Duke Thadon
	Duke Thadon
Died	3E 433;
Resided in	New Sheoth
Appears in	Shivering Isles, Legends

Thadon was a Bosmer madman and Duke of Mania at the beginning of the Greymarch of 3E 433. He resided in the House of Mania in the Shivering Isles. Thadon was known for his extreme debauchery and self-indulgence. This hedonistic lifestyle eventually led to a deterioration of his mental faculties, resulting in the Duke spending much of his time in a drug-fuelled haze. He is associated with the Diadem of Euphoria, an enchanted crown.^[1]

At some point, Thadon had a forbidden affair with Syl, the Duchess of Dementia. When this affair came to an end, Syl stole the Chalice of Reversal from Thadon as an act of revenge and hid it in Dunroot Burrow; without the Chalice, Thadon could not negate the harmful effects of Felldew, a cripplingly addictive drug. In 3E 433, Sheogorath sent the Hero of Kvatch to Thadon's court to become a courtier of the House of Mania. Thadon tasked the Hero with retrieving the Chalice from Dunroot Burrow, a root tunnel which cannot be entered without first ingesting Felldew.^[1]

The Hero later began the Ritual of Accession to become a Duke or Duchess of Mania or Dementia, although it is unknown if the Hero chose to replace Syl or Thadon. Regardless, the surviving ruler promptly defected to Jyggalag and became a Priest of Order, betraying the Army of Sheogorath and ultimately perishing within the tunnels of the Fountainhead.^[2]
