the chronicler Orderic Vitalis indicates that Mann was devastated to point of being a virtual desert by the time Magnús appeared on the scene. The warring itself may have been related to the aforesaid factional struggles between Guðrøðr's sons. Although it is possible that it was Magnús who actually forced Domnall from the Isles, the fact the chronicle makes no mention of Domnall during the recorded conflict on Mann may be evidence that he had lost control of the island by then. Within the year, the same source records the arrival of Magnús himself, which could suggest that it was Ingimundr's slaying, at the hands of the Islesmen, that had incited Magnús to take matters into his own hands. Magnús' takeover of the Isles is colourfully depicted in the chronicle, and several mediaeval Scandinavian sources, such as the early thirteenth-century Morkinskinna, Fagrskinna, Orkneyinga saga, and Magnúss saga berfœtts within the early thirteenth-century saga-compilation Heimskringla. As the Norwegian fleet descended upon the Isles, the latter source specifies that Lǫgmaðr set himself to defend the ("Northern Islands"), a term that likely refers to the Outer Hebrides. A particular verse of poetry in Morkinskinna, attributed to the contemporary skald Gísl Illugason, describes Lǫgmaðr as "" ("Prince of Uist", or "Lord of Uist"). This title not only appears to corroborate Lǫgmaðr's authority in the northern Isles, but could also indicate that he was primarily based on Uist as well. At several points in the history of the Isles, the realm endured periods of fragmentation between rival factions. Whether the references to Lǫgmaðr in the north are evidence of a similarly partitioned kingdom is unknown. The Norwegian subjugation of the Isles, and subsequent capture of Lǫgmaðr, are recounted by several sources. For instance, Orkneyinga saga states as much; whilst Morkinskinna further specifies that Lǫgmaðr fled southwards and out to sea, as Magnús' fleet advanced, only to be captured and kept in the Norwegian king's company for some time afterwards. Having overwintered in Isles, Magnús left for Norway in the summer, only to make his return nearly four years later, in 1102 or 1103. Once re-established on Mann, Magnús entered into an alliance with Ua Briain, formalised through the marriage between Magnús's young son, Sigurðr, and Ua Briain's daughter, Bjaðmunjo. Magnús, therefore, appears to have intended for Sigurðr to rule over his recently-won territories. Unfortunately for Ua Briain, and his long-term ambitions in Ireland and the
