It happened on a day that King Arthur journeyed with his knights from Camelot to London, and he lay in his pavilion in the heat of the day. As he rested he heard the noise of a horse, and looking out of the flap of his tent, he saw a strange knight passing, making great complaint and sorrowing, and with him was a damsel. 'Abide, fair sir,' said Arthur, 'and tell me wherefore you are troubled.' 'Ye may little amend it,' answered the knight, and passed on. Later came Sir Balin and saluted the king, who told him of the strange knight sorrowing as he rode, and the king bade him follow and bring back the knight to him, 'for,' said he, 'the sorrows of that knight were so piercing that I would fain know his grief.' Sir Balin took horse and lance and rode many miles through the forest, and by evening he came upon the knight and the lady. 'Sir knight,' said Balin, 'ye must come with me unto my lord, King Arthur, for to tell him the cause of your sorrow.' 'That will I not,' answered the knight, 'for it would do me none avail.' 'Sir, make ready,' replied Balin, 'for ye must needs go with me, or else I will fight with you and take you by force.' 'No heart have I to fight, for all joy of life is dead with me,' said the knight, 'but I am on a fierce quest, and ye must be my warrant if I go with you that I be not kept from my quest.' 'I will gladly warrant you,' said Balin, and together with the lady they turned back. 'I fear not to tell you my sorrow,' said the knight as they rode. 'I but lately returned from fighting the pagans in the north, and when I came to my father's hall, men told me that the lady that I loved most tenderly had been robbed away by a villain knight. And as I sorrowed and went forth to seek the knight to slay him, lo, there I saw my lady, who had escaped unscathed from his evil hold. And much joy we made of each other, for we loved each other tenderly. But even as we kissed, there came an arrow through the air and pierced my dear lady to the heart, so that she fell dead in my arms. And there was none to see who shot the arrow, but men said it was the felon knight who had taken my lady, and he had killed her by black magic. So now with this damsel, my dear sister, who was her friend, do I go through the world seeking the invisible knight. And when I find him, with God's help I will surely slay him.' The good knight Balin was much moved by the sad story. 'Ah!' said he, 'it is the same fell knight whose death I seek by this good sword. And we will fare together, you and I, and take his evil life when God leads us to him.' Even as Sir Balin spoke, out of a dark glade by their side came a lance hurtling, as if held in rest by an invisible rider, and while they turned their heads at the sound of its hissing through the air, it pierced the side of the sorrowing knight and stood deep in the wound.
