Note: This isn't a list of every race, just a few of them to help flesh out the established universe.
Zombie: A human who has been reanimated from death, through means of necromancy or science. They are constantly hungry, and though they have cravings for the flesh of the living, many manage to lead productive lives by suppressing their urges with meat-based diets. Most prefer the term "reanimated" due to the connotations associated with "zombie".
Alien: Short and grey-skinned, little is known about our extraterrestrial neighbors other than their intelligence and affinity for hot desert climates.
Chupacabra: A Mexican variant of the Common Goblin, with a penchant for red meat. Most are about three feet tall, and resemble bipedal, hairless coyotes. They are a protected species.
Swamp Creature: A fishlike humanoid. Despite their species name, Swamp Creatures are found in freshwater and saltwater alike. However, only 4% of Swamp Creatures live outside of Louisiana.
Ghost: The soul of a deceased human who has unfinished business on earth. Most are harmless, though some enjoy frightening humans. Particularly vengeful or angry ghosts are known as
poltergeists, which are considerably more dangerous.
Werewolf: Technically a human with an incurable disease, werewolves are humans who turn into large bipedal wolves when in sight of a full moon.
• Werebear: A less common transformation in America, werebears are humans afflicted with a similar virus that is rarely found outside of rural Russia.
Sasquatch: A tall, apelike hominid. Originally seen as stewards of the forest, their numbers have been steadily declining for decades.
Goblin: Short, scrawny and green. They are known for stealing babies and replacing them with one of their own, which is called a
changeling.
• Gremlin: A subspecies of goblin, gremlins have instinctual urges to dismantle and hijack machinery. They are shock-resistant and secrete oil from their skin, making it difficult to capture one without a tranquilizer.
Vampire: A human who has been given vampirism. Other than a set of retractable fangs and pale skin, vampires are virtually indistinguishable from humans, and stop aging after they have been turned. Sunlight harms them, but is not instantly fatal. As undead, they are vulnerable to holy symbols.
• High Vampire: A species entirely separate from humans. They are similar in appearance to humans, though high vampires have long fangs, pointed ears, batlike facial features, and are almost always bald. They are not undead, but very long-lived, and can give humans vampirism. Humans turned by a high vampire are susceptible to mind-control by the high vampire. As high vampires are not undead, holy symbols have no effect on them, though they have allergies to garlic. Sunlight is instantly fatal to them.
Demon: In short, Demons are technically the ghosts of the exceptionally cruel and evil. They are
much more powerful than ghosts and poltergeists, and are usually dealt with by trained, professional exorcists. Usually, humans who become demons after dying follow one of the three Abrahamic religions -- Christians and Jews become demons, while Muslims become jinns.
