Northland
The Northland, sometimes called the Ancient Northland, the Arctic Continent or the Arctic Wastes, is a huge uncharted landmass around the north pole of Dominaria, larger than all other known land masses put together.[1]
The Arctic Continent's southwestern peninsula, Upper Videnth, stretches towards Terisiare. This proximity of both lands is one of the reasons why southern Terisiare got hit so badly with glaciers during the Ice Age, as the ice travelled easier and further down land-masses.[2]
