Magical Creatures

Creation

Vampires are created by draining the blood completely from an intended victim, then performing a powerful magical ritual in order to raise the body from its state of quasi-death.

Human women are capable of giving birth to a vampire's baby - this results in a half vampire.

Vampire women are incapable of giving birth. Samantha Burns is the only known exception to this, leading many to believe that it was due to her being turned while already pregnant. New studies are being launched to validate these theories.

Feeding Habits

When a vampire feeds, they use a special mix of chemicals in the saliva and magic to make the victim feel immense pleasure. This is used by vampires to secure continued donors for blood.

Vampires cannot drink the blood of animals - however, there are a variety of expensive, foul tasting, and not very nutritious synthetic blood potions available for the "pacifist vampire".

Most vampires enjoy the taste of blood, leading to magical sweet shops selling blood flavored candy.

Hogwarts provides its vampire students with a daily helping of donated blood from St. Mungos - however, it is just enough to survive. The school lacks the funds for much more.

Lifestyle

The more recently a vampire has fed, the more powerful they are. A well fed vampire is noticeably - but not significantly - faster, stronger, and tougher than a very athletic human. At their thirstiest, a vampire is noticeably - but not significantly - weaker than a very unathletic human.

Sunlight hurts vampires. By using a special potion (which may be obtained from a qualified potioneer) they can spend a few hours in the sun each day. Any more than that and they begin to weaken before quickly dying.

Vampires are pale unless employing some kind of magical tanning. The whites of their eyes become yellow, but the irises stay the same color as when they were turned.

Vampires do sleep, but do not eat or go to the bathroom. They can be seen in mirrors, but are warded off by garlic. Religious symbols are iffy - their affect varies from individual to individual.

Vampires often feel a strong association with bats. Most vampires have a bat patronus or animagus.

Half vampires are almost entirely like normal humans. They are usually more sensitive to the sun and often are rather gifted athletically. Almost all have an intense allergy to garlic.

Creation

Werewolves are technically not magical creatures. Rather, they are humans suffering the blood borne disease of lycanthropy.

Lycanthropy can be transmitted in the following ways:

• The bite of a fully transformed werewolf.
  
• Intercourse without a condom with someone who has lycanthropy
  
• Sharing needles or syringes with someone who has lycanthropy
  
• Being deeply punctured with a needle or surgical instrument which has been contaminated by the lycanthrope virus
  
• Getting infected blood, semen or vaginal secretions into open wounds or sores.

People are not generally born with lycanthropy. Female werewolves cannot have children themselves as shapeshifting once a month causes miscarriage.

If a couple are able to find a willing surrogate, the chances of either the child or surrogate catching the disease is negligible, provided the procedure is performed by a qualified professional.

Lifestyle

Werewolves are completely wolf under the light of the full moon, and completely human when not.

Werewolves do not have a heightened sense of smell or hearing when in human form, no matter what they tell you.

Werewolves do not form packs, unless they have been forced into an unnatural social order by some maniac like Fenrir Greyback.

In order to be legal citizens in Britain, werewolves must register themselves with the Ministry of Magic and abide by Werewolf Regulations.

Werewolf regulations include either having (and using) a regular supply of wolfsbane potion or being locked up during the full moon.

A werewolf not on wolfsbane potion is insane. They will indiscriminately attack and kill anything, and if nothing is available, they will attack themselves.
