There is certainly no further record of Alan pursuing military actions against Óláfr, which could be evidence that Alan came to terms with an arrangement between the two competing branches of the Crovan dynasty. The pact between Óláfr and Guðrøðr Dond turned out to be short-lived. According to the saga, when the fleet left for Norway in the Spring, it clashed with the Kintyremen before sailing northward to , where it ousted a certain Þórmóðr Þórkelsson from the island. A few weeks after the fleet left the region for Orkney, the saga reports that Páll was slain in the by Guðrøðr Dond. According the "Chronicle of Mann" and the "Chronicle of Lanercost", Guðrøðr Dond established himself in the Hebrides but was later killed, with the former account locating his death on . In any event, it is apparent that it was only after Guðrøðr Dond's demise that Óláfr was only able to secure the full tenure of kingship. Óláfr went on to rule the realm until his death. Upon the homeward return of the Norwegians, the saga declares that Hákon's "honours had been won" as a result of the expedition, and states that Hákon himself heartily thanked the men for their service overseas. The operation seems to mark a turning point in the history of the Kingdom of the Isles. Although the kings that ruled the realm before Rǫgnvaldr could afford to ignore Norwegian royal authority, it is apparent that those who ruled after him required a closer relationship with the Norwegian Crown. Even though the Norwegians acclaimed the conclusion of the campaign, its only lasting achievement was Óláfr's restoration. The Scots too may have welcomed this outcome, considering the consolidation of the Crovan dynasty after years of chaos, and Óláfr's familial relationship with Fearchar, Alexander's principal northern protégé. Nevertheless, the campaign itself may have been the gravest crisis faced by the Scots since the English invasion of Scotland in 1216. Although Scottish sources fail to note the campaign of 1230, its magnitude is revealed by English sources such as the "Chronicle of Lanercost", and the thirteenth-century "Annales de Dunstaplia", with the latter reporting that the campaigning Norwegians and Islesmen were only overcome with much labour after they had invaded Scotland and Mann and inflicted considerable casualties.
