uncle harald 's leg was aching too much to let him sail so far ; aunt anna had not wanted to leave her husband behind , alone in the house ; halfdan 's foster-brothers and foster-sisters ( who were also his cousins ) were all too busy with farms and children ; and uncle gunnar and aunt ragnhild were very angry at halfdan , blaming him for recklessly causing the death of their son , fisk , at the battle of the beacon .
