At the age of fifteen, he traded to Grimsby, where many Norwegians and Orkneymen came, and many from the Hebrides; and here he met Harald Gillikrist, who became his firm friend, and confided in him alone that he, Harald, was the son of King Magnus Barelegs, asking how he would be received by King Sigurd of Norway, and obtaining the diplomatic reply that he would be well received by the king, if others did not spoil his welcome. Then Kali returns to Bergen in 1116, about the time of Jarl Magnus' murder by his cousin Jarl Hakon, and after a friendship and a feud with Jon Peterson, which is amicably settled by the marriage of Jon with Kali's sister Ingirid, and of which the description well illustrates the manners and law of the times, is made Jarl Ragnvald of Orkney by King Sigurd; and on that king's death in 1126 he is confirmed in the title by his friend King Harald, for whom he fought in the battle for the throne at Floruvoe near Bergen, when King Magnus was captured, maimed, and deposed by Harald in 1135. Jarl Paul, however, refused to part with half the isles; and, acting on Kol's advice, Jarl Ragnvald's messengers apply for aid in obtaining it to Frakark and her grandson Olvir Rosta in Kildonan, and offer them Paul's half share if they will help Ragnvald to secure his half. Frakark, having previously arranged that her niece Margret, the daughter of Earl Hakon and Helga, should marry Earl Maddad of Athole, second cousin to David I, as his second wife, thought that Orkney might be had, with half the jarldom and all Caithness, for Margret's son Harold Maddadson, then an infant in arms. Ragnvald and Frakark then made common cause.[10] But in 1136 Paul defeated Frakark's ships in a sea fight off Tankerness in Deer Sound in Orkney, and immediately afterwards seized Jarl Ragnvald's fleet in Yell Sound in Shetland, though Ragnvald and his men escaped to Norway in merchant vessels, to return later on.[11] Meantime Olvir Rosta, Frakark's grandson, who had been stunned and nearly drowned in the sea fight at Tankerness, in which Sweyn's and Gunni's father, Olaf Hrolf's son, had aided Jarl Paul, burned Olaf alive in his home at Duncansby, Asleif, Olaf's wife, escaping only because she was absent at the time. Further, Valthiof, Sweyn's elder brother, was drowned in the roost of the West-firth, while rowing south to Jarl Paul's Yule Feast. Sweyn Asleifarson, as he was ever afterwards called, then went to Paul's Hall at Orphir to complain of Olvir Rosta. The news of his brother's death, which arrived during the feast, was considerately withheld from him, and he was greatly honoured there; but he roused the jarl's anger by slaying Sweyn Breast-rope, the jarl's forecastle-man, at Orphir, not indeed so much for the murder, as because Sweyn had fled and did not come to submit himself after it to the jarl, and so offended him.[12]
