There are over one hundred characters in the full-blown Arthurian Legends. In my opinion the most difficult by far to write well is Lancelot. If Arthur and Merlin are the foundation, then Lancelot is the keystone. His strengths and virtues bind together the soaring arch of Arthurian Chivalry, and his weaknesses bring it crashing down. So it is absolutely essential that any retelling establish at Lancelot's introduction his strength, his courage, his valor, his selflessness, his beauty, his kindness, his respect and utter adoration for Arthur, his love of Guenevere, his desperation to do anything to prove himself, and his fatal willingness to let those he cares about talk him into doing things that he knows are bad ideas.
