ALRIGHT HERE my vampire biology/physiology headcanons, to go with this worldbuilding post here.
DISCLAIMER: I am not a biologist, or scientist, and have made only the most cursory research to see if something fits. In addition keep in mind that vampires are also MAGIC and I will be including that in my headcanons. For fucks sake they turn into tiny BATS, there's only so much logic you can apply to loss and gain of mass. Vampires to me are equal parts bug/bat/cat.
I withhold the right to change any of this in the future, and it is not a hard rule. I am so sorry in advance for the wall of text, I promise I tried to keep it as concise as possible.
Fact 1: Vampire noises
Bats in real life DO purr, but it's not very audible to humans. Vampires purr/chirp/hiss like MOST things in nature (spiders/bats/cats), which is vibrating something against something. It happens in their chest and completely bypasses the vocal cords. Half the time they are not conscious they are doing it.
Young vampire (stuck in a trap): >:( Humans: ... What's that noise? Young vampire: (still actively making distress noises, arms crossed) >:( "What noise?"
Vampire chirping doesn't have any more meaning besides call and response- it's meant both for a vampire saying, "I'm here!", and also say, "I hear you!". Also for sires to enforce curfew. This is the silliest most self indulgent thing I have vampires do, because I think it's very funny if they don't have any control over it when they're young.
Shelby: Scott I have the most fucked up hiccups you would not believe. Scott: :)
Fact 2: Blood drinking
Blood drinking can have a lot of different meanings between vampires, all depending on the context. Just like grooming or growling or yawning in animals can mean a bunch of different things depending on reason and context, or screaming can mean a bunch of different things with people.
A higher ranking vampire pinning another and drinking from them could show dominance, such as, "I'm bigger and stronger than you, I'm making you smell like me, and also getting a meal to boot. Eat shit idiot."
A higher ranking vampire letting/forcing a lower ranking or less powerful vampire to drink from themselves, could be indulgent and patronizing- as in, "You are not as good at hunting and providing as me, so I'll show you how much better at it I am. You're welcome. Eat shit idiot."
Two vampires who are very close to each other may share blood as equals, just like kissing, or hugging, or any shade between and beyond. Just a way to share intimacy!
A lower ranking vampire, or one trying to join a coven may try to gain favor by letting another feed of of them. "Look! I went hunting, and now you don't have to lift a finger, aren't I good at contributing? :) Please don't kill me." :)
And a sick/injured vampire might feed off another/get blood fed mouth to mouth if they aren't able to hunt/swallow themselves. (It's why covens even evolved in the first place!)
Fact 3: Senses
Literally what inspired all of my vampire headcanons/fics is cats smacking the shit out of each other. (My cats smacking the shit out of each other.) MOST of this does not happen consciously. Owen for instance doesn't know why he dislikes Scott acting like his "Sire" so much, but it's because he doesn't smell right. SCOTT on the other hand knows exactly what he's doing, and makes sure to let the coven wear his clothes and sleep in his crypt.
Forcible grooming/scenting is a way of establishing hierarchy, just like cats and other big predators. Also I think it's very fucking funny.
Vampires can also typically smell who's been fed off. This keeps them from A: Stealing another vampires meal on accident causing conflict B: Accidentally killing a meal that has been fed on recently.
Vampires have incredibly sensitive hearing, and have a very limited version of echolocation even in human form, once they reach a certain level of maturity.
All these excellent sense of course are sometimes as much a detriment as they are a boon.
(Abolish with a can of pennies and a grudge: )
Fact 4: Venom
Venom in vampire saliva keeps prey from bleeding out when applied correctly. It also has a narcotic effect, more effective the more mature the vampire is, and is pretty antimicrobial.
(Legs deeply considers having the town vampires spit in a bottle, before Cleo starts smacking him over the head.)
It also effects other vampires! A sire's venom is very good at subduing their fledglings, and an elder vampire might weaponize it on weaker/less mature vampires.
Fact 5: Touch
Vampires are VERY PHYSICAL. They touch WAY MORE with affection, and inflict FAR MORE VIOLENCE when irritated/showing aggression. They do not think this is odd, although it doesn't change blatant acts of abuse/violence from being so.
