At length came the end of the year, and on the appointed day the messengers appeared in the wide White Hall of Arthur's castle, and all alike declared that they had no news whatever to declare concerning the maiden Olwen.
Then Kilhugh was very angry, and said in hasty words: "I alone am denied by my lord the gift I ask. I will depart from hence at once, and take with me the honour of Arthur, whom men call the most honourable King." But Kai, one of the knights, reproved him for his angry speech, and offered to go forth with him and any others who would accompany them, saying:
"We will not part till we have found the maiden, or till thou art forced to own she is not among those who dwell on this earth."
So Arthur chose six of his knights to go forth with Prince Kilhugh upon his quest.
First came Kai, whose offer had but just been spoken. An excellent spy and sentinel was he, for he could make himself as tall as the tallest tree in the forest, and so scan all the country round. He could hide himself under water, and lie hidden in lake or river for nine days and nights if need be. Such fire was in his nature that when they needed warmth his companions had but to kindle the piled wood at his finger; he could walk through torrents of rain as dry as on a summer's day; he could go for nine days and nights without sleep, and no doctor could heal the wound made by his sword.
Next came Sir Bedivere, close brother-in-arms to Kai, the swiftest runner, save Arthur himself and one other, in all the land. One-handed was he, yet he could give more wounds in battle than any three warriors together.
Then followed Uriel, who understood the speech of all men and all beasts; and Gawain, who was called the "Hawk of May," because he never returned from any undertaking until it had been performed by him.
The fifth to answer Arthur's call was Merlin, a master of magic, who knew how to put a spell upon the knights that would render them invisible.
Last came Peregrine the Guide, who knew how to find the way as well in a strange country as in his own.
"Go forth, O Chieftains," said the King, "and follow the Prince upon this quest; and great shall be the fame of your adventure."
