Werewolves
Chapter 12
A werewolf, also known as a lycanthrope, is a human being who, upon the complete rising of the full moon, becomes an uncontrollable, fearsome and deadly wolf. This condition is caused by infection with lycanthropy, also known as werewolfry. Werewolves appear in the form of a wolf but, there are distinctions between them and regular wolves.
A mixture of powdered silver and dittany applied to a fresh bite will seal the wound and allow the victim to live on as a werewolf, although tragic tales are told of knowing victims begging for death rather than becoming werewolves. The Wolfsbane Potion, invented by Damocles, allows the werewolf to keep their human mind during transformation.
A werewolf cannot choose whether or not to transform and will no longer remember who they are and would kill even their best friend given the opportunity once transformed. Despite this, they are able to recall everything they have experienced throughout their transformation upon reverting to their human form.
The monthly transformation of a werewolf is extremely painful if untreated and is usually preceded and succeeded by a few days of pallor and ill health. The werewolf may display irritation towards friends.[3] While in his or her wolfish form, the werewolf loses entirely its human sense of right or wrong. However, it is incorrect to state (as some authorities have, notably Professor Emerett Picardy in his book Lupine Lawlessness: Why Lycanthropes Don’t Deserve to Live) that they suffer from a permanent loss of moral sense.
While human, the werewolf may be as good or kind as the next person. Alternatively, they may be dangerous even while human, as in the case of Fenrir Greyback, who attempts to bite and maim as a man and keeps his nails sharpened into claw-like points for the purpose. Though werewolves usually only infect their victims through biting, they sometimes take it too far and kill their victims.
Without any humans nearby to attack, or other animals to occupy it, the werewolf will attack itself out of frustration. This leaves many werewolves such as Remus Lupin with self-inflicted scars and premature ageing from the difficult transformations.
Werewolves can be easily distinguished from regular wolves by their shorter snout, more human-like eyes, the tufted tail, and their mindless hunting of humans whilst in wolf form.[3] At all other times, they appear as normal humans, although they will age prematurely, and will gain a pallor as the moon approaches and then wanes.[3]
The real difference between a wolf and a werewolf is in behaviour. Genuine wolves are not very aggressive, and the vast number of folk tales representing them as mindless predators are now believed by wizarding authorities to refer to werewolves, not true wolves. A wolf is unlikely to attack a human except under exceptional circumstances. The werewolf, however, targets humans almost exclusively and poses very little danger to any other creature.
