This thread is beyond embarrassing, not only does it have the awful trips and namefags larping, it also has a near total lack of consistent information or attempts to offer perspectives on the core idea.

'Vampires' are a hominid subspecies which split off some 600,000 years ago that have a number of common characteristics.

This list is not complete, and may not be entirely accurate but serves as a general guidelines:

-Eyeshine, yellow tinge of the pupils in the dark.
-Increased reflexes and strength
-Predated exclusively on humans
-Uncanny valley effect in both their physical aspects as well as behavioral ones.
-Gracile body structure, elongated limbs which contribute to uncanny valley effect, trademark heat attenuation of something with a high metabolism
-superior vision to humans, can see infared.
-Palid skin due to metabolic processes/resource conservation
And so on.

This hominid species likely started due to a galactose-alpha-1,3-galactose allergy that due to genetic drift became fixed, fun fact, you can literally develop this same allergy from rare tick bites. The end result? You can not eat red meat ever again without going into anaphylactic shock. Two exceptions exist: Birds (which would be difficult even for a reflex wired hominid predator) and humans lack this allergy causing monosaccharide. Given time, evolutionary pressures drove these hominids to adapt in order to predate near exclusively on humans; vampires do not drink blood, they eat you.

They exist into the modern day and are a major cause behind unusual or strange disappearances in national parks. They are also extremely rare in comparison to humans, remember the predator prey pyramid? Ten kilos of grass to make one kilo of cow, ten kilos of cow to make one kilo of human, ten kilos of human to make one kilo of vampire.

I have no idea as to their level of intelligence. I presume that they are conscious to some degree

Classic /x/.

>'ugh mindless bullshit larp'
Even if I'm larping I'm doing a better job at it than every single other person to have posted in this thread.

You're a delusional kid. We already posted more sources and ideas on what you call 'biological mechanisms' years ago. This isn't anything new or groundbreaking.

Reposts are better than namefaggotry, larping and the particular brand of attention whoring you tend to do.
