Koridan is a country in the Six Seas region of Elara. It is bordered on the north by Danara, the east by the Jenari Waste, the south by Aldemir and the west by the Apenic Sea. It features Mrala Bay (a large bay on its western side), several small islands, and numerous rivers including the Eternal River which begins far to the east, but ends its journey in Koridan by emptying into Mrala Bay. Koridan is mostly forest and plain, with two mountain ranges located south of Mrala Bay and in its northeast corner separating parts of the country from the Jenari Waste. The climate is warm-temperate.
