Daedric N-V

Namira
Namira is the Daedric Prince whose sphere is the ancient darkness. She is associated with all things generally considered repulsive, including various creatures such as spiders or slugs and disease that cause any kind of unattractive physical abnormalities. Namira's followers keep to themselves and prefer living peacefully in dark and squalid conditions but will react violently at any attempts to "save" them from their abysmal, minimalistic lifestyles. Her quest in Oblivion involves working with outcasts to ambush a group of priests under Arkay who attempt to "save" Namira's dark followers.

Nocturnal
Nocturnal is the Daedric Prince whose sphere is the night and darkness, also known as the Night Mistress. The Cyrodilic Thieves Guild leader, The Gray Fox, has the Gray Cowl of Nocturnal, which truly represents the sphere's darkness quality; it permanently removes the wearer's specific identity from all history. According to an account of a Blind Moth Priest, this is to prevent anyone from remembering the face of Nocturnal, for to do so would be to go insane.

Nocturnal's second artifact is the Skeleton Key, an unbreakable lockpick that allows even unskilled users to pick the most complicated locks.

Peryite
Peryite, also known as the Taskmaster, is the Daedric Prince whose sphere is Pestilence, and he is charged with ordering the lowest levels of Oblivion. He is often depicted as a green Dragon and is ostensibly concerned with ensuring all things are accounted for, neat, tidy, and in their proper order.

Peryite's artifact is an enchanted shield, the Spell Breaker,which may reflect spells back to the caster and, in Skyrim, possesses the ability to create a ward against the damaging effects of spells.

He is known to be one of the weakest of Daedric Princes, despite being depicted as a Dragon.

Sanguine
Sanguine is the Daedric Prince whose sphere is hedonistic revelry, debauchery, and passionate indulgences of darker natures. He often appears on the seals and signs of brothels and whore-houses.

Sheogorath
Sheogorath in the Shivering Isles. Sheogorath is the infamous Prince of Madness, whose motives are unknowable. His realm in Oblivion is The Shivering Isles, and is served by the Golden Saints and Dark Seducers.

Sheogorath savors the act of driving mortals insane or making them perform actions that may be seen as trivial or silly. Sheogorath speaks with an almost exaggerated Scottish accent in the Shivering Isles. His favored weapon for mortals is the staff Wabbajack, which can transform any living creature into another random creature.

Another artifact known as the Staff of the Everscamp, which the owner cannot discard, causes the owner to be constantly followed by four scamps. There is also a region in Morrowind named after him, Sheogorad. There are many Daedric shrines there, many of which are shrines built specifically for his followers to worship him. As the Madgod, Sheogorath himself considers madness to be a form of mercy for those who would otherwise not function in the world — "a bitter mercy, perhaps, but a mercy nonetheless".

Some sources state that Sheogorath came into existence with Nirn as the "Sithis-shaped hole in the world." However, it is learned in Shivering Isles that the other Daedric Princes feared the Daedric Prince of Order (Jyggalag) was becoming too powerful, and so they cursed him into a body of madness (Sheogorath), everything he stood against. Though Sheogorath seems to prefer this new existence and to care in his own way for the residents of the Shivering Isles, Jyggalag is nonetheless able to return at the end of every era, leading a "Greymarch" (destruction of the realm using the Knights of Order). The curse would then revert him to Sheogorath, leaving Sheogorath to once again re-assemble his realm.

Not wanting to see his beloved Shivering Isles destroyed again by the Greymarch, Sheogorath called for a champion from Nirn. At the end of the 3rd Era, Jyggalag was struck down by Sheogorath's Champion. With this, the Greymarch was ended prematurely, releasing Jyggalag from the cycle, and the Hero was crowned the new "Sheogorath." Jyggalag says that the hero may one day grow into their new role.

Vaermina
Vaermina is a Daedric Prince whose sphere is the realm of dreams and nightmares, and from whose realm issues forth evil omens. Some have also claimed her sphere ties somehow to torture. Vaermina is depicted as a grotesque old woman. Her plane of Oblivion is "Quagmire." It is described as a nightmare realm, where every few minutes reality shifts and becomes ever more horrifying.
