There are two branches of Night Children, but both stem from Notte, as he was the first.
Their abilities and strengths/weaknesses vary slightly from generation to generation.
To become one of the Night Children, one needs to start out human, which means pure, unmagical Ever-Dying, human genes. An exchange of blood starts the process, but the human must lose so much blood that they’re near death.
- Initially, all “baby” vampires are insane. Their hunger – which, according to Notte, is called The Beast – takes over. New vamps usually need to be locked away for a while until they can gain control of themselves again.
- All vampires, regardless of ethnicity, have green eyes after changing. It’s been referred to as “vampire green,” and occasionally, it glows.
- Vampires can make a bite feel pleasant (to put it mildly) or painful (to understate). They can also alter memory so their victims don’t recall being bitten. These are all abilities Notte carefully monitors; he has a thing about consent.
- They can live on any mammalian blood for a while, but require human blood to stay alive. If they’re without it for too long, the Beast takes over again; and if they still can’t get human blood, eventually, they die.
- The blood itself can be health or not; human pathogens have no effect on vampires. However, and this is crucial, the blood must be from a living person. Even blood that has been donated is fine, but if the donor dies, or the person being drunk from dies, the blood becomes poisonous.
- They can all perform an ability they call “going to dust,” in which their physical forms disintegrate into what looks like dust motes, like the kind one might spot floating in a beam of moonlight. Whatever this form is, it isn’t dust. They can enter and exit even air-proofed containers in this form. However, they can’t attack; while no physical barriers can stop them, they can’t affect the physical world, either.
- Night Children have a special relationship with the wind, largely because the wind itself seems to view Notte as a friend. They say the wind tells him things – things no one else could possibly know.
- Vampires do not age. When turned, that is their physical age forever.
- They DO have a heartbeat, but it is very slow.
- They seem to have no limit to the blood they can drink, which is deeply confusing. So far, science has failed to reveal just where all the blood goes when swallowed.
- Vampires do not need a full physical form to function. While removing (or damaging) the head can kill them, it’s not a guarantee. Loss of limbs or organs or even much of the torso is no guarantee of death, either. If the vampire is able to go to dust, they will heal.
- Wood is their primary weakness. It enters their system, burns, damages, and prevents healing. If there’s too much wood in a vampire’s body, they can’t even go to dust.
- Sunlight only affects vampires far down the bloodline from Notte. Usually, around the fourth generation, sunburns make an appearance. By the time we reach the tenth generation, vampires must avoid the bright sunlight or face burns.
- Any blood will do in a pinch, but the Night Children need human blood. They were designed to drink it, and when deprived of it – even if given other blood – they will eventually lose control of the Beast and rip through whatever stands between them and human blood. (Fortunately, that blood-thirsty madness takes a while to form.)
Notte’s children follow specific rules. He forbids random hunting; there are no mad monster vampires running around on his watch. He also forbids his children from turning anyone they wish, instead choosing to approve each and every human his children want to bring into the fold. Most of the time, he says no.
Ravena runs her own family differently. She has to abide by Notte’s rules to some extent, but he gives her a lot of freedom – some say too much. Let’s just say her branch of the family is responsible for much vampire media and mythology throughout the world.
Self-control is the most important aspect of a Night Child’s life. Because of this, the early years of vampirism are carefully and strictly controlled, down to the clothing they’re allowed to wear.
They almost never complain about it. They feel the Beast, and with very few exceptions, are well aware they need his help to keep themselves in control.
