“Hallmund steps from his mountain hall”;

further: 

“The war-fain sword in Arnarvatn went forth to hew its bloody path.  Heroes inherit Kelduhverfi.  Hallmund the brave came forth from his den.”

It is said that at that encounter Grettir slew six men and Hallmund twelve.

As the summer passed Grettir began to long for the habitations of men, and to see his friends and kinsmen.  Hallmund told him to visit him when he returned to the South and Grettir promised to do so.  He went westwards to Borgarfjord and thence to Breidafjardardalir and sought counsel of Thorsteinn Kuggason as to where he should go next.  Thorsteinn said that his enemies were now becoming so numerous that few would care to take him in; but told him to go to Myrar and see what he found there.  So in the autumn he went to Myrar.

CHAPTER LVIII

Grettir visits Bjorn the Hitdale warrior and takes refuge in the Fagraskogafjall

There lived in Holm Bjorn the Hitdale Warrior, who was the son of Arngeir, the son of Bersi the Godless, the son of Balki, who was the first settler in Hrutafjord, as has already been told.  Bjorn was a great chief and a valiant man, always ready to take in outlaws.  He received Grettir well when he came to Holm on account of the friendship which had existed between their former kinsmen.  Grettir asked if he would give him shelter, and Bjorn said that he had so many quarrels throughout the land that men would be reluctant to take him in for fear of being outlawed themselves.  “But,” he said, “I will give you some help if you will leave the men who are under my protection in peace, whatever you do to others in this part.”

Grettir promised that he would, and Bjorn continued:  “I have thought of something.  In the mountain which stretches away from the Hitara river there is a good position for defence, and likewise a good hiding-place if it is skilfully managed.  There is a hole through the mountain from which you can see down upon the high road that lies immediately beneath it, and a sandy slope down to the road so steep that few could get up it if it were defended above by one doughty man up in the hollow.  It may, I think, be worth your while to consider whether you can stay there; it is easy to go down from there to the Myrar to get your supplies, and to reach the sea.”

Grettir said he would trust to his foresight if he would help him a little.  Then he went to Fagraskogafjall and made himself a home there.  He hung some grey wadmal in front of the hole, and it looked from the road below as if one could see through.  Then he began to get in his supplies, but the Myramen thought they had an unhappy visitor in Grettir.
