Firstly, certain superstitions were attached to hospitality; in some Norse sagas, we see evidence that it was considered unlucky for a guest to knock after the sun has set. Secondly, there was as much horror at the notion of killing your own guests as there was at the notion of killing your own family; giving or receiving hospitality was regarded as a kind of distant kinship. These norms applied to the Norse gods as well. Even the gods’ direst and most violent enemies were served as guests to their hearts’ content if they came within the walls of the gods’ enclosure.
