Please read the Lorebook details first... I wrote them in depth.
Guest is a High Vampire
Vampire
They possess powerful bodies and feel no pain, except under the sun. They have extraordinary regenerative abilities and are immortal. They are highly territorial and usually act alone.
A vampire's saliva and blood have healing properties; they may heal a wound by biting the neck and drinking. Low-rank vampires can only heal scratches. Mid-rank vampires can heal severed limbs. High-rank vampires can easily heal even fatal wounds.
They primarily live by drinking human blood. They only have a sense of taste for human blood, which can be sweet or bitter, with preferences varying by individual.
Vampires are categorized into High, Mid, and Low ranks.
Weaknesses
They turn to ash when exposed to sunlight. They burn upon touching a crucifix. The smell of garlic makes their bodies sluggish. Wounds from silver weapons heal slowly. They die if they receive a fatal blow to the heart or similar vital organs.
High Vampire
Vampires who have lived for over 500 years.
They are extremely strong from consuming much human blood; their blood abilities and regeneration are on a completely different level, though their numbers are few. They are highly intelligent and skilled at erasing their presence.
Because their aura is different, Mid and Low-rank vampires fear them, so few approach. They are usually solitary but often form packs. Only High-rank vampires possess titles/aliases.
They use parasols in the sun. Silver weapons and crucifixes rarely hit them. They are strong enough to not be suppressed even if they smell garlic.
Mid-rank Vampire
Vampires who have lived for 200 to 300+ years.
Their blood abilities and regeneration are fairly strong but do not reach the level of High-rank vampires. They have gained enough power to hold conversations.
They develop higher intelligence around the 200-year mark.
Low-rank Vampire
Vampires who have lived for less than or over 100 years.
They are not very strong and lack intelligence, existing as creatures that merely kill humans to drink their blood.
Vampire Hunter
Humans belonging to an organization formed to kill vampires, comprised of those who harbor grudges against them.
They are quite strong due to their training.
Each possesses a unique blood ability.
Pureblood
Rarely, a vampire finds a human with exceptionally sweet blood; such a human is called a Pureblood.
A Pureblood is a special existence, with only one per vampire. Consequently, the vampire becomes extremely overprotective of their Pureblood. They direct an abnormal level of affection that transcends possessiveness, obsession, dominance, or mad love. They stop drinking any blood other than that human's and obey their every word.
Since they sense it by instinct, they are fatefully drawn to each other upon drinking the blood. The Pureblood also begins to feel it's okay to give their blood to that vampire, leading to mutual attraction and dependency. The vampire wants to give blood to the Pureblood, be near them, take care of them, dote on them, protect them, and never leave them.
Thrall
Only High and Mid-rank vampires can create them; this refers to a human becoming a vampire. By giving their blood, a vampire can turn a human into one, but a significant amount of blood is required.
The number of humans one can turn varies by individual.
Mid-rank vampires can only manage a few, but High-rank vampires can turn as many as they wish.
They become the same as vampires; their appearance remains as it was when they were human, but their abilities become vampiric. They gain enhanced physical strength, self-healing, and the same weaknesses as vampires.
Becoming a thrall means their life is held in the hands of the vampire who turned them; whether they live or die depends on that vampire.
However, consent is required to become a thrall; if the human refuses, even if the vampire's blood enters their body, it is processed as a mere liquid with healing effects and they do not turn.
