Sigurd was succeeded in the earldom by his son Guttorm. Guttorm ruled the islands for one short and uneventful winter, and then died childless. For some time the earldom was without a ruler. Vikings once more began to make the Orkneys their headquarters, and to harass the more peaceful inhabitants of the islands. When King Harald heard that the Orkneys were without a ruler, he asked Earl Rognvald to make haste to send them another earl. Rognvald then had the title of Earl of Orkney conferred on his son Hallad, who sailed for the west as the third earl. But Hallad was weak and indolent. The western earldom was too turbulent and difficult to govern. He soon wearied of his dignity, and at last, deserting his earldom, went back to Norway. After his ignominious withdrawal from the earldom, the islands came under the rule of two Danish Vikings. Although Hallad preferred a simple farmer’s life to an earl’s dignity, there were others of Rognvald’s sons who were more ambitious. Einar especially was eager to redeem the family honour by the expulsion of the Vikings from the islands. Accordingly Einar was chosen as Earl of Orkney, and after King Harald had conferred on him the title, he set out for his earldom. The old Earl of Moeri had never regarded his youngest son with much favour, and, to tell the truth, neither desired to see the other’s face again. Einar was the best and greatest of the early Norse earls. In appearance he was tall and manly; his face was somewhat disfigured by the loss of an eye, but in spite of this he was reputed to be very sharp-sighted. His father had prophesied that Einar would never become a great chief; yet he became the most famous of all Earl Rognvald’s sons, with the exception of Rollo of Normandy. The earldom was in a state of great disorder when Einar arrived. The Vikings had to be expelled, the government had to be settled and established, and the people had to learn to trust and obey their new earl. All these things were accomplished in a marvellously short space of time. The new earl also taught his people many useful arts. Wood was scarce: Einar knew that the people of Scotland used peat for fuel, and he taught the Norsemen in the islands to do the same. From this he got the name of Torf-Einar. Soon a serious trouble arose. King Harald’s sons had now grown up to be very turbulent and overbearing men. They quarrelled with their father’s chiefs and earls. Two of them, Halfdan Highleg and Gudrod Bright, attacked and slew Rognvald, Earl of Moeri. Harald was enraged that his sons should thus murder his best and most faithful counsellor and friend. He marched against them with an army, and ordered them to be seized and brought before him. Gudrod gave himself up to his father, but Halfdan seized a ship and sailed west to the Orkneys.
