“When Egil was twelve years old, he was grown so big that there were but few men howso large and strong that he could not overcome in games. In his twelfth winter he was often at games. Thord Grani's son was then twenty years old; he was very strong. As the winter wore on, if often chanced that the two, Egil and Thord, were matched against Skallagrim. And once in the winter it so befell that there was ball-play at Borg, southwards in Sandvik. Thord and Egil were set against Skallagrim in the game; and he became weary before them, so that they had the best of it. But in the evening after sunset it began to go worse with Egil and his partner. Skallagrim then became so strong and he caught up Thord and dashed him down so violently that he was all bruised and died on the spot. Then he seized Egil.
Now there was a handmaid of Skallagrim's named Thorgerdr Brak, who had nursed Egil when a child; she was a big woman, strong as a man, and of magic cunning. Said Brak:
'Dost thou turn they shape-strength, Skallagrim, against thy son?'
Whereat Skallagrim let Egil loose, but clutched at her. She broke away and took to her heels with Skallagrim after her. So went they to the utmost point of Digra-ness. Then she leapt out from the rock into the water. Skallagrim hurled after her a great stone, which struck her between the shoulders, and neither ever came up again. The water there is now called Brakar-sound.

But afterwards, in the evening, when they came home to Borg, Egil was very angry. Skallagrim and everybody else were set at table, but Egil had not yet come to his place. He went into the fire-hall, and up to the man who there had the overseeing of work and the management of moneys for Skallagrim, and was most dear to him. Egil dealt him his deathblow, then went to his seat. Skallagrim spoke not a word about it then, and thenceforward the matter was kept quiet. But father and son exchanged no word good or bad, and so that winter passed.”
