Well this is kinda off topic, but you sparked my curiosity, and I hope this is something knew because everyone loves it when a new member puts something irrelevant. So, as you just said there is no Pack-a-Punch on the moon, but theres also more than one moon than just Earth's. Titan, one of Saturn's moons actually matches the surroundings of Shangri-La perfectly. "The thick atmosphere is orange due to a dense organonitrogen haze." "It is the only natural satellite known to have a dense atmosphere,[9] and the only object other than Earth where clear evidence of stable bodies of surface liquid has been found." Seems like a perfect paradise. And get this, there is even a specific area on Titan known as Shangri-La. It also states that there are areas of higher land in Shangri-La, as seen on the map. Seems like a little too much of a coincidence. But yeah, let's hope I'm on to something.
