Lancelot du Lac, formerly known as the Knight of the Lake, is an ally to the witch South, and is a former member of the Knights of the Round Table. He protects Guinevere, the Queen of King Arthur, because of his great respect for her and Arthur. Halloween, or Mordred, is the daughter of Guinevere.
Despite betraying Arthur, Lancelot still holds him in high respect, saying, "Arthur, if it is not a place where you rule, then I will have no mercy."
Lancelot holds a great grudge against Tasha because of his contract with Halloween. He and Guinevere attempt to break it with her Egg of Beginning, but Tasha's relationship with Halloween proves too strong for it.
Trivia
His hobbies include collecting poetry books, and he's apparently also written some himself. He likes Guinevere, King Arthur, the Knights of the Round Table, chivalry and nice poetry. He dislikes un-chivalrous people and himself (see below).
Curiously, it's written is his character biography that he hates himself. It may be a reference to T.H. White's novel Once and Future King, which is about the times of Camelot, in which Lancelot is depicted as a self-hating character.
