Then Gregorius went north to Throndhjem, and came there before Yule. King Inge was rejoiced at his safety, and told him to use his property as freely as his own, King Eystein having burnt Gregorius's house, and slaughtered his stock of cattle. The ship-docks which King Eystein the Elder had constructed in the merchant town of Nidaros, and which had been exceedingly expensive, were also burnt this winter, together with some good vessels belonging to King Inge.
This deed was ascribed to King Eystein and Philip Gyrdson, King Sigurd's foster-brother, and occasioned much displeasure and hatred. The following summer King Inge went south with a very numerous body of men; and King Eystein came northwards, gathering men also. They met in the east (A.D. 1156) at the Seleys, near to the Naze; but King Inge was by far the strongest in men.
It was nearly coming to a battle; but at last they were reconciled on these conditions, that King Eystein should be bound to pay forty-five marks of gold, of which King Inge should have thirty marks, because King Eystein had occasioned the burning of the docks and ships; and, besides, that Philip, and all who had been accomplices in the deed, should be outlawed. Also that the men should be banished the country, against whom it could be proved that they gave blow or wound to King Sigurd; for King Eystein accused King Inge of protecting these men; and that Gregorius should have fifteen marks of gold for the value of his property burnt by King Eystein.
King Eystein was ill pleased with these terms, and looked upon the treaty as one forced upon him. From that meeting King Inge went eastward to Viken, and King Eystein north to Throndhjem; and they had no intercourse with each other, nor were the messages which passed between them very friendly, and on both sides they killed each other's friends.
King Eystein, besides, did not pay the money; and the one accused the other of not fulfilling what was promised. King Inge and Gregorius enticed many people from King Eystein; among others, Bard Standale Brynjolfson, Simon Skalp, a son of Halkel Huk, Halder Brynjolfson, Jon Halkelson, and many other lendermen.
