Fey

Fey are the creatures from the Feywild, a parallel plane to the Material Plane. They are strongly magical and some of them are even immortal.

Types of fey
Aside from the immortal, immutable Archfey, most fey live for upward of 300 years, and they change forms (including gender) based on their innermost feelings, so that the most unstable of fey can wildly change their type almost a dozen times over the course of their lives. Two fey can have children of different types than themselves.
 * Various hags, including the sea fury
 * Quickling - An extremely fast-moving fey that looks like a lithe, hairless elf-goblin hybrid with dull grey skin and mostly white eyes with a faint pupil.
 * Dryad/nymph
 * Satyr/faun - Appearing like a human with the horns of a goat or ram (and sometimes the ears to match) and a furred lower body supported by two cloven-hooved legs.
 * Sprite
 * Pixie - In the case of the Wisher pixies, they are tiny, lithe, winged fey who wear leaf- or vine-based clothes and cast spells.
 * Blink dog - Appears like a dog with unusually angular limbs and abnormally long, pointed ears, but is about as intelligent as an average humanoid and can teleport short distances.
 * Familiars - Some wizards summon fey familiars. Familiars can take the form of a variety of tiny beasts.

The common language of most fey is Sylvan.

Related races
Both elves and firbolgs are related to the fey. Forest gnomes are also believed to be related. Some creation myths of the centaurs and orcs claim they originated as elves.

Firbolg warlocks make pacts with powerful fey.

History
The elven god Corellon is the patron of the fey.

During the Age of Arcanum, Aeorian hunters were created to be able to take on, among others, fey entities.

Following the Calamity, the balor-turned-fey Naviask was drawn to Exandria to heal its scarred lands.

Shortly after 445 PD or so, the Ki'Nau of elven heritage paid respects to the fey beings of the Doralle Woods at the base of the Cyrios Mountains before founding the city of Gwardan. As of 836 PD, fey beings still protected those woods.

Sometime between 488 and 523 PD, Zan Tal'Dorei used the ambient, illusionary fey magic of the Verdant Expanse to her advantage, ambushing Neminar Drassig's forces and killing him.

The elves of Molaesmyr placed powerful fey enchantments throughout the Veluthil Forest for protection, but in 585 PD a recovered Aeorian artifact caused a powerful wave of corruption to burst forth from the city, twisting many of the elves into mad fey abominations.

Campaign One: Vox Machina
In 809 PD, when Grog Strongjaw was suffering from the effects of Drath Mephruhn trying to place his phylactery in Grog's chest, the party was tasked with collecting the heart of a nymph, which is how the party came to be acquainted with Nahla. In 811 PD, Vox Machina naturally encountered a variety of fey when traversing the Feywild to acquire the legendary bow Fenthras, one of the Vestiges of Divergence. The association they made with Artagan proved to be critical the next year, when they needed to retreat to the Feywild before their final battle with Vecna, and the party repaid the Archfey by building a doorway through which he could travel to the Material Plane.

Campaign Two: The Mighty Nein
Artagan played a major, ongoing role in the life of Jester Lavorre, a cleric of the Mighty Nein. The hag Isharnai played a key part in the origin stories of both Beauregard Lionett and Nott.

In 835 PD, the Mighty Nein encountered Dashilla the Dreadful when seeking out the wreckage of the Tide's Breath.

Reani said some fey were responsible for giving her druid powers.

Exandria Unlimited
The faun Fearne Calloway is one of the members of the Crown Keepers, and her relationship to her grandmother Morri and the Feywild drew the party to the attention of Myr'atta Niselor, the main antagonist of their adventures into the Rifenmist Jungle.

Tal'Dorei
As of 812 PD, a host of benevolent fey makes its home in the Frostweald due to some "Great Shadow" that threatens their home in the Feywild; they are displeased with the presence of the massive Shivergut tribe of orcs that also resides in the forest. A nymph named Arethusa guards three pools that serve as portals to three different Archfey's forests in the Feywild. The deeper areas of the Torian Forest are inhabited by a sect of displaced fey, trusting neither the humans nor the dwarves who collect wood for Emon's timber and Kraghammer's firewood.

The elves of Syngorn open small doorways to the Feywild in warded spaces on Elvendawn to celebrate with fey. When Syngorn retreated into the Feywild during the Chroma Crisis, Artagan helped a number of fey, including a pixie prince named Windybranch, slip past the city's wards and take up residence in Il'shavfa Manor, where they proved incredibly difficult to dislodge.

Deep in the western part of the Verdant Expanse is the Mirescar, an ancient and particularly dense part of the forest that is corrupted by some darkness, leading to the creation of fey abominations. The adventure hook A Sickness Spreads in the original Tal'Dorei Campaign Setting sourcebook, set in 812 PD, involves the spread of that corruption and the appearance of new threats emerging from the Mirescar.

Wildemount
As of 836 PD, fey entities are sprinkled in wild areas all around Wildemount. Mischievous fey sometimes mingle with the people of Charis in the moonlight. Pixies and hungry fey spirits also wander the Cyrengreen Forest, interfering with overly greedy loggers, and a small society of fey folk lives in an enchanted forest on the isle of Vide Cay; a faerie witch interferes with Revelry captains who try to use the island. Molaesmyr is still haunted by all manner of terrible fey, including green hags and their minions, who kidnap children from Shadycreek Run for the hags' dark rituals. The Tooth of Zehir in Blightshore is said to be home to exotic fey creatures.

Like the elves of Syngorn, the elves of Bysaes Tyl open small doors to the Feywild on Elvendawn.
