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. 'If I slay him here in this crowded hall,' he said, 'I shall surely not escape, and if I leave him now, peradventure I shall never meet with him again, and much evil will he do if he be let to live.' He could not remove his eyes from Sir Garlon where he walked between the tables, proudly talking and laughing with those he knew, and making soft speeches to ladies, though many showed fear of him, and crossed their fingers while he spoke to them, to fend off the evil of his eyes. Very soon Sir Garlon noticed the fixed, stern look of Sir Balin, and came across to him and flicked his gauntlet across his face. 'This shall make thee remember me when next thou seest me, knight,' he said. 'But thou hadst better do what thou camest for, and fill thyself with mead.' 'Thou sayest sooth,' said Balin, and clutched the sword under his robe. 'Too long hast thou done evil and despite, and now will I do that for which I came.' Rising, he drew his sword fiercely and swiftly, and cleaved the head of Garlon to the shoulders. 'Give me the truncheon wherewith he slew thy brother!' said Balin to the damsel beside him. From beneath her robe the lady brought forth the broken truncheon, and striding to the slain man, Sir Balin thrust it fiercely into his body. 'Now,' cried he aloud, 'with this lance thou didst treacherously slay a good knight, and for that and all thy other cruel murders have I slain thee.' With that arose a great outcry, and men ran from the tables towards Sir Balin to slay him, and the foremost of them was King Pellam, who rushed towards him, crying: 'Thou hast slain my brother when he bore no sword, and thou shalt surely die.' 'Well,' said Balin, 'come and do it thyself.'
