DICTIONARY DEFINITIONS

Lycanthropy:

At the Center of Biomedical Research in Guadalajara, Mexico geneticist Dr. Luis Figuera is studying a Mexican family with a rare genetic mutation that causes fur like hair to grow all over their bodies. This werewolf disorder has mysterious resurfaced for the first time since the middle ages. The gene that causes the mutation lay dormant for centuries. It can be passed through either parent in the "X" chromosone. This is known as the "Werewolf Disorder".

LYCANTHROPIC DISORDER :

Lycanthropic Disorder - is a mental condition in which the subject (called a Lycanthrope) believes that he or she is a werewolf. The subject does not actually change shape, but is nevertheless capable of being as dangerous as an actual werewolf. Most cases of supposed werewolfry are really the works of Lycanthropic Disorder victims.

MAN TO BEAST:

In real werewolves a physical change to wolf form does occur. The change can be voluntary (at will), or can be forced by certain cycles of the moon and certain sounds (such as howling).

WEREWOLVES & IMMORTALITY:

Werewolves are immune from aging and from most physical diseases due to the constant regeneration of their physical tissue. They can, therefore, be virtually immortal. However, they can be killed by any wound that destroys the heart or the brain, or any form of death that causes brain or heart damage (such as hanging or other oxygen-deprivation methods).

THE MIND OF A WEREWOLF :

Though primarily a true wolf while in wolf form, there is some proof that the werewolf retains enough knowledge to assist his killing; recognition of victims, evation of traps, and human cunning have all been seen on werewolf cases.

BECOMING A WEREWOLF:

There are several ways to become a werewolf. They include being givin the power of shape shifting through sorcery, being cursed by someone who you have wronged in some way (called Lycaeonia curse), being bitten by a werewolf, and being born to a werewolf. In each case, the blood becomes tainted or cursed.
...
ALPHA & BETA WEREWOLVES:

The relationship between Alpha and Beta werewolves is a complex one. Once a subject is bitten by a werewolf, his or her life and death are doomed to the werewolf curse. The victim does, however, have some hope - as long as they themselves do not taste of human blood, the curse is reversible. If the Alpha werewolf is killed - through some action of the Beta - the Beta's curse is broken. It is important to note that whether the Beta werewolf was bitten by the Alpha werewolf himself or by another Beta, it is the Alpha who must be destroyed - the source of the original tainted blood. It is also an interesting note that since Betas and Alphas share common blood, an Alpha cannot physically harm a Beta of his own bloodline by his own hans without inflicting the same injury upon himself. However, if a Beta is harmed or killed by another, it does not affect the Alpha.

SYMPTOMS OF WEREWOLFRY:

When hunting for a werewolf it is important to remember that your biggest clues will come through your suspects personalities. Becoming a werewolf is not transparent, no matter how the victim tries to hide it. The tainted, sub-human blood appearence. Therefore, look for symptoms in your human suspects that include increasing violence, increasing aggression, unprovoked rages, insomnia, restlessness, and other bizarre behavior. Unfortunately, over time these symptoms can be brought under control, so do not rely on them exclusively.
