Here are some key aspects of Mordred's character and role in the Arthurian legends:
Betrayal: Mordred is known as the primary antagonist in several versions of the legend. He betrays Arthur at various points in the tale. In some legends, Mordred colluded with Arthur's enemies, particularly Lancelot, to undermine Arthur's rule.
Illegitimate son: Mordred's origins vary in different interpretations, but he is commonly depicted as the result of an affair between Arthur and his half-sister. This lineage adds a dimension of moral conflict and familial tension to his character.
Conflict with Lancelot: In some versions, Mordred is linked to the conflict between King Arthur and the knight Sir Lancelot. Mordred may exploit the tensions between Arthur and Lancelot or manipulate others to fuel conflicts and further his aspirations.
Final Battle: The culmination of Mordred's treachery often leads to the Battle of Camlann, also known as the Battle of Salisbury Plain. It is this battle where Arthur receives his fatal blow from Mordred. Interestingly, in a reversal of their relationship, it is often mentioned that Arthur delivers the lethal strike to Mordred as well.
While versions of the Arthurian legends may differ in specifics, Mordred consistently embodies betrayal, treachery, and rivalry, posing a considerable threat to King Arthur's kingdom and ultimately contributing to the legendary downfall of Camelot.
