Fang of Haynekhtnamet
The Fang of Haynekhtnamet is a literal fang which was carved into a blade and fashioned into a small dagger. It is named after Haynekhtnamet, a mythical wamasu from the Shadowfen region of Black Marsh. Scholars believe that Haynekhtnamet is not actually a single creature but a series of wamasu, and as such it's possible that there are multiple Fangs.
The most famous Fang of Haynekhtnamet was created by a score of Nords who fought Haynekhtnamet for seven days and nights before finally bringing the creature down, believing it to be a dragon. One of the survivors took a fang as a trophy, and it was later carved into a dagger which mysteriously houses some of the beast's magical properties. The dagger grants the wielder the ability to shock an opponent, and has been seen occasionally by traveling heroes throughout history. This particular Fang came into the possession of the Sixth House during the late Third Era. It was reportedly recovered by the Nerevarine and sold to the Mournhold Museum of Artifacts in 3E 427.
There is evidence of a second Fang of Haynekhtnamet, also known as the Swamp Raider's Fang of Haynekhtnamet, which was taken from a wamasu in 2E 582. Fashioned in an Argonian style, this jagged blade was heavily befouled and would cause disease in anyone it struck. When worn with similarly-crafted gear, the blade was also known to magically fortify the wielder's weapon damage and stamina, and could even increase the potency of poison and disease enchantments when the wielder expended magicka.

Fearstruck was a Daedric artifact created by the Daedric Prince Boethiah. It took the form of a shield. It belonged to Lyrisius, a hero from Tamriel famous for leading his army against the Akaviri slavetraders in their homeland of Akavir. The shield was utterly destroyed in the First Era by the fiery breath of a wyrm who Lyrisius encountered after his army was routed. No other reference has ever been made to the shield outside this legend.

Feyfolken is a supposed artifact of the Daedric Prince Clavicus Vile, which is only known from a series of historical fiction books. It is a quill enchanted by a daedra by the name of Feyfolken serving Clavicus Vile at the request of Thaurbad, a sage for the Temple of Auri-El. It transfigures the writing of the user into scripture of unparalleled quality.The trade-off of wielding such an item is that the quill manipulates the thoughts of its beholder.
Fists of Randagulf
The Fists of Randagulf were worn by Randagulf, one of the mightiest warriors from Skyrim in Tamrielic history. He finally lost the gloves, and his life, when High King Harald conquered Skyrim circa 1E 143-1E 221. King Harald respected this great hero and took Randagulf's gauntlets for his own. After King Harald died, the gauntlets disappeared. The King claimed that the Fists granted the bearer added strength.
Flask of Lillandril
The Flask of Lillandril is a magical flask that absorbs and reflects magic of all kinds. Its anti-magic property also prevents mages from detecting its location. The flask was discovered around the year 1E 470 by a group of elves living in the Summerset Isle city of Lillandril. The elves spread news of their discovery, enough to make it an artifact of song and legend. It became the city's symbol and was displayed on their banners.
The elves used the flask to perform favors for the barons of Summerset Isle by keeping in check the magical power of the Bosmer in Valenwood. One legend says that a stable boy defeated the High Wizard of Valenwood using only the flask. After some time, the elves who discovered the flask feared that Bosmer assassins would kill them, so they fled for Daggerfall, hoping to buy safety from the Direnni. The elves shipwrecked off the southern coast of Stros M'Kai, killing all of them according to legend, and the Flask of Lillandril was lost.
The general location of the flask, however, was not lost. Sometime after the shipwreck, a map was created showing its location relative to a wayshrine to Leki in the town of Saintsport. The map was torn into four pieces; one of them was later inscribed on a ship model made of silver and another on the back of a Restless League insignia. Some think there was a survivor of the shipwreck who hid the flask on land and made the map. Additionally, ancient fragments of a manuscript called the Lagan Text contain references for a second map that clarifies the orientation of the first map.
Into the late Second Era, treasure hunters from all over Tamriel searched for the flask to no avail. During its occupation of Stros M'Kai, the Third Empire also searched to some degree, possibly to dispel the magical defenses of the Summerset Isles and start an invasion.
