Placeholder, and uploading so I can show my work. The distance between the Shadow Academy and the Dark Ascent is based on the Wiki entry for Arx listing its diameter as 13,000km and the diagonal measurement of the map of Arx (which I assume is the circumference of the planet) being 2203 px, converting to 18.54km/pixel. The distance between the centres of the two icons was 375.6px, or 6963.624km. Note: I don't expect this to have any impact whatsoever on judging, but since I put the work in to figure all this out, I was damn well going to share it. :P
