Thereupon King Arthur knighted Perceval, and they made him great cheer and welcome; and the king knew in his heart that this was one of the three good knights whom St. David had spoken of, and he wondered who were the other two.
It chanced that seven nights before, the good Sir Bors had fared forth from the court of Arthur to seek knightly adventures. And his spirit was joyful as he rode, for he felt that some great adventure was to come to him, howbeit he knew not why he felt this was to be.
Northward he fared through the land, and the snow had not yet fallen, but so mild was the season that men's thoughts had stirred towards spring. For many days he journeyed and the ways were more lonely, the country more desolate, the rocky hills more bare. He wondered why it was that the land seemed so forsaken, as if the folk had long since left the fields to become solitary wastes.
At length it befell that one evening he could find no place wherein to shelter for the night; there was no hermit's cell nor castle nor knight's hold through all the way by which he had come that day. Towards twilight he came upon a wide moor, and the cold moon peered at him over the distant mountains. Far in the midst of the waste he saw a great pile, as of a castle, and pricked his horse towards it.
It was indeed a castle, but its walls were broken and mossy, as if long years had passed since it housed fire and gay company. He rode over the drawbridge into the great courtyard, and the echo of his horse's hoofbeats was the only sound that greeted him.
He sought the upper chambers, and found in one a rough bed of fern leaves, and, having supped from the scrip he carried with him, he composed himself to sleep, glad that at least a roof and thick walls shielded him from the freezing cold which now swept over the land.
Forthwith he slept; but at midnight he awoke and found it was deeply dark, and looking to the arrow slit in the wall he sought some friendly star. As he looked, a great red light burst through, and with that there came, thrusting fiercely, a great spear like a long flame, which darted at him, and then stayed just before him. The point of it burned blue and dazzling.
As he lay marvelling, the spear went back a space; then he grasped his sword that lay beside him, but before he could defend himself the flaming spear dashed forward again and smote him in the shoulder.
Then the spear went back and the chamber was deep dark again, and for very pain Sir Bors lay and groaned. Nor could he sleep more that night. When it was dawn he arose, thinking to ride forth, but when he went down into the courtyard to saddle his horse in the stable, he marvelled to see that where there had been an open ruined gateway the night before, was now a great black oaken door, spiked and bolted.
For a long time he essayed by every means to get himself out of that castle, but he could not find a way. Yet never did he hear or see aught that showed that any one lived there. Many times he went throughout the place, but never found aught but ruin and emptiness, and the dust and darkness of long neglect everywhere.
