Personally, I'm of the opinion that vampirism, while a curse of magical origin, also has some biological components similar to that of HIV
In that it changes the afflicted person's DNA
But, instead of reprogramming the body to attack its own immune system, it causes the body of the host to rapidly mutate
In the initial hours or days after being bitten & drained, the newly turned vampire is dead in almost every sense of the word
Their heart has stopped, they don't breathe, they've lost all body heat, they probably underwent rigour mortis for a bit
Their brain, however, would still show signs of activity long after it should have shut down from lack of oxygen
Physically, they're dead, but mentally, they're simply comatose
That is, until they wake up in their coffins six feet under
Oh! Thatâs really fascinating â Iâve found myself wondering the same thing at times: âHow does a vampireâs body actually work?â Especially, âHow does a curse â something of magical origin â affect the biology and physiology of a technically dead body?â
If you think about it, a vampire moves, thinks, and speaks while being dead. That means the brain must still function somehow, that electrical impulses still travel through it, and that they can send signals to the rest of the body. So yes, I can easily imagine the scene you describe â a kind of death that doesnât entirely shut down the nervous system.
Technically, a vampire doesnât need to breathe to survive, but it does need to inhale air to speak; otherwise the vocal cords couldnât vibrate. So the pulmonary function is intact. If heâs capable of having an erection â and, for instance, Astarion does â it means blood still circulates and can reach the bodyâs extremities⌠even if the heart isnât technically beating. Maybe? Which is contradictory, but there it is.
Normally, vampires donât need to sleep either, yet in BG3 Astarion seems to experience reverie like an elf. Moreover, his teeth and eye color â both determined by DNA â visibly changed after his transformation, as if some genetic strings had literally been rewritten. Same with digestion: his body now only accepts blood. Iâll leave aside the psychological effects here, since weâre focusing on physiology.
Although itâs not the only factor, we can say that DNA also determines the quality of oneâs senses â how developed they are from one individual to another. Therefore, if vampire spawn and full vampires possess heightened senses compared to when they were alive, we can assume that vampirism has intrinsically altered the corresponding strands of their DNA as well. Of course, all of this remains within the bounds of this âscientificâ interpretation.
If I remember correctly, the official D&D manuals only describe the process of creating a vampire spawn, and later a full vampire, without ever delving into the technical or medical aspects of how it actually works â or what the state of âvampirismâ really implies in the transition from living to dead to undead.
What we do know for sure is that, to create a spawn, a vampire must drain its victim, bury them, and the victim will rise as spawn nights later. To turn a spawn into a full vampire, the sire must willingly share their blood (with the specific intention of freeing them â because the sireâs intent and will play a greater role than the blood itself. The blood is merely a medium. In fact, drinking it alone has no effect, just as taking it by force does not). And thatâs about it.
Naturally, other simpler â even banal â traits are described too: hypersensitivity to sunlight, predatory impulses, regeneration, bloodlust, and so on. Plus the usual technical abilities from the stat block. But the rest is all speculation: how exactly the curse affects the body, what remains physiologically active and what doesnât, whatâs driven by this dark animating energy, whether parts of the DNA are literally rewritten or not.
So I think your HIV comparison could work beautifully as an headcanon. Itâs a fascinating explanation that merges both the supernatural and the scientific aspects of how vampirism affects the body of them who suffer it â as if it truly were a kind of chronic illness.
But now Iâm on a roll! Letâs dive deeper and try to figure out how things work within BG3 itself. Even there, everything is pretty vague and somewhat left to chance, in my humble opinion. Still, some details remain quite interesting.
First of all, letâs see what the simple bite feels like.
âItâs like a shard of ice into your neck â a quick, sharp pain that fades into throbbing numbness.â
Itâs not a terrible sensation â it only lasts a moment, just the time it takes for the fangs to pierce the skin. Then the pain turns into numbness, and at that point the feeling becomes muted. At least judging from how the narrator describes it during the bite scene, itâs something you can definitely endure.
Dying from a vampireâs bite doesnât even seem that excruciating â at least judging by how the narrator describes it. Itâs a bit like dying from simple blood loss: you fade away slowly, almost gently, as if drifting further and further from the world and your own body, until you feel absolutely nothing. Itâs a bit like falling asleep â but in the cold and the dark.
