A werewolf is a human being who, upon the complete rising of the full moon, becomes a fearsome and deadly near-wolf. This condition is caused by infection with lycanthropy, also known as werewolfry. If a werewolf is in human form and bites the victim, they will merely gain lupine tendencies such as a fondness for rare meat.
A mixture of powdered silver and dittany applied to a fresh bite will seal the wound and allow the victim to live, but forever branded as a werewolf. The Wolfsbane Potion, invented by Damocles, allows the werewolf to keep their human mind during transformation.
Werewolves generally reproduce by attacking non-werewolves. The stigma surrounding werewolves has been so extreme for centuries that very few have married and had children. However, where werewolves have married human partners, there has been no sign of their lycanthropy being passed to their offspring.
One curious feature of the condition is that if two werewolves meet and mate at the full moon (a highly unlikely contingency which is known to have occurred only twice) the result of the mating will be wolf cubs which resemble true wolves in everything except their abnormally high intelligence. They are not more aggressive than normal wolves and do not single out humans for attack.
