Blocks in the Sky

We've all played SkyBlock in Minecraft, right? If you haven't, well, sucks to suck... So what if you were actually living in SkyBlock, where you're a part of a thriving civilization up there in the sky, which no problems, cares, or worries whatsoever? What if that civilization began to fall? What if your string of islands got invaded, then tangled into a war with another string of islands? Why am I asking so many questions? ANSWER ME ANSWER MEEEEE!
