The Aether is Minecraft's heaven. There's flying whales, flying pigs, clouds that shoot you off of platforms, and different materials that you can make tools out of. It never turns night, but it turns a little darker if it's raining in the normal world. There's also boss castles that you can fight and stuff. There's also a certain material that you can eat, I've heard. But, this would obviously require a lot of roll backs, because people are going to get greedy with the resources.
