Vampires are descended from a loose society of witches, sorcerers, and conjurers in 11th century Europe. Information and rituals were shared amongst the group, and after one such ritual was circulated, members began to notice a strange affliction that slowly started to make their lives miserable. After several months, desperate for a cure, they met in Venice to attempt to cure the affliction. They all participated in a particularly difficult demonic summoning. While the demon could not undo the curse that had been placed upon them, it could ease the symptoms, allowing them to sate their hunger and thirst with the blood of humans, and giving them the strength and lasting health to enact the revenge that they wanted for their predicament, in exchange for their souls, and the souls of all of the children they might have. They agreed, and the first vampires were created.
A vampire's curse can be transmitted two ways, by birth and by blood. All of a vampire's children will be vampires themselves, regardless of the status of their second parent. It takes only one drop of of a vampire's blood entering the body in order for a normal human body to begin the transition to vampire.
Physically, there is little difference between the two types of vampires.
1. Physical Strength: Both are strong enough to bend a metal pipe or jump to the top of a two story building.
2. Speed: Vampires have reflexes twice as fast as humans, and are able to move at speeds up to seventy miles an hour.
3. Longevity: Most born vampires stop aging between the ages of 20-30, as the body completes the gradual change to vampire.
4. Healing: A vampire's body heals injury twice as fast as a human. Save fire, the sun, and decapitation, most injuries will not kill a vampire, though they can and do slow them down or even put them into a torpor-like state. When in a torpor, the vampire's metabolism slows down, preserving the blood in the body to be used for healing and sating hunger. Still, most of the time, a vampire will wake up from a torpor ravenous.
5. Most possess a natural aptitude for magic, though knowledge of magic is not innate and must be taught. Personal belief can affect this, with those who do not believe in magic showing little to no sensitivity.
6. Most vampires possess hunting and killing instincts to aid in getting the blood they need.
7. Senses: Eyesight, especially night sight, is considerably increased. Hearing is sensitive enough to hear their prey's heartbeat in a quiet room. Sense of smell is slightly more sensitive, to the degree of an exceptional human.
The weaknesses each type of vampire possesses vary based on how they were made. Vampires by birth show different weaknesses than those made by blood.
1. Vampires typically do not begin to change until they reach puberty. They do not reach their full strength and resilience until their mid-to-late 20s. Before the change, they are subject to all the same injuries, diseases, and aging as normal humanity.
2. Vampires by birth usually have red eyes, and even as children are often photosensitive.
3. As children, vampires tend to sunburn easily. Once they've gone through the change, vampires by birth are the group most affected by the sun. They cannot stand even indirect sunlight or they will burst into flame.
4. The perpetual hunger and thirst that afflicts most vampires does not usually affect a vampire's children until they begin puberty, but can under rare circumstances manifest in younger children. Younger children affected by this hunger are unable to eat or drink normally, and are required to drink blood, as their elders do. Vampires by birth are usually more affected by this hunger and thirst than those made by blood. While a vampire made by blood can be sated, a born vampire very often is not. Control is learned early in life, as vampire children are attracted to blood at an early age, before the hunger and thirst take hold.
5. Born vampires are born with the same instincts their elders use for hunting. They also usually are born less able to empathize with others and with a strong possessive instinct. All born vampires are extremely territorial, and it is not uncommon to find families returning year after year to the same ancestral home.
6. Born vampires have a hard time conceiving, as the body usually rejects the fertilized egg, and it typically takes many years before a child comes to term successfully.
In contrast, vampires made with blood show other traits.
1. They are frozen at the age in which they were given blood, regardless of age. The change, for this group, takes typically two years, in which the fledgling vampire will be more ravenous than at any other point later in life.
2. Their eyes usually do not change color, and remain the same color they were in life. They are usually not as photosensitive as born vampires.
3. Once fully changed, they are not as sensitive to sunlight as born vampires. They can stand indirect sunlight for minutes at a time with blisters and peeling to show for it.
4. Though they feel the same hunger and thirst as born vampires, it is not quite as overwhelming, and can be sated by feeding regularly. Control is not quite as important to learn, for this group, and many do not show the same restraint as born vampires when in the presence of blood.
5. Though they acquire the same hunting and killing instincts as born vampires, they are still subject to the same emotions they had as humans. While born vampires rarely feel love, empathy, or guilt, made vampires often do.
6. Most made vampires do not feel the same territorial instincts as born vampires, and they often wander.
7. Fertility is reduced dramatically in made vampires, and it is not uncommon for women turned into vampires to be unable to conceive at all.
Both groups are subject to some of the same weaknesses.
1. Food: Holds no nutritional value for vampires who have completed the change. It tastes disgusting to them, and most find even the smell nausiating.
2. Water: Pure water is a poison when ingested, accidentally or otherwise. Depending on degree of ingestion, symptoms range from vomiting, dizziness, weakness, to torpor or death.
3. Hunger: Vampires are perpetually hungry and thirsty and must drink human blood to satisfy those cravings. Born vampires typically require more blood than made vampires.
4. Sunlight: No vampire can stand in direct sunlight and live. Direct sunlight ignites vampiric flesh upon contact. Indirect sunlight causes severe burns on made vampires, and it can ignite born vampires.
5. Fire: Both types of vampire are equally combustible, and avoid fire. Their flesh burns readily and is difficult to put out, once it's alight.
6. Wooden stakes: A wooden stake through the heart will disrupt the demonic pact, taking the vampire's strength and health. It will make it impossible for a vampire to feed while leaving the hunger and thirst. While it will not kill a vampire, the vampire will very quickly waste away into a living mummy, remaining unable to move and feed until the stake is removed.
7. Decapitation: A vampire will die when its head is removed.
8. Crosses: A blessed cross will burn a vampire's skin. Most crosses and crucifixes will make as vampire feel weak and sickened.
9. Mirrors: A vampire's reflection doesn't show in a mirror.
