On his second journey, the god Rig (Heimdall) came upon a well-maintained house, owned by an artisan and farmer. The man and woman who lived there were Afi and Amma, Grandfather and Grandmother. They offered him a decent meal and let him sleep between them in their bed. Nine months later, Amma gave birth to a son, whom they named Karl ("churl"). Afi assumed that the child was his son but Karl was in fact the son of Rig.
