Let me say first that the following is about these Fae in their original state, when they are completely true to their soul. This is how it was before the need to hide became so great and all otherkin took to hiding in human form.
Beansidhe: Originated in Ireland, but faeries who are announcing death are found worldwide. She is also part of other Celtic lore, but is most strongly tied to Ireland. The Beansidhe is also known as Washer of the Shrouds, Banshee (the Anglicized spelling), Cointeach (literally "one who keens"), Cyoerraeth, Gwrach y Rhibyn, and Cunnere Noe.
Her element is water and she appears at night before a death. She is a well known and much feared faery, and sometimes classified as a ghost. She is female and appears in a filmy, full-sized human form with long stringy hair partially covered with a hood, and a whit gown or shroud, and has a wet ghost like appearance. Her keening (mourning wail) is heard at night prior to death and many believe her to be attached to only the old noble families of Ireland, those of Milesian decent.
Bean-Tighe: Originated in Ireland and is also called Our Housekeeper. Their element is earth and they are found at hearthsides, especially between Samhain to Beltane. Pronounced Ban-tee or Ban-Teeg; no one has ever fully described them. They are thought to appear as small elderly women in old-fashioned peasant clothing with kindly, dimpled faces. They are very friendly to humans and wish to have a friendly human house to watch over. They are faery housekeepers who can be found watching over children, hearths, and pets. It is also believed they would finish up chores left undone by the tired mother of the house. They love fresh strawberries and cream.
Brownies: Come out at night to finish work that's been left unfinished. They are devoted to their household and expect nothing but a bowl of cream and a cake for their concern. Any offer of reward or clothing will drive the brownie away. Boggarts are "evil" brownies, they've often have been wronged by humans. They like tricking humans and often cause a great deal of trouble.
Dinnshenchas: Originated in Ireland. Their element is fire and they are found in pastures or at shrines to Aine which are found in her home county Kilkenny. Pronounced Din-sheen-k'has, they are dwarf fairies in the service of the Irish Goddess Aine, who is a cattle goddess and a protector of women. They can shape shift and guard cattle and avenge women harmed by men.
Dwarf: Although the Scandinavian dwarf is often associated with faeries and elves. Dwarves are not generally regarded as a faerie race. The Duegar tales from Scotland and northern England of evil dwarves who harry travellers and construct elaborate and deadly traps, are likely a blend of imported tales of dwarves and local legends of trickster faeries. Dwarves live underground partly because they like to be close to the metals that they love, but mostly to avoid sunlight, which turns them to stone, or in some legends, into toads. The legendary powers of dwarven metal smiths are magical in nature. Some of the most powerful artefacts of the gods were made by dwarves, such as the Ring of Odin, and the sword Excalibur. Dwarves are also rumoured to have strong prophetic abilities. It is said that the aged appearance of dwarves is because they are mature at age 4 and grow a beard by age 6. Standing slightly shorter than humans, they wear long clothes and keep their beard long as well. The purpose of this is to help hide any deformity which the dwarf might be self-conscious about. Many dwarves have misshapen feet.
Dryad: In Greek mythology a Dryad is a nymph of the trees and forests. In early legend, each dryad was born with a certain tree over which she watched. She lived either in the tree (in which case she was called a hamadryad) or near it. Because the dryad died when her tree fell, the gods often punished anyone who destroyed a tree. The word dryad has also been used in a general sense for nymphs living in the forest.
Elves: Originating in Scandinavia in Germanic Mythology elves are a type of fae, usually represented as tiny people. They are said to dwell in forests, in the sea, and in the air. Although they can be friendly to man, they are more frequently vengeful and mischievous.
Formorians: They originated in Ireland and are also called The Formors. Their element is water and they are found at sea shores at night. They are sea monsters, the survivors of a banished faery race that was driven out of Ireland by the Tuatha De Danann. They have bizarrely misshapen bodies. They do have arms and l*** and have been occasionally seen on land. They are very stupid and ill-tempered.
Geancanach: Originated in Ireland and the Hebrides Islands of Scotland. Their element is fire and they are most active at night, and can be found around a blazing fire at your hearthside. Pronounced Gan-cahn-ock, they are always depicted as being very small, and having playful, mischievous smiles. They are pixie-like in appearance and have huge eyes that curve upward on the ends and large pointed ears. They have small wings, but they do not seem to be functional, and appear to dematerialize and reappear quickly to move from place to place. They are often mistaken for flickering lights or lighting bugs.
They are guardians of the home and hearth and crave the warmth of the fireside and are harmless. They do have a tendency to play pranks though. Any kindness from them can be repaid with the warmth of your fire and fresh milk.
Goblins: Originated in Greece. The word goblin is derived from the Greek "kobalos" meaning rogue. Goblins are known as the thieves and villains of the fae realm. The term goblin can apply either to the ugliest members of the fae, or to certain sub-races. Some reside in mines where they search for the earth's treasures. Human miners take the resulting sounds as a sign of good luck, believing the present ore to be of high value.
Other goblins choose human residences where their mischief includes the banging of pots and pans, rearranging furniture, removing the clothes from sleeping humans and knocking on doors and walls. Still others of the family prefer grottos, often residing in the same one for their entire life. Those fae numbered among the goblin sub races, include: Scottish Trows, Scandinavian Trolls, English Spriggans, Welsh Knockers, Cornish Knockers, German Kobolds, the Irish Phooka and even Shakespeare's infamous Puck are all considered goblins.
