the presence of the blood is likely to have made him fevered and hot to the touch. This process is, however, much better than the alternative.
Even a small amount of vampire blood consumed may require the consumption of quite a lot of holy water. This is a case where it is better to be safe and consume too much holy water than too little. The victim can be assumed to be healthy and cured when the consumption of holy water no longer produces the emetic response.
SUBJUGATES
Powerful vampires will often decide that, rather than feeding haphazardly on whatever blood they can find, they would prefer a ready supply. They will then create a vampire subjugate: They will select a victim and keep him close by, drinking from him and also feeding him small amounts of vampire blood. This vampire blood will make the subjugate docile, obedient, and, in time, worshipful of his vampire master. The subjugate will cease eating food and will survive entirely on a mix of animal blood and vampire blood. He will not become a full vampire, but subjugates are kept in a suspended animation, their aging process drastically slowed (although they are not immortal and will eventually die).
A subjugate who is turned into a vampire loses his obedient and worshipful nature and becomes a normal vampire, like any other.
Most subjugates are young in appearance; vampires revere youth and beauty and tend to prefer their subjugates to possess both. (A practical consideration is also present. The younger the subjugate, the less chance that he will turn out to have diseased or otherwise problematic blood.)
Subjugates are sometimes known as darklings. Although the term is archaic, it is still used in some formal vampire rituals today. Vampires love nothing so much as formal rituals.
The culture of subjugates among vampires is that, first, they are no longer human but are something else, and therefore are not afforded the rights and respect granted to humans. Subjugation is in essence voluntary slavery; subjugates effectively consent to become the property of their vampire masters, renounce their human names, and so on. A subjugate would never introduce himself to another vampire or another subjugate, for instance; it would be his master’s choice whether to communicate his name, or indeed, whether the subjugate would possess an identifying name at all.
The creation of new subjugates was made illegal in the Seventh Accords of 1962. Vampires who had subjugates created prior to the Accords were allowed to keep them. The Law also continues to allow vampires to transfer existing subjugates to other vampires. These two facts have made it almost impossible to convict vampires for creating subjugates. Vampires simply claim that their subjugates predate the Accords, and since the subjugates’ identities and lives are tracked by the vampires themselves, it is very hard to prove otherwise.
FLEDGLINGS
    Note: did not read. Too soon.
A human who has consumed enough vampire blood to be themselves transformed into a vampire does not, as some popular mundane stories would have it, abruptly turn from a living human in one moment to a vampire in the next. The human—who is known in vampire culture as a “fledgling”—must die, be buried, and, in being reborn, make his way out of his grave of his own power. (In the rare and sad case that a Shadowhunter is irreversibly turned into a vampire, this is the one circumstance in which her body may be buried rather than burned.)
Like a ghost, a fledgling rising from his grave draws energy and strength from the living things nearby, drawing their heat and producing a distinctive cold spot around his grave. When he has risen, he will be nearly feral and starving for the blood that will, for eternity, sustain him. This is why fledglings are the most dangerous of vampires. Sometimes a vampire clan will turn a human to a vampire purposefully, and in those cases the transition usually goes smoothly. The clan can be present for the vampire’s
