Okay, so I have now laid out the setting of the RPG as I have decided. 

The Vilayet Sea, a central inland sea ruled by the Hyrkanians and Turanians, and littered with pirates, islands of mystery, and many a trade route. The Road of Kings, the greatest and longest trade route of this time, meets the Vilayet sea at its western shore in the city of Aghrapur and then continues eastwards from its eastern shores. This is the center of the world during the Hyborian Age, equal ways from the far east as it is from Aquilonia.

So, anyone interested?

Or are we going to hear only crickets?
