Guinevere, also often written in Modern English as Guenevere or Guenever, was, according to Arthurian legend, an early-medieval queen of Great Britain and the wife of King Arthur. First mentioned in popular literature in the early 12th century, nearly 700 years after the purported times of Arthur, Guinevere has since been portrayed as everything from a fatally flawed, villainous and opportunistic traitor to a noble and virtuous lady. Many records of the legend also feature the variably recounted story of her abduction and rescue as a major part of the tale.

Mordred or Modred is a figure in the legend of King Arthur. The earliest known mention of a possibly historical Medraut is in the Welsh chronicle Annales Cambriae, wherein he and Arthur are ambiguously associated with the Battle of Camlann in a brief entry for the year 537. Medraut's figure seemed to have been regarded positively in the early Welsh tradition and may have been related to that of Arthur's son.
