I'm gearing up to run Princes of the Apocalypse, but in my home setting of Generica (of which Remlia is the main country where humans live).
I've run G+ games there before, but in different sections of the country. Here's a quick image to show where exactly Eastern and Western Remlia are located on the map proper.
Also I have no idea how the scale works. At times I've described Remlia being about as big as Washington state, other times its more on par with Ontario.
