Lancelot is, of course, the premiere knight in the
court of King Arthur. On the battlefield, he is almost unbeatable.
In his adventures, Lancelot slays all manner of
annoying evil knights, and is granted, due to his purity of heart, a vision
of the holy grail.
What makes Lancelot interesting, however, is the
central role he plays in the fall of Camelot due to his love of Queen
Guinevere and his killing of Gareth, brother to Gawaine.
