The castle was guarded by nine warders at the gate and nine watch-dogs along the road which led up to it; but a strange silence had fallen upon both men and beasts, and the Champions slew them all without a sound being heard.
Then they passed through the great door, and entered the hall of the castle.
Just opposite the entrance sat Thornogre Thistlehair upon a high, wide throne. He was terrible to look upon. His eyebrows were so long and bushy that they fell over his eyes like a curtain, and he was taller and broader than three other giants put together. Close by his hand lay three poisoned darts.
After they had greeted him courteously, he asked who they were; and they replied that they were come from Arthur's Court to ask that Olwen, his daughter, should marry Kilhugh the Prince. Then the giant roared for his pages to come and prop up his eyebrows, that he might see what sort of son-in-law was proposed for him.
So when they had propped up his eyebrows he looked angrily at Kilhugh, and bade him come the next day for his answer.
But as they went out of the hall, the giant threw one of his poisoned darts at them. Sir Bedivere caught it just in time and threw it back so neatly that it caught the giant in the knee. Then they laughed, and withdrew, leaving him to storm at them, declaring that the great wound hurt him as much as the sting of a gadfly, and that he might never be able to walk quite so well again.
At dawn the next day they returned to the castle, and again demanded the hand of fair Olwen in marriage. But the giant replied: "I can do naught in this matter till I have consulted her four great-grandmothers and her four great-grandfathers. Come again for my answer."
So they turned to leave the hall; but as they went the giant snatched up the second of his poisoned darts, and flung it after them. Merlin caught it deftly, however, and threw it back with such force that it entered his chest, and stuck out through his back. This left him grumbling that never again would he be able to climb a hill without losing breath, and fearing lest he now might sometimes suffer from pains in the chest.
The third time they visited the giant he was on his guard, and shouted to them not to dare throw any more darts on pain of death. Then he roared to his pages to lift up his eyebrows, and when they had done it, he snatched up the third poisoned dart, and flung it at them without more ado.
But Kilhugh caught it this time, and cast it back at him, so that it pierced one of his eyes. Then, while he grumbled that now his sight would not be so good as before, they went out to dine.
