But the two chiefs, unmoved by what they had heard from Oisin, said that they would rather perish in seeking out the eric than return to their mother's country. So, leaving their people in the care of Oisin, they set out on their quest. They travelled through the Wood of the two Sallows, and from that to Dooros of the Moy, where they found the track of Dermat and Grania, and followed it till they came to the hunting-booth. Dermat heard their voices and footsteps outside, and, snatching up his weapons, went to the door and asked who was there. "We are Aed, the son of Andala Mac Morna, and Angus, the son of Art Mac Morna," they replied. "We have come hither from Allen of Leinster, to get either the head of Dermat O'Dyna, or a handful of the berries of the quicken tree of Dooros; for Finn, the son of Cumal, has demanded of us that we bring him either the one or the other, as an eric for the killing of his father." Dermat laughed when he heard this, and said, "Truly this is not pleasant news for me to hear, for I am Dermat O'Dyna. But however, friends, I am not willing to give you my head, and you will find it no easy matter to take it. And as for the berries, these are quite as hard to get; for you will have to fight the surly giant Sharvan, who cannot be burned with fire, or drowned with water, or wounded with weapons. But woe to the man who falls under the power of Finn, the son of Cumal. And you have come, methinks, on a bootless quest; for even if you should be able to bring him either of the two things he asks for, he will not grant you the place or the rank ye seek after all. And now," asked Dermat, "which of the two do ye wish to strive for first, my head or the quicken berries?" And they answered, "We will do battle with thee first." So Dermat opened the door, and they made ready for the combat. Now this is the manner in which they agreed to fight: to throw aside their weapons, and to use the strength of their hands alone. And if the sons of Morna were able to overcome Dermat, they should take his head to Finn; but if, on the other hand, they were overpowered and bound by Dermat, their heads should be in like manner forfeit to him. But the fight was, indeed, a short one; for these two chiefs were even as children in Dermat's hands, and he bound them in close and bitter bonds. Now when Grania heard of the berries of the quicken tree, she was seized with a longing desire to taste them. At first she strove against it and was silent, knowing the danger; but now she was not able to hide it any longer, and she told Dermat that she should certainly die if she did not get some of the berries to eat. This troubled Dermat, for he did not wish to quarrel with the giant Sharvan; but, seeing that harm might come to Grania if she did not get the berries, he told her he would go and get some for her, either by good will or by force.
