Cador (Latin: Cadorius) was a legendary Duke of Cornwall, known chiefly through Geoffrey of Monmouth's pseudohistorical History of the Kings of Britain and previous manuscript sources such as the Life of Carantoc. Early sources present Cador as a relative of Arthur, though the details of their kinship are usually left unspecified.
Cado was the historical son of a Dumnonian king named Gerren whom he succeeded as monarch. Traditionally he was a good friend of Arthur; they even ruled together in the Vita Sanctus Carantoci (Life of St. Carantoc). He also seemed to share a good relationship with King Caradoc of Gwent. Possibly he gave his name to four hillforts, all named Cadbury which may be "Cado's fort", one each near to Clevedon, Congresbury and Sparkford in Somerset and one by the Exe in Devon north of Crediton).
In Geoffrey's History and elsewhere, Arthur's future queen Guinevere was raised as Cador's ward. Cador is also said to be of Roman stock. His son Constantine was given the kingship of Britain by Arthur as the latter lay ailing on the field of Camlann. To the Brut Tysilio the translator adds the information that Cador was son of Gorlois, presumably by Igraine, which would make him Arthur's maternal half-brother. The same account appears in Richard Hardyng's Chronicle where Cador is called Arthur's brother "of his mother's syde." In Layamon's Brut Cador appears as a leader who takes charge of Uther's host when they are attacked by Gorlois while Uther is secretly lying beside Igraine in Tintagel. Most works, such as the English Alliterative Morte Arthure and Sir Thomas Malory's Le Morte d'Arthur, however, call Cador Arthur's "cousin".
Bastards of madness
Call out this prayer of vengeance
Speaking to enemies through these wounds of redemption
Tearing out their eyes with horror
Behold this chosen new devise
As the silence pleads this forgiveness
A senseless begging for absolution
Upon this entrance into oblivion
This fallen angel of defiance, destitute to isolation
Hold tight to liberation, in the form of reprisal
Project of this restored frame, in these pain filled alterations
This new threat of changing life restless in this completion
Powerless you crawl like pigs
Soon to be slaughtered
Suckling to a faith that you avidly hoped would save you all
These offerings will bring us our justice.
For these years of diluted lies
The answers to our freedom
The answer to the death of gods
These hands held into the sky so the dark
Winds can taste the blood of murder
As the blackest hearts obey thoughts of evil
Deathlorn rites, endure the lust for revenge
Surrender the state of embracement and release
This life from the dark interiors
Discomfort of this assisted torment is given in these regards
A scourge of awakening
Prisoned in the rites of blood
Bestowed with ancient plagues, we will forge a disease
Of rape upon your ideals
Within this lifeblood we will find the truths as blades
Slice open their necks
The answers to our freedom
The answer to the death of gods
Once reconstructed the swarm will digest
The souls of this imperfection
Sterilizing faith bringer has discharged
This assembly of this damnation
Burden me with your weak
Curse me with your sick
In blood filled walls I lie confined
