The Once and Future King Book 3, Chapter 25
Fifteen years later, things are much the same between Lancelot, Guenever and Arthur, but the court has changed: the knights are younger men who have admired Arthur and Lancelot from their childhood. Arthur's vision of law has evolved, bloodily: even Pellinore was finally murdered by Gawaine, in revenge for the murder of King Lot. Everyone is much more civilized, from the way they fight to the way they eat dinner. Gareth and Mordred both come to court at this time.
