okay so new vampire update!!!
I am largely following the white wolf rules and history, however, i am including something to the context of a vampire.
What we (should) know:
Lycan/therianthropies and vampires are naturally borne mortal enemies, with vastly similar afflictions, but 99.999999¯ % incompatible. a werewolf bite will kill a vampire and vice versa, further more they can harm themselves by biting each other.
They both seek to dominate the "herd". that is the humans.
Now, the white wolf history is that Caine was cursed with vampirism and cast out of Eden where he met Lilith, murdered her, and came back to earth and started siring his progeny, vampires.
What i am doing now is including Lilith's children.
Lilith was cursed and case out of eden before eve was created.
Caine met Lilith after being cursed and had children with her. her curse was to be able to receive the seed of another accursed human.
Her children, born vampires.
Caine cannot handle passing on his curse and attempts to exterminate his children with Lilith, and proceeded to murder Lilith before returning to the Defiled Eden we now call Earth, where he established the first civilized city.
What Caine did not know was that his children survived, bearing the same level of immortality as Caine himself, and followed him home.
Caine's vampires:
Caine sired 14 vampires. 1 bull, and 13 humans. 5 of the humans survive, but all 13 clans operate.
Cannot endure fire or sunlight. period.
Cannot breed, and are created in death.
They must be dead before they can be undead, and feeding a freshly dead person a drop of vampire blood changes them.
They must be freshly dead to be embraced.
The state of the body in the final moments of life will be the state of the body for the remainder of their eternal unlife.*
Lilith's vampires:
Only 3 out of 5 are living any longer, and 2 are in torpor ("eternal" slumber).
Can endure limited fire and sunlight. not as much as a human of either though.
cannot sire a dead person and can only be born from one of Lilith's children.
Only female vampires can create new children of Lilith.**
Male Children of Lilith are fertile and can pass on their genes, but not their Vampirism.
All children of Lilith have red hair, which grows a deeper blood hue, the more they feed. though they are born with hair white as the driven snow.
"Thin bloods" are a result of bloodlines from dead ancestors; two lines of lilliths and eight lines of caine's vampire children become thinned blood after the 13'th generation. by the 16'th generation, they are no longer any more vampire than a human, but maintain similar appearances.
* if a vampire sired a human being who had a huge gaping gash in their back, that gash would be permanently a part of their physical appearance in their unlife as a vampire.
Likewise, if a vampire who was embraced had no piercings, every piercing (and wound for that matter) they got as a vampire would heal up during the sunlight hours.
**Unlike children of Caine, Children of Lilith are born vampires. as such, they can breed, but only female vampires can create new vampires, and furthermore, children of Lilith, born undead, live through eternity with perfect and beautiful bodies. they mature over the course of 55 years, at which point they stop entirely and live forever as 18-32 year old vampires. However, they will age in the absence of blood, but their age is entirely theirs to control, provided they have the blood to do it with. but that is also universal, not just children of Lilith, but Caine as well, can use blood to affect their appearance.
Some vampires might consider it a waste of blood to "be something they're not" while others see it as an extension of something they are.
