This is interrupted by the tidings of Mordred's treachery, and Lancelot, taking no part in the last fatal conflict, outlives both king and queen, and the downfall of the Round Table.
In the pseudo-chronicles, the Historia of Geoffrey and the translations by Wace and Layamon, Lancelot does not appear at all; the queen's lover, whose guilty passion is fully returned, is Mordred.
On receipt of the tidings of Mordred's treachery, Gawain accompanies Arthur to England, and is slain in the battle which ensues on their landing.
A curious fragment of Welsh dialogues, printed by Professor Rhys in his Studies on the Arthurian Legend, appears to represent Kay as the abductor, In the pseudo-Chronicles and the romances based upon them the abductor is Mordred, and in the chronicles there is no doubt that the lady was no unwilling victim.
On the final defeat of Mordred she retires to a nunnery, takes the veil, and is no more heard of.
