Did you guys know that the Aether used to be in Minecraft? You guys may be thinking like "Is Minecraftyu crazy? the Aether was never real!" but let me tell you that there is a dimension that was in Minecraft Indev (I think) that is like the Aether. The Aether like dimension that was in Indev was the Sky Dimension (I found out about this dimension though a few YouTube videos). The Sky Dimension is a dimension that you could only access though sleeping, but you would get there by random chance. The Sky Dimension has grass, stone, trees, chickens (I think), mushrooms, and maybe ores. Hostile mobs do not spawn in the Sky Dimension. The Sky Dimension was removed, but then redesigned and re-added back to the game as the End, and yes the Sky Dimension was redesigned to be the End.
