King of Estrangor.

Although apparently one of the rebels against Arthur, Karados had been a companion of the Round Table (during the time of Uther Pendragon?). He did not occupy his seat during the rebellion.

It's not sure whether or not he should be identified with either King Carados of Scotland, Sir Carados of the Dolorous Tower, or Carados of Cornwall, father of Constantine who became King after Arthur.
