They say in the beginning there were 16;
Azura, Daedric prince of dusk and dawn
Boethiah, Daedric prince of deceit, conspiracy, secret plots of murder, assassination, and treason
Clavicus Vile, Daedric prince of granting of power and wishes through ritual invocations and pact
HermaeusMora, Daedric prince of forbidden knowledge
Hircine, whose Daedric prince of hunt, and father of man beasts
Jyggalag, Daedric prince of order
Malacath, Daedric prince of Orcs
MehrunesDagon, Daedric prince of destruction, change, revolution, energy, and ambition
Meridia, Daedric prince of life
MolagBal, Daedric prince of corruption, rape, and enslavement of mortals
Namira, Daedric prince of ancient darkness, revulsion, and shadowy spirits
Nocturnal, Daedric prince of secrets, thieves, and shadows
Peryite, Daedric prince of pestilence, and ordering the lowest creatures of Oblivion
Sanguine, Daedric prince of hedonistic revelry, debauchery, and passionate indulgences of darker natures
Vaermina, Daedric prince of dreams and nightmares.
Then there was the transformation of Jyggalag into Sheogorath, Daedric prince of madness. However there is one Daedric prince whose name is long forgotten. His sphere was of frustration, annoyance, endless prattling and cowardice. The other princes cast him out of Oblivion to end his campaign of aggravation. He was known by many names, Runt, Blondie, Punk, Kid, and Cone Head. Perhaps his most common name though, is the Adoring Fan.
