Not a lot of time today or tonight (playing D&D, actually), but I did manage to play around with Google Earth and GIMP some more. I'm slowly beginning to figure out both of them, with an emphasis on slowly. Here, I just used the Google Earth Placemark tool to make Valz and place. Then, I exported the map to a JPEG and added the "Arms of Orum" textbox. Simple, I know, but I am taking baby steps here. I'd like to find a way to make the Arms label stand out a little better against the blue ocean background.
I almost added several cities to the map, especially to al-Andalus, but I ran aground coming up with names. I couldn't decide how Spanish they should sound and didn't have time to do a lot of research. I don't want to name a city something that translates into "bird vomit."
