Fictional squires

Mordred or Modred ( or ; Welsh: Medraut or Medrawt) is a major 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.
