Lyric discussion by zhanat1151 

A grandfather takes his two grandchildren away from their town, to live far away, by the sea. Something such as war was happening in their town. They were babies, so he carried them on his back. They left with barely any money, so they lived in a rickety house that rocked in the wind, but the girl knew that she was safe away from the war.

Apparently the grandfather fishes to earn pay, when the lyrics say "the waves that hit his face". He's getting older and more crippled each day.

And after each day of being carefree children, their grandfather would return and the children would begin to notice how old he was getting, worrying them - the "stormy nights". But their grandfather - Finner - tells them not to worry.
