In Langadalur, you can find a country where humans can only exist as the companions of elemental powers. To walk here is to be utterly naked in the universe. To do so with a community of people is no help. You must enter with a community of things, and live within them until you have crossed. What the Icelanders have learned in 1100 years is that when the boat doesn’t come, you had better be good at making a new community of things.
You must halter yourself to the Earth, lest you are blown away. You could say that Gunnar returned to Iceland in 1939 because he loved his land, which is true, that he was romantic, which is also true, that he was afraid, which was reasonable in 1939, and you could say that this fold east of Bifrost is an instance of creativity, which is also true, but those are just words. You pick up the Earth one stone at a time, and move them to create a body that shelters you. It is your companion. It is yourself. From their to haunting is not far.
