In another record, also dated 16 May, John authorised his seneschals, governors, and bailiffs in Ireland to come to Rǫgnvaldr's aid in the event that his territory was threatened by "' or others", since Rǫgnvaldr had bound himself to do the same against John's own enemies. The record of "'" or Vikings in this order may refer to the Norwegian raiders, like those who plundered the Isles in 1210. This particular source reveals that, not only was Rǫgnvaldr protected by John, but that he was also obligated to defend John's interests in the Irish Sea region. As such, Rǫgnvaldr's security was enhanced by English assistance, and John's influence was extended over the Isles at the expense of the Scots.
