When summer was now over, and the first snow of winter began to fall, when the days were rapidly shortening, and the sun had gone out of the north to the south, where it began to move in a rapidly narrowing arc, Grettir returned to Biarg and remained there a while. "But," says the saga, "so great grew his fear in the dark that he durst go nowhere as soon as dusk set in." We can see that the many years strain on his nerves had broken them. Hunted about as a wild beast, always forced to be on his guard, never able to sleep without fear of being murdered in his sleep, the trial had told on him. This was now the winter of 1028. He was aged but thirty-one; his strength of body was not abated, only his nervous force. He had been in outlawry altogether fifteen years, three for the slaying of Skeggi, then he had been outlawed by King Olaf in 1016. On his return to Iceland he had been outlawed in 1017; this was the eleventh year of his outlawry at the suit of Thorir of Garth, an outlawry not only unjust, but according to general opinion illegal, because he had been tried and sentenced in his absence, and without any witnesses having been called to establish his guilt—condemned on hearsay evidence, and he never allowed to defend himself.

Now Illugi, Grettir's sole surviving brother, was aged fifteen, and was a very handsome, honest-looking boy.

"Grettir," said he, "you know what I said. I will go with you to Drangey, if you will take me. I know not that I will be of much help to you, but this I know, that I will be ever true to you, and will never run from you so long as you stand up. Besides, I shall like to be with you, for here at home we are ever in anxiety for news about you, always fearing the worst; but if I am at your side, I shall know how you fare."

"I would rather have you with me than anyone else," answered Grettir. "But I cannot take you unless our mother consent."

Then said Asdis, "Now I can see that I have the choice of evils. I can ill spare Illugi; yet I know your trouble, Grettir, and that something must be done for you. It grieves me, my sons, to see you both leave me; yet I will not withhold my youngest from you, Grettir. It is right that brother should help brother."

That rejoiced Illugi. Then Asdis gave her sons what things she thought they might want on the island, and they made them ready to depart.

She led them outside the farm inclosure, and then she took farewell of them, saying, "My two sons! There you depart from me, and I dreamed last night that you left me for ever, and would fall together. What is fated none may fly from. Never shall I see you again, either of you. Be it so, that one fate overtake you both. In my dream I saw your bones whitening on Drangey. Be careful and watchful. My dreams have troubled me greatly. Above all beware of witchcraft. None can cope with the craft of the old."

When she had said this she wept sore.

Then said Grettir, "Weep not, mother, for if we be set on with weapons it will be said of thee that thou hadst men and not girls for thy children. Live on well, and be hale."

So they parted. Grettir and Illugi went to their relatives and visited them, never, however, staying long in any place, and so on by Swine Lake, a long sheet of water in a shallow basin, to the Blend River. This river is of the colour of milk and water, because it is so full of undissolved snow, and milk and water is called Bland, i.e. Blend, in Icelandic. Another river enters it that is called the Black Stream, because of the dark colour of the water. Grettir turned up the valley of the Black River and then over a pass by a pretty lake lying in a mountain lap, down into a broad marshy valley in which are three or four rivers, and boiling springs pouring forth clouds of steam on the hill-slopes. The valley is commanded by a beautiful mountain peak, called the Measuring Peak, because the natives thereabouts reckon distances from it.
