I talked to CK the other day, and we got some new info on some of the less mentioned dimensions.
So here's our current list of dimensions (besides the vanilla Minecraft ones):
The Void: A dimension with crystalline plants, Mycons, and terrifying monsters.
The Aether: Aetherstone islands floating in the void. Kinda like the End, but with Aetherstone islands. Also, there's Sahagan, Aerakkoa, and giant ghost chickens that are as fast as ENDERDRAGONS.
The Shadowlands: A dark and shadowy version of the Overworld.
The Veil: A dimension filled with mist.
The Maelstrom: A giant whirlpool with floating islands.
The Pinnacle: A giant mountain with storms.
The Abyss: Features unknown, but it apparently has DEMONS.
The Land of the Dead: Pretty self-explanatory - people go here when they die.
Kaiju Dimension: The 15th dimension, which is said to be inhabited by Kaiju.
For everyone who's yelling at me "You forgot the Channel and the Zone!" apparently even CK hasn't figured those out yet.
So, I'm thinking instead of having individual pages for each dimension, we just have a Dimensions page.
Anyways, that's it for today! Enjoy!
