Koldor is a relatively small continent in the northern hemisphere of Ith\'Meireun. The extreme northern regions of the continent are locked under polar ice, and this is generally regarded as the boundary of the continent. It is unknown how far the land continues under the ice. Ancient maps of the Noghiri Empire indicate that the continent breaks up into island clusters near the pole, but inconsistencies between maps bring this into question.
The total land mass of Koldor is approximately the same as the Continental United States of America.
