After the death of Einar, Brusi took possession of his share by virtue of their agreement of joint survivorship. Thorfinn thought they should each have one-half, but Brusi would not yield. Seeing, however, that he could not contend with Thorfinn, who had great estates in Scotland and the support of his grandfather, the Scottish King, Brusi decided to go to King Olaf, taking with him his son Rognvald, then ten years old. Thorfinn hearing of this, and recalling his former favourable reception from that sovereign, also hastened to Norway, where their disputes were settled by the arbitrament of Olaf, who adjudged one-third to himself as the forfeited share of Earl Einar for slaying Eyvind Urarhorn, and one-third each to Brusi and Thorfinn, The forfeited share he afterwards gave to Brusi, and further conditioned that the Earls should be reconciled to Thorkell Foster. Thorfinn then sailed west, accompanied by Thorkell, while Brusi did not leave till the autumn next, and his heir, Rognvald, remained with King Olaf. When the brothers Thorfinn and Brusi came to the Islands, Brusi took possession of two-thirds of the domain, and Thorfinn of one, but he was all the time in Caithness, and placed deputies over the Islands. The Isles were in those times very much exposed to the ravages of the Norwegians and Danes, who called there on their viking expeditions to the west and plundered the outlying isles. The defence fell on Brusi alone, who made complaint to Thorfinn about his not contributing to the defence of Orkney and Shetland, although he received his full share of all the land dues and revenues. Then Thorfin n proposed to take two-thirds and defend the whole, leaving Brusi one-third. Although this division did not immediately take place, yet it is said in the History of the Earls that it happened, and that when Knut the Great conquered Norway, after the flight of King Olaf, Thorfinn had two-thirds and Brusi the one-third. After the treaty between the brothers, King Olaf received no homage from Earl Thorfinn. Brusi now disappears from Orcadian history, and his brother comes prominently to the fore.
NOTE - The precise apportionment of Insular Orcadia into trithings is not clear.