Gnomes: One of the most well known, and documented faeries of the forest. Many years ago, some Gnomes were even found working inside the houses of Humans, but this was usually a mutual agreement, because the Gnome, being as quick, strong, and smart as he is could escape at any moment. The Gnome is usually 15 cm tall, but with its cap on it appears much taller. Their feet are somewhat pigeon toed which gives them an extra edge on speed and agility through the wood and grass. The Gnome really has no great enemy accept the troll, which he can easily outsmart. Most Gnomes are 7 times stronger than a man, can run at speeds of 35 miles per hour, and have better sight than a hawk.
These abilities help the Gnome to do many things, such as find wounded, dying animals for which they feel they are responsible for. Because of their love for animals, all the animals of the forest are the Gnome's friends and are willing to help him at any time. If you see a Gnome, he might very well be riding on the back of a fox, flying with a hawk, or even riding on the back of a frog!.
Lesidhe: Originated in Ireland and India. They are known as Leshes in Slavic lands and Suibotschniks in Russia, and Leshiye in Germany. Their element is air and they can be found in wild woods. Pronounced Lay-shee, they are guardians of forests who are always disguised as foliages. They are usually found in groups, and seem to be androgynous.
They are classified as solitaries rather than trooping faeries, because they seem to have little to do with each other. They are active in the spring and summer, especially at dawn and dusk, but seem to prefer being nocturnal. It is believed they have come to dislike human for their careless treatment of the environment. Though they have never harmed anyone, their nasty pranks usually involve trying to lose people in deep woods.
Leprechaun: Originating in Ireland the Leprechaun is an Irish fairy. He looks like a small, old man (about 2 feet tall), often dressed like a shoemaker, with a ****ed hat and a leather apron. According to legend, leprechauns are aloof and unfriendly, live alone, and pass the time making shoes. Leprechauns are the self-appointed guardians of ancient treasure that was left by the Danes when they moved through Ireland. The leprechauns hide their treasure in crocks or pots. If caught by a human, he will promise great wealth if allowed to go free. Treasure hunters can often track down a leprechaun by the sound of his shoemaker's hammer. If caught, he can be forced, with the threat of bodily harm, to reveal his treasure, but the captor must keep his eyes on him at all times. If the captor's eyes leave the leprechaun (and he often tricks them into looking away), he vanishes and all hopes of finding the treasure are lost. A Leprechaun carries two leather pouches. In one is a silver shilling, a magical coin that returns to his purse each time it is paid out. In the other pouch, he carries a bright gold coin. This coin turns to leaves or ashes once the Leprechaun has parted with it!
Los Aluxes: Originated in Mexico. Tiny Mayan gnomes who help the country folk look after their crops. Even today, farmers leave out gifts, food and drink for the Aluxes as a sign of gratitude for their help when the harvest is over. If they do not leave these offerings, they say they hear laughter, their tools disappear and their crops are stoned.
Pixies: Originated in Scotland and are a small, winged type of fae with foxglove or toadstool hats (their sacred plants) that abide in the joys of living, and very seldom play tricks on anyone but those who are mean to them. They dislike laziness, but they adore music and dancing especially when they can see their reflections. Since fine china is an excellent mirror, pixies are often accused of breaking dishes. They are also blamed for the odd sounds a house makes at night, and for causing doors to stick when the weather turns damp.
Sprites: Origin is unknown, they are the more playful nature spirits, and are not likely to inhabit anything but trees, a pond, or any other place that's serene and cool. They are often found playing with nymphs, or tormenting butterflies. Sprites were charged with changing the colours of the leaves on the trees in autumn. Each one comes fully equipped with bright orange & yellow paints and several paint b****** to make sure their job is done properly. Sprites are also some of the most creative of the fae... being muses to artists and poets. Sometimes they even decide to bond themselves to a human or elves and stay with them their entire lives; sometimes these Sprites even follow their bonded into the Otherworld.
Sylphs: The sylphs are the air spirits. Their element has the highest vibratory rate of the four (air, earth, fire, water). They live hundreds of years, often reaching one thousand and never seeming to get old. They are said to live on the tops of mountains. The leader of the sylphs is a being called Paralda who is said to dwell on the highest mountain of Earth. Sylphs often assume human form but only for short periods of time. They vary in size from being as large as a human to being much smaller. They are volatile and changeable. The winds are their particular vehicle. They work through the gases and ethers of the Earth and are kindly toward humans. They are usually seen with wings, looking like cherubs or fairies. Because of their connection to air, which is associated with the mental aspect, one of their functions is to help humans receive inspiration. The sylphs are drawn to those who use their minds, particularly those on creative arts. Sylphs are very regal in manner and bearing. Theirs is an ancient and proud legacy, and it is dying out. It is for this reason that they have come down off their mountains and rejoined changeling society in large numbers. If they are to die, then at least they will be remembered for the honour, glory and majesty that is inherent to their kind. Sylphs are loners, content to soar the skies with the eagles. They care little for the machinations and politics of "ground folk", and they rarely interfere with changeling society. Rarely do they associate with others, but when they do, they usually form bonds that last for life. Sylphs hold their word of honour to be inviolate, and once sworn to protect something, they will defend it to (or even past) their death.
