This is Ethran - a world that is stuck in a geosynchronous orbit with its larger twin, and which is slowly being robbed it of its atmosphere. The ocean is all but frozen, and the only habitable places to be found are situated in the iris of Ethran's eye, around the blackened volcanic mass of its pupil.
Drawn in (and rendered directly from) Campaign Cartographer 3+, using the Herwin Wielink template. The coastline was partially hand drawn, and partially taken from a Fractal Terrains 3 fantasy world. This image is in its original rendered state (give or take that I had to reduce it to 25% to upload it). There are no map notes or specifications for this drawing, because it was drawn by me to go with an unpublished book and two or three months before I joined the guild.