Hereâs what the narrator says when you fail the checks during the bite scene and Astarion loses control or if you let him feed freely:
âYou lean into him, losing yourself. You can feel your blood racing, coursing through both your bodies. A gentle, numb feeling starts to spread. You feel a little cold, but thatâs all. There is no more pain, no more fear, no more struggle. Itâs all over.â
Or during the night with AA, when youâre turned into a spawn:
âAs he drinks more and more, you feel yourself fading from consciousness.â
So, after the brief pain of the bite, you simply slip into unconsciousness â along with the blood leaving your body. All in all, itâs a painless, almost peaceful death. And hereâs what it implies, in AAâs own words, when itâs a true vampire doing the drinking:
âTonight I shall drink every drop of your blood. Own your body, kill your mind. It will only hurt a bit; the pleasure will be far greater than the pain.â
Of course, the context of Tav/Durgeâs transformation is sensual, so it makes sense that there are also elements of pleasure. Even though we donât actually know what happens next, since the scene fades out right there â leaving us wondering what exciting (or not so exciting) things might have followed.
But the Ascended vampire mentions two key things that can imply several layers of meaning: âI will possess your body and kill your mind.â
This could be read as a reflection of what it means to be a spawn, for instance. Or it could suggest that becoming a spawn literally involves a brief period of total brain death before awakening.
And not only that â because during that period of time, the brain itself might undergo a sort of ârewriting,â the mutation you mentioned, adapting to its new nature. The same likely goes for the rest of the organs, which would start functioning in entirely different ways.
However, things get a bit tricky here â because while in D&D the process is fairly simple, linear, and very much in line with your âscientificâ interpretation, Larian mixes things up a little, and itâs not entirely clear how the transformation actually happens.
On one hand, Larian seems to suggest that the victim gently fades into numbness and dies â implying they might later be buried, with all due ceremony, and eventually rise again as a vampire spawn in the graveyard, following the âclassicâ process.
On the other hand, though, they introduce elements that contradict this idea.
First of all, Tav/Durge is never buried at all, completely skipping that step from the traditional lore. And no â personally, I donât buy into the âvampire brideâ theory; as much as I find it interesting, it feels more like a narrative shortcut to avoid further complications and loose ends.
Secondly, Larian implies that something else happens after the numbness of death â but before burial.
Now, to soften the playerâs experience, Tav/Durge doesnât actually remember what happened â they only learn about it the next morning through AAâs words:
âYou were drained dry, and at the height of your delirium, I granted you one drop of my own blood.â
Itâs clear that the transformation takes place after Tav/Durge lose consciousness â and that itâs so excruciating it induces delirium. However, itâs possible that AA gave his beloved a small amount of his blood not only to grant them immunity to sunlight (it wouldâve been quite a gameplay problem otherwise â Larian had to patch that up somehow), but also to ease some of the more unpleasant effects of the transformation.
After all, as I see it, a sireâs blood only carries the effect the sire intends to give. The blood alone holds no power â there must be not just permission, but intention. Otherwise, he wouldnât have been able to share Mephistophelesâ blessing, right?
In any case, this directly ties back to Astarionâs own experience â which, unlike Tav/Durgeâs, he remembers all too well, and with horror:
âI remember how it hurt when I turned to a vampire. My body writhed and warped while I was utterly helpless; the grip of death owned my heart, as it beat its last.â
Astarionâs experience was different also because there was no trust or intimacy between him and Cazador â but even so, the common point is that the transformation happened while his heart was still beating. In the streets of Baldurâs Gate. Not underground, before waking as a spawn and clawing his way through six feet of dirt to the surface.
So⌠whatâs the point of burying the poor bastards, exactly? xD
Larian makes it seem less like a necessary prerequisite for transformation and more like some sort of initiation ritual exclusive to Cazador Szarrâs spawn. Lol.
Larian, how many inconsistencies can you possibly cram into one story?
SO⌠first you peacefully fade away, then you suffer like hell â bending, twisting, arching in pain â and finally, after you pass out, already turned into a vampire spawn⌠you just need a little nap to wake up fresh as a rose in a nice, fresh grave? Maybe?
Letâs just say Larian took a lot of liberties here too, leaving plenty of gray, shadowy areas where multiple interpretations can bloom.
All this to say that, in my opinion, your version actually fits better with D&D canon â even through a more âscientificâ lens. The victim gently falls into a deathlike state after being drained of blood. Everything except the brain is clinically dead. The body is buried, and thatâs when the changes begin â slow but relentless, altering the very nature of the DNA. Painful, perhaps, but progressing through the necessary stage of burial. Until, eventually, they awaken transformed underground and have to claw their way out.
Anyway, thanks for sharing this perspective â it gave me a lot to think about, and I really appreciate ideas that mix science with lore. Itâs such a cool angle to explore.
