Another aspect of the assembly may have concerned the remarkable rising power of Amlaíb Cúarán in Ireland. Edgar may have wished to not only rein in men such as Maccus and Gofraid, but prevent them—and the Scots and Cumbrians—from affiliating themselves with Amlaíb Cúarán, and recognising the latter's authority in the Irish Sea region. Another factor concerning Edgar, and his Scottish and Cumbrian counterparts, may have been the stability of the northern English frontier. For example, a certain Thored Gunnerson is recorded to have ravaged Westmorland in 966, an action that may have been undertaken by the English in the context of a response to Cumbrian southward expansion. Although the Scottish invasion of Cumbrian and English territory unleashed after Cináed's inauguration could have been intended to tackle Cumbrian opposition, another possibility is that the campaign could have been executed as a way to counter any occupation of Cumbrian territories by Thored.
