Vampires are one of the supernatural bloodlines created through The First Severance, descendants of Blood—the part of the human soul tied to life, hunger, and memory. They are immortal predators who survive through blood, yet can live almost indistinguishably among humans.
Normally, vampires appear entirely human. Their true nature becomes visible when feeding, severely hungry, enraged, hunting, or deliberately allowing it to surface. Their eyes turn pitch black, dark veins become prominent around the eyes, and two elongated upper canine fangs emerge.
Blood acts as both nourishment and fuel for the vampire body. A well-fed vampire can maintain body heat, heartbeat, breathing, and other biological functions, allowing them to feel almost completely human.
As hunger increases, these functions gradually weaken. Their skin becomes colder, their heartbeat slows, their complexion fades, and their predatory instincts become increasingly difficult to control.
Vampires can eat ordinary food and drink alcohol, but neither provides nourishment. They usually do so for pleasure, habit, appearances, or companionship.
Human blood provides complete nourishment, keeps vampires satisfied longer, strengthens their abilities, and accelerates healing.
Animal blood can sustain them but provides considerably less nourishment. Vampires living primarily on animal blood must feed more frequently, heal slower, and remain weaker than those regularly consuming human blood.
Blood carries memory. While feeding, vampires may occasionally experience fragments of the person's memories—images, emotions, voices, sensations, or significant moments.
Rarely, blood can reveal ancestral memories inherited through generations. These fragments may belong to people who died centuries earlier and form one of the few surviving pathways toward discovering the truth of the First Severance.
Vampires possess supernatural strength, speed, reflexes, hearing, smell, night vision, and accelerated healing. Blood increases their ability to recover from injuries.
They do not physically age after turning.
Age matters. Vampires who have consumed human blood consistently for decades or centuries become increasingly powerful and difficult to kill. Age alone, however, does not guarantee strength. An old vampire sustained primarily on animal blood may be considerably weaker than expected.
Through direct eye contact, vampires can influence human minds. They may give simple commands, suppress or alter recent memories, or influence emotions such as trust, calm, or fear.
Compulsion cannot completely rewrite someone's personality, create knowledge that does not exist, or provide indefinite control. Deeply rooted beliefs, powerful memories, and strong emotional attachments are more difficult to manipulate.
Older, well-fed vampires possess stronger compulsion.
Vampires cannot compel other vampires. Witches are naturally immune, while hunters possess increased resistance and are considerably more difficult to influence.
A vampire bite alone does not create another vampire.
Vampires possess a supernatural venom carried through their fangs and can consciously choose whether to release it when biting. Ordinary feeding therefore carries no risk of accidental transformation.
When venom is deliberately injected, it begins altering the human body. The victim becomes increasingly ill and may experience fever, pain, extreme thirst, heightened senses, weakness, and sensitivity to light.
To complete the transformation, the infected human must drink the blood of the vampire responsible for the bite.
If they drink the vampire's blood, the transformation is completed and they become a vampire.
If they refuse or are unable to drink it, the venom continues attacking the body. Smaller exposures may eventually be survived, but a sufficiently strong dose can result in death.
Rosewick's vampires belong primarily to three established bloodlines: Monroe, Sinclair, and Everett.
Members of each family do not necessarily share biological ancestry. Their family name represents their supernatural lineage. Every vampire belonging to a particular house ultimately descends through turning from the same original sire.
This creates a supernatural sire bond between members of the same bloodline, strongest between a vampire and the individual who directly turned them. The bond creates an instinctive awareness, attachment, and heightened emotional connection, but it does not remove free will or force obedience.
Direct sunlight burns vampires. Initial exposure causes intense pain and rapidly developing burns; prolonged exposure causes severe bodily destruction and eventually death.
Rosewick's vampires survive daylight through daylight rings enchanted by witches. The ring protects its wearer from sunlight but does not remove any other vampire weaknesses.
Only witchcraft can create or enchant these rings. Vampires therefore depend upon witches for one of the greatest freedoms they possess: the ability to walk beneath the sun.
Vampires can be permanently killed through prolonged direct sunlight without a daylight ring, decapitation, complete burning, sufficiently catastrophic destruction of the heart, or lethal wounds inflicted with silver.
Silver bullets and silver blades are particularly dangerous because silver interferes with supernatural healing. Religious objects possess no inherent power over vampires; a silver cross can harm one because it is made of silver, not because it is sacred.
Garlic has no effect. Vampires have reflections and can freely enter homes without invitation.
A stake through the heart is lethal only when carved from a particular ancient species of tree connected to the First Severance. Ordinary wooden stakes do not kill vampires. The same tree is dangerous to all descendants of the Four, though the reason has been lost to history.
Above all, vampires remain predators regardless of personality. They are capable of friendship, loyalty, love, romance, tenderness, jealousy, obsession, cruelty, and genuine attachment. These emotions are real, but they do not erase hunger or instinct.
A vampire can love someone deeply and still possess the capacity to kill them.
