As the first knight struck, Alveric parried, and stopped the blow, but there came a shock like lightning into his arm and the sword flew from his hand, and he knew that no earthly sword could meet the weapons of Elfland, and took the magical sword in his right hand. With this he parried the strokes of the Princess Lirazel's guard, for such these four knights were, having waited for this occasion through all the ages of Elfland. And no more shock came to him from any of those swords, but only a vibration in his own sword's metal that passed through it like a song, and a kind of a glow that arose in it, reaching to Alveric's heart and cheering it. But as Alveric continued to parry the swift blows of the guard, that sword that was kin to the lightning grew weary of these defences, for it had in its essence speed and desperate journeys; and, lifting Alveric's hand along with it, it swept blows at the elvish knights, and the armour of Elfland could not hold it out. Thick and curious blood began to pour through rifts in the armour, and soon of that glittering company two were fallen; and Alveric, encouraged by the zeal of his sword fought cheerily and soon overthrew another, so that only he and one of the guard remained, who seemed to have some stronger magic about him than had been given to his fallen comrades. And so it was, for when the Elf King had first enchanted the guard he had charmed this elvish soldier first of all, while all the wonder of his runes were new; and the soldier and his armour and his sword had something still of this early magic about them, more potent than any inspirations of wizardry that had come later from his master's mind. Yet this knight, as Alveric soon was able to feel along his arm and his sword, had none of those three master runes of which the old witch had spoken when she made the sword on her hill; for these were preserved unuttered by the King of Elfland himself, with which to hedge his own presence. To have known of their existence she must have flown by broom to Elfland and spoken secretly alone with the King. And the sword that had visited Earth from so far away smote like the falling of thunderbolts; and green sparks rose from the armour, and crimson as sword met sword; and thick elvish blood moved slowly, from wide slits, down the cuirass; and Lirazel gazed in awe and wonder and love; and the combatants edged away fighting into the forest; and branches fell on them hacked off by their fight; and the runes in Alveric's far-travelled sword exulted, and roared at the elf-knight; until in the dark of the wood, amongst branches severed from disenchanted trees, with a blow like that of a thunderbolt riving an oak tree, Alveric slew him. At that crash, and at that silence, Lirazel ran to his side. "Quick!" she said. "For my father has three runes ..." She durst not speak of them. "Whither?" said Alveric. And she said: "To the fields you know." CHAPTER IV
