What are the motifs in The Vinland Sagas: The Norse Discovery of America ?

Conflict is a recurring idea in the book. The Icelandic Sagas could not be the great works of literature they are without a deep theme of conflict. The Vinland Sagas could not have gotten off the ground unless Eirik the Red's parents were made to flee Norway due to 'some killings'. Eirik the Red himself was involved in a serious conflict with his neighbor.
