The land is accessible by climbing a beanstalk or through a stairway (& suspended wooden walkways) that travels up through the mountains. The place is dangerous not just because of the denizens who inhabit it, but due to the fact that here is very little solid ground. Much of the footing is obscured by clouds, or made up of clouds, meaning there is no footing at all in these spots--not for a long way down! The Realm of the Sun lies far above the Land of the Clouds.
