Lancelot

Lancelot is a young swordsman who saved Merlin from being killed by a Griffin. He reveals to Merlin that his village was attacked when he was a child, resulting in the death of his parents. Thereafter he swore to devote all his time to becoming a knight.

When it is revealed only noblemen can join the Knights of Camelot, Merlin uses his magic to create a seal of nobility. Lancelot tries out for the knights and, although at first Arthur is unimpressed, he quickly identifies that Lancelot has potential and accepts him into the knights of Camelot.

However when Uther asks Geoffrey of Monmouth to check the seal of nobility it is revealed to be a forgery and Lancelot is thrown in prison. Arthur, however, lets him out and tells him to leave Camelot and never return.

When the Griffin attacks again Arthur and the other knights are nearly all killed. Lancelot tries to kill the Griffin but it is only when Merlin enchants his lance the Griffin is killed. Arthur then appeals to Uther to reinstate Lancelot as a knight, thinking it was Lancelot who killed the Griffin.

Lancelot reveals to Merlin that he knows he is a magician and promises to keep his secret, however he also says he cannot stay and take credit for killing the Griffin when it was really Merlin. He announces to Uther and Arthur that he intends to leave in order to redeem himself for lying to them. (Lancelot)

Lancelot traveled around after leaving Camelot and eventually started to earn a living by fighting for entertainment, believing his life had become meaningless. He was working in a fighting ring run by a group of bandits when he heard Gwen had been kidnapped. The bandits had mistaken her for Morgana and was holding her for ransom. Realizing Gwen's life would be in danger if she was found to not be Morgana, Lancelot worked to free her. Gwen confessed that she never stopped feeling for him, giving Lancelot a reason to live again. When they tried to escape, they were captured and set to be executed. But they were saved by Arthur and Merlin, who had come to rescue Gwen.

While returning to Camelot, Lancelot talked to Merlin and came to realize that Gwen and Arthur were falling in love. Though he had realized his own feelings for Gwen, Lancelot decided he wouldn't risk coming between her and Arthur. He left once again, asking Merlin to tell Gwen that while they weren't meant to be, she had changed his life.
