On the morrow they rode all three towards the town of King Pellam, and when they came within the country of Holy Hallows, Sir Balin saw how fair and happy was the land and its joyful people. Their meadows were rich with grass, the cattle were thriving and sleek, the trees were loaded with fruit and the cornfields full with rich ripe corn.
'Why doth it seem,' asked Balin, 'that this country is the fairest and happiest that ever I saw?'
'It is for this,' said Sir Gwydion, 'that in the Castle of Holy Hallows, whither we wend, King Pellam hath some holy relics of a passing marvellous power, and while he keepeth these his land is rich and happy, and plagues cannot enter it nor murrain, nor can pestilence waste the people.'
When they reached the castle they found a great throng of lords and ladies, and because Sir Gwydion had no lady with him he could not sit at the feast. But Balin was well received and brought to a chamber, and they unarmed him. The squires brought him a festal robe to his pleasure, but he would not suffer them to take his sword.
'Nay,' said he, 'it is my vow that never shall I and my sword be parted, and that vow will I keep or depart as I came.'
So they suffered him to wear it under his robe, and he was set in the hall with his lady beside him. Anon, when the meal was ended and the mead horns were set, Sir Balin asked his neighbour whether there was a knight at that court named Garlon.
'Yonder he goeth,' said the knight; 'he with that dark face and piercing eye. He is the most marvellous knight that is now living, and though King Pellam loveth him dearly, because he is his brother, yet he suffers bitterly the evil magic of Sir Garlon. For that knight rideth invisible, and slays so that none may know how they get their death.'
Sir Balin's heart rose at these words, and he trembled with his great anger.
'Ah, well,' said the good knight. 'And that is he?'
He considered long within himself what he should do.
