It befell that as Gwalchmai went forth one day with King Arthur, he
perceived him to be very sad and sorrowful. And Gwalchmai was much
grieved to see Arthur in this state; and he questioned him, saying,
"Oh, my lord! what has befallen thee?" "In sooth, Gwalchmai," said
Arthur, "I am grieved concerning Owain, whom I have lost these three
years, and I shall certainly die if the fourth year passes without my
seeing him. Now I am sure, that it is through the tale which Kynon
the son of Clydno related, that I have lost Owain." "There is no
need for thee," said Gwalchmai, "to summon to arms thy whole
dominions on this account, for thou thyself and the men of thy
household will be able to avenge Owain, if he be slain; or to set him
free, if he be in prison; and, if alive, to bring him back with
thee." And it was settled according to what Gwalchmai had said.

Then Arthur and the men of his household prepared to go and seek
Owain, and their number was three thousand, besides their attendants.
And Kynon the son of Clydno acted as their guide. And Arthur came to
the Castle where Kynon had been before, and when he came there the
youths were shooting in the same place, and the yellow man was
standing hard by. When the yellow man saw Arthur he greeted him, and
invited him to the Castle; and Arthur accepted his invitation, and
they entered the Castle together. And great as was the number of his
retinue, their presence was scarcely observed in the Castle, so vast
was its extent. And the maidens rose up to wait on them, and the
service of the maidens appeared to them all to excel any attendance
they had ever met with; and even the pages who had charge of the
horses were no worse served, that night, than Arthur himself would
have been in his own palace.
