Beginning with Guinevere reflecting while imprisoned before being burnt at the stake for her affair with Lancelot, Guinevere retells the quest of the Holy Grail, the coming of Perceval and Gareth to the court and Mordred's rebellion with his brothers Agravain and Gaheris.
These four children (Gawain, Agravaine, Gaheris, and Gareth) become major characters for the rest of White's work.
