medieval vampireAU, for the sake of it Demi-humans are partial vampires, not under the same scruntiny as normal vampires because partial vampires don't have bloodlust and cannot turn humans into vampires.
I might sprinkle more stuff later on as it's quite late atm and I might just be missing some stuff, the title is "Of Blood And Silver", or OBAS for short.
Idk let me know what you think!! I'm a huge sucker for VampireAUs or RoyaltyAUs lmao
Edit: I think this is relevant enough to preface, the au is reinsuba centric, it's not world building centric.
Some plot holes are just going to be plot holes because if it was to be adapted into a fic, they'd all be background plot holes in places that the fic would never be focusing on, I won't be going in depth about things that wouldn't pertain to the main point which is, well, ReinSuba and their relationship as the main plot.
Also I'm writing this half awake so please give me some benefit of the doubt as I can barely keep my eyes open let alone try and activate my neurons to remember plot lmao
