According to Wikipedia: "Njáls saga ... or "The Story of Burnt Njal" is one of the sagas of Icelanders. The most prominent characters are the friends Njáll Þorgeirsson, a lawyer and a sage, and Gunnarr Hámundarson, a formidable warrior. In the course of a feud, Gunnarr is exiled and must leave Iceland but as he rides away from his home he is struck by the beauty of the land and resolves to stay; this quickly leads to his death. Some years later, Njáll is burned alive in his home as a part of a cycle of killing and vengeance.”
