Edit: Hey look, past the new audio player is a new map! check that out! Huge thanks to the map guy for this and all future maps! Do note the main things I discuss in this episode: the east wet nature of the mountains and the rivers, the central plateau, and the north south nature of the Iberian Kingdoms. Portugal is not so weird in this company.
Follow up edit: I went ahead nd made some new maps myself, in high quality large format PDFs so you can zoom. They are linked from the second and third maps. That first one still looks great tho doesn't it? Oh and there are Frankia maps, same deal, third and fourth.
