[Note: I orginally sent this to just Jeff, but it's got some stuff in it that everyone should read.] Hmm. After playing with the combined maps of Qaiyore & Elyria, I get a pole-to-pole distance of 2696 pixels, or 13,480 miles, giving a polar circumference of 26,960 miles and a radius of 4290.8 miles, closer to 108% of Earth's radius than 110%. This map suggests some interesting things. First, the Elyrian continent extends towards the poles more than is shown. Second, the Elyrian continent wraps around the globe enough that you could reach it by sailing northwest from Hisaria, as well as northeast from Celpalar. Anyway, I've posted the merged map to the Website. Be warned, it's over 6 MB as a .gif file, so you'll have to click on the link. Aside from some cropping, marking the equator, and marking the approximate region of the Avaerean Islands, I haven't made any changes.
