There had been so many brave men in that fight, but no Lancelot. In all the years that I had fought for Arthur, and in all the years that I had been acquainted with Lancelot, I had yet to see Lancelot in the shield-wall. I had seen him pursuing beaten fugitives, and seen him lead captives off to parade them before an excited crowd, but I had never seen him in the hard, sweaty, clanging press of struggling shield-walls. He was the exiled King of Benoic, unthroned by the horde of Franks that had erupted out of Gaul to sweep his father’s kingdom into oblivion, and not once, so far as I knew, had he ever carried a spear against a Frankish war-band, yet bards throughout the length and breadth of Britain sang of his bravery. He was Lancelot, the King without land, the hero of a hundred fights, the sword of the Britons, the handsome lord of sorrows, the paragon, and all of that high reputation was made by song and none of it, so far as I knew, with a sword. I was his enemy, and he mine, but both of us were friends of Arthur and that friendship kept our enmity in an awkward truce.

Arthur knew my hostility. He touched my elbow so that we both walked on south towards the tide-rill of the dead. ‘Lancelot is Dumnonia’s friend,’ he insisted, ‘so if Lancelot rules Siluria then we shall have nothing to fear from it. And if Lancelot marries Ceinwyn, then Powys will support him too.’

There, it was said, and now my hostility was brittle with anger, yet still I said nothing against Arthur’s scheme. What could I say? I was the son of a Saxon slave, a young warrior with a band of men but no land, and Ceinwyn was a Princess of Powys. She was called seren, the star, and she shone in a dull land like a spark of the sun fallen into mud.
