Welcome to the world of Tarmae. In all, there are four continents, named simply for the direction they lay in on the world map.
Now, Siren Song is currently planned to take place within the Western Continent alone. As such, while I may add more maps, this map is the most important. The others would be more for your reference. The story begins at that little ship you can see just off of Inna's Cove. Things aren't quite to scale, but the three cities you can see are the capitals.
