Dimension (Zen Lands)

I think it would be really fun if a new dimension called "The Zen Lands" was added that wouldn't rely on night and day but different stages of the "cycles" of that dimension, so like there could be a cycle where neutral mobs are safe and then a shift where everything becomes hostile and dark and morph into dangerous things (same concept as werewolves). There could be new biomes as well, following that same theme and at the center of the map a pond of yin and yang where you could spawn in the final boss and fight it. New ores, trees and maybe giant crystals could be added as well. A flying tameable mob would be great too! You could also add a way to channel the "zen" in the dimension and add a ton to the game. I think this would extremely fun and be a challenge to seasoned players who have already beaten the game and really have no where else to go in their worlds. This new realm would also need to be drastically harder, with netherite gear being somewhat equivalent to gold gear. This dimension would have to be totally survivable and like a second world, where as the nether is a stepping stone, this would be the next realm to conquer and live, build, mine and craft in.