Fact 6: Hibernation
When very very injured, or under less than hospitable conditions/stress, a vampire can slow themselves down to basically an actual corpse. This has a pretty high mortality rate honestly, and is generally a Big Fucking Deal. You do not do it lightly.
Let's use Louis as an example.
In "Grim Purpose", Louis was very very horribly injured. He shut down to repair himself, and Owen (under a large amount of stress, and sensing some less than hospitable conditions) put himself into a hibernation with him.
There were differences between the two! (Just like Scott's forced/spelled hibernation was different from both of these!)
TW: Burn injuries/Insects: I think Vampires DO bury themselves when injured! It partly contributes to the myth of the living dead, and vampires living in graveyards. For Louis (and any other badly injured vampire), the dirt and microbial life and insects eat all of his dead and rotting skin, so the small amount of energy he had could go towards healing the live parts. The lack of oxygen also helps them heal. (This is where they are more insect-like to me, shutting down in inhospitable conditions.) Vampires do not get traditionally infected, and most things would not bother eating "live" vampire flesh/muscle/etc.
Owen was in more of a guarded hibernation. Vampires (again, an evolutionary trait) are able to hibernate together, protecting the more vulnerable. It's why Owen was vaguely awake and conscious, enough so to wake up when the beacons went up and Oakhurst was disturbed.
Pyro might have done the same for Scott once upon a time, or a sire might expect it of his fledglings. I imagine Scott having reluctantly done it once upon a time, for his fucked up freak of a sire who I have yet to name.
Perhaps Avid is still vampire enough for something similar to happen to him!
It's also why Scott sarcastically talks about Owen's 200 year hibernation not really being him getting older, and more like a fitful nap in "brooding wings"- because it is a sort of stasis.
Fact 7: Vampiric Abilities
Most vampire lineages have their own trademark specialty, or ability. For Goldsmith's it's hypnosis. For Louis' father, it was wings and unnatural strength and ferocity.
For Cleo's mother, it was something different, I haven't decided yet. Maybe something more magical, or an affinity for deadly venom.
This can be handed down from sire to fledgling, or from vampire to biological (human or vampire) child, to be revealed after they're turned. (Or perhaps in their descendants, far down the line. Cough cough Abolish cough cough.) This doesn't mean you can just funnel all vampiric abilities into one line, as tempting as that might be. (Many vampires have tried. Vampire have nothing but time and boredom to alleviate.)
Eventually one or two traits will dominate, and continue down the line, barring mutation. it's actually a good way for lineages to disappear.
(Pyro and Shelby's hypnotic Goldsmith abilities are reflected in different ways, since they are not fully mature yet. I will save that for spoiler reasons.)
Let's use Louis as another example.
Fact 8: Louis
As I mentioned in the previous post, vampires ARE able to have children very very rarely. These children are born human for all intents and purposes, and if they are never changed simply hand down a bit of a genetic time bomb to their descendants.
Abolish is an example of this. It's what resulted in him being a half vampire in canon after being "cured"- his genetics were already primed for vampirism.
(He also has his own lineage ability- I wonder if anyone can guess what it is...)
Normal human children cannot be turned, as their body rejects the change without a physical/hormonal maturity, and they will simply die. But children born of two vampires are able to safely make the change.
This does not mean it is proper, it was VERY very unorthodox for Louis' mother to do this, since it affects their development, and takes far longer to reach biological maturity. (But she had her reasons.)
Louis inherited the Goldsmith charm and propensity for leading, although he did not get the full hypnotic ability. He inherited his fathers wings, although he did not get quite the same ferocious strength.
Owen took far more after Louis' father. If he got anything from the Goldsmith's it's his dramatics- but he was honestly probably like that before coming a vampire.
This is all stemming from Owen's commissioned art in his videos, where Owen and Louis canonically have wings by the way, and is part of what kicked off most of my fics. Legs in canon would also have had wings, and probably none of the Goldsmith charm/ability. In fact, after getting turned he might have been stronger than Owen.
Okay I think that's it for now. Christ. Send tweet.
