Aether

Aether is a dimension consisting of huge and small floating islands with bright blue sky and clouds everywhere. Aether is like the opposite of the Nether, the Nether is a closed dimension, it is covered with bedrock layer at both the bottom part and the top part, while the Aether does not have any bedrock layer at all. Clouds are located below the islands and sometimes above the islands.

This dimension is made from aquamarine-colored grasses and blue-colored dirts with blue stones too. The dimension is similar to the End except with no actual main center island or central island. If you fall off the edge of an island in the Aether dimension, you will be sent into the Overworld dimension back.

Surviving here is not difficult nor easy. Because some of the animals here are neutral, they can attack you if you provoked them, examples of neutral animals are flying goats, sky bear, and Aether fishes. They are the main source of food here, they drop raw foods that you can cook to restore your hunger bar.

Coals can't be found here, but you can use the woods of the trees as a fuel or you can smelt the woods into charcoals. Neodymium is a common ore here, you can find it almost everywhere and it's as common as coal ores. Neodymium can be used to create attraction pistons, a type of piston that you can use to pull any block (max: 12 blocks) in front of it and push any block in front of it.

Monsters are very rare here, they usually spawn in dark places, but because the average light level here is very high and it's always daytime here, monsters are very hard to find. They drop weapons that you can use to kill other hostile mobs. Caves are much much brighter compared to the caves in the Overworld, the caves are almost completely devoid of monsters or any type of mobs.

If you try to sleep here, the bed will not explode, instead you will get a message saying "You cannot sleep here". So it's different to other dimensions, because in other dimensions, sleeping there will usually cause the bed to explode with a really high blast power. So beds are useless here.

To enter the dimension, you will need to make a vertical rectangle glowstone frame, it must be at least 4 blocks wide and 5 blocks high. Put a water inside the frame and the portal will open, enter the portal and you will be sent into the Aether dimension.
