Many years after the events foretold by Morgan come to pass, Sir Dinadan reaches the age of seventy. Camelot has become the capital of a small kingdom holding out against the Saxons, ruled by King Bedivere, Guinevere's son by her second marriage to the former king of Glamorgan, named after her most loyal protector.

Dinadan, now widowed but still strong, is seized by the same wanderlust that once drove Sir Palomides. He dons his old armor, leaves Camelot, and sails east, riding through the Ostrogothic Kingdom, the Byzantine Empire, the Sassanid lands, the Turkic Khaganate, and beyond. His journey is a pilgrimage with no destination, fueled only by the compulsion to keep moving.

He travels until he reaches a land where the names Arthur and Camelot mean nothing. Unbeknownst to him, he is the last surviving knight of the Round Table. When his time comes, he lies down beneath an ancient olive tree, accompanied only by his horse and a small luminous bird, and dies wondering why humans are made for a bright world but live in a dark one.
