In 1130, the the revolt of Oengus of Moray is successful, and Orcadian Norse control spreads to the Scottish mainland. From its beachhead in Moray, this grows into a sprawling Norse-Gaelic state, "Megenland", so called because most of its settlers have come from the Kingdom of the Isles, and they see it as the mainland. Its Gaelic mormaer, based in Elgin and later in Aberdeen, owes fealty to the king of Norway.
To the south is a compact but populous Scots-speaking rump kingdom, "Scotland", centered on the Edinburgh-Glasgow axis. Its survival depends not only on French support, but also on the rivalry between England and Norway with respect to Megenland, where it provides a convenient buffer. As England's power grows, the intra-British realpolitik shifts, and Scotland grows closer to Megenland. However, no reunion is ever attempted, as the two areas have drifted apart culturally and linguistically.