In 2E 864, Cyrus learned about the flask and was able to piece together the map showing its location. He discovered it contained within a chest buried in the sand not far west of Saintsport. With this flask, he was able to defeat the Sload necromancer N'Gasta by reflecting the spells cast at him. He gave it to Clavicus Vile in exchange for his sister's soul, but Vile took it as a present instead and required that he solve a riddle to win back the soul.
The Folium Discognitum is a Daedric artifact created by Sheogorath. It is a tome of knowledge, filled with insights compiled from the ramblings of madmen. The pages bear near incomprehensible scrawls that move to avoid your gaze when read. The power obtained from reading these insights is the equivalent of absorbing at least six skyshards.
Sheogorath has been known to offer the tome to mortals as part of a deal. Arch-Mage Shalidor, ever hungry for knowledge, traded the island of Eyevea for the tome in the First Era. He went on to regret the deal, and in 2E 582 he returned to Tamriel to win back Eyevea from Sheogorath. Valaste, the Mages Guild's Master of Incunabula who aided Shalidor in his attempt, was slowly driven mad by Sheogorath. When the time came to reclaim the island, the Mad God gave an adept of the guild the choice to either restore Valaste's sanity, or take the Folium and allow Valaste to remain in the Shivering Isles for eternity. It is unknown which option was taken.
Fork of Horripilation
The Fork of Horripilation is a cursed artifact created by the Daedric Prince Sheogorath, who refers to it affectionately as Forky. In appearance and in function, it is a mundane iron fork. However, it is imbued with an enchantment which excites and synergizes magicka around it, and can produce dramatic results when held by certain people. Sheogorath is fond of forcing mortals to use it as a weapon, in which case it curses the wielder with Fork's Wound, a magical effect which stunts the wielder's magicka or drains it completely. The Fork smells lightly of roast beef. It is unknown what relation the fork has to horripilation.
In the Merethic Era, Sheogorath paid a visit to the Dragon Priest Korthor in Vuldngrav, during the time of the Dragon Cult in Skyrim. The Mad God "lost" the Fork during this visit, and Korthor was later entombed in Vuldngrav with it. In 2E 582, Arch-Mage Shalidor and the Soulless One recovered the Fork from Korthor during one of Sheogorath's trials.
In 3E 427, the fork was in the possession of Big Head, a mad Argonian hermit and a worshipper of Sheogorath who lived in a small shack on an island in the Sheogorad region of Morrowind. Big Head was obsessed with forks and spears, which he had filled his hut with. Sheogorath instructed the Nerevarine to kill a giant Bull Netch with the fork. Big Head willingly gave the fork to the Nerevarine, who then killed the Bull Netch and returned the fork to Sheogorath to earn the Prince's favor.
In 3E 433, Sheogorath returned the fork to the Shivering Isles, his Plane of Oblivion. Rumors circulated among the mortal population of the Isles about its return. Big Head entered the Isles in search of the fork, which "sang" to him, and took up residence in Bliss, where he collected a great many forks. The fork was of great importance to both the Heretics and Zealots, two outcast religious factions. The Heretics had obtained possession of the fork and had taken it to Longtooth Camp, near the Gates of Madness on the Mania side of the Isles. However, news of this reached the Zealots, who launched an attack on the Heretic base. The Fork supposedly changed hands several times, with the Zealots bringing it to Hardscrabble Camp, their nearby base in Dementia, only to have it reclaimed by the Heretics. Eventually, Big Head requested the assistance of Sheogorath's Champion, who then learned of its location from the beggar Bolwing. The Champion recovered the fork from the outcasts and returned it to the grateful Big Head.
In 4E 201, Sheogorath used the fork to pin a note to a wooden keg in The Retching Netch, a cornerclub in Raven Rock on the island of Solstheim. The note proposed a combat trial, offering the Staff of Sheogorath to whoever used the fork to kill two specific Bull Netches on the island in single combat. The Last Dragonborn accepted the challenge and killed the netches, retrieving from their corpses the necessary components to craft the Staff of Sheogorath.
