Hi Experts- this is the Sky Altar (11x16), one of those maps that you'll need to catch a lift to and from. And then when you arrive you'll say something about how it sounded bigger in the brochure. Anyway, try not to fall off.
Your alternate versions of this map are Cloudy and Propless! I figured this Cloudy variant would cover a lot of bases if you didn't like the pleasant partly cloudy background- just about anything could be under that fog, even other sky islands. And, you know, propless, because if we're talking versatility then you know I have to get rid of all extra bits that might make you dismiss this map at a glance. Feel free to tell your players to imagine better props in place of the altar!
