Coerthas

Coerthas is a region in the northern part of the fantasy world of Eorzea, featured in Final Fantasy XIV. It is characterized by cold, snow-covered landscapes and rugged mountain terrain. The region’s political and cultural center is the fortress-city of Ishgard, a long-standing seat of religious and political authority that plays a central role in the region’s history and in the game's main storyline.

Geography and subregions are defined by highland plateaus and mountain ranges. The most notable populated area is Ishgard, situated on a high plateau in the Coerthas Central Highlands. The Coerthas Western Highlands include Fortemps Keep, the hold of House Fortemps and a key ally to Ishgard. The surrounding landscape features blizzards, icy ridges, and snowfields, with the eastern edge bordering Mor Dhona, a separate region that serves as a hub for adventurers and contains ancient ruins and milestones in the broader lore.

History and significance within the game revolve largely around the Dragonsong War, a long-running conflict between Ishgard and dragonkind. This war shapes much of Coerthas’ political structure and its architectural style. The region also houses ancient ruins and relics tied to megadruadic histories within the broader narrative. In later developments, players exploring Coerthas uncover the outcomes of the war and the lingering tensions between humans and dragons, as well as the region’s enduring strategic importance in the wider world of Eorzea.
