Gaia/ IX

It consists of four major continents: the Mist Continent, the Outer Continent, the Lost Continent, and the Forgotten Continent. The vast majority of people in Gaia live on the Mist Continent, and very few travel to, or are even aware of, the other three continents that make up their world, largely because the main mode of transport, airships, run on mist, and mist only exists on the Mist Continent, meaning they cannot fly to other continents.
