Mythology
 
Werewolf
 Folklore tells of unfortunate individuals who become possessed by the spirits of
 animals, doomed to change uncontrollably into the beast that inhabits them. The
 wolfman or werewolf is the most common, but other variations exist. In India and
 China, for instance, Rakhasa, or weretigers are thought to prey on unsuspecting
 victims. Animal possession is a common theme in many cultures, including some
 Native American and African tribes. The traditional lore regarding werewolves holds that
 they change on or about the full moon, and that a silver bullet is the only weapon
 capable of killing them. Other werebeasts are rumored to have the ability to change
 form at will, and some can be exorcised using rituals and magic. It is thought that
 legends involving werebeasts were partially based on a rare disease called
 Lycanthropy, a syndrome causing the victim to grow hair over the entire body and
 making the eyes hypersensitive to light. Sufferers of this disease rarely went outside in
 the daylight, due to their startling appearance and the fact that sunlight was painful to
 their eyes.

Frankenstein
 The idea of re-animating the dead has existed for centuries. The most famous legend
 regarding this concept was that of Baron von Frankenstein's Monster, from a story by
 Mary Shelley. As the story goes, Victor Frankenstein, a brilliant young doctor, solved
 the eternal riddle of life and creating a being from body parts he scavenged from
 corpses. His creation was to be a superhuman, with great physical prowess and
 extreme intelligence, but something went very wrong. Faced with the reality that he
 was unlike anyone else in the world, Frankenstein's monster demanded a partner be
 created for him. When Frankenstein failed, the monster vowed to haunt his creator as
 revenge for the hell that was his own life.

Witchcraft
 Believed to be in league with Satan and practitioners of the black arts, witches were
 often totured and killed for their alleged crimes. It was widely held that witches could
 hex their enemies using a variety of spells and amulets, causing sickness and injury.
 Often what seemed to be a run of bad luck or a persistent illness was thought to be
 the work of witchcraft.

Demon
 Demons are said to come in many shapes and sizes. They fly, change shape, shoot
 fire from their mouths, and generally plague humanity for their own amusement.
 Certain mythology traces the origin of demons back to a time before history, when the
 world was not controlled by mankind. The "Ancient Ones" as they are sometimes
 called, ruled the Earth and all its beings for eons, superpowerful and bloodthirsty.
 Banished into the lower realms, they do everything within their power to corrupt the
 world, sometimes managing to walk the Earth inside human bodies, "possessing"
 them. It is said that by knowing a demons true name and calling it out in ritual, you
 can summon it. Protected inside the magical barrier of a pentagram or five-pointed
 star, a strong sorcerer could force a demon to do his bidding. Underestimating one's
 magical ability was, however, a fatal mistake. If one lost control of a demon after
 summoning, one would usually die and lose one's soul for all eternity. Demon's are
 notorious liars and masters of trickery. Lured into a dialogue with the demon, an
 unwary individual could be fooled into acting as the demon's servant, only to be
 sacrificed when the demon grew bored or found a better follower.
