Aethepor
You look down from the plane window, you're no longer over the Pacific ocean now, but rather vast areas of grassland; welcome to Aethepor.
Aethepor is a large island located far from the west coasts of the United States and Canada. Often nicknamed as the "Steampunk Country" due to steam power still being prevalent; about 45% of the machinery in Aethepor is steam powered, 10% of that machinery is new.
The island is dominated by grasslands with small and large river streams going through the grasslands. Exceptions being the area surrounding Mount Carre and Mount Gate, which is mostly forest.
