The deep dimension

It would be a fourth dimension that would be meant to be horrifying you only get it through lighting the portal in the deep dark and imagine it just being completely dark always like if you bring a night vision potion is straight up just doesn't work like you actually see animation where it cracks glows blue and disappears and all the mobs would be way more tougher and more scary looking and there would be different variance affordance based off the scrapped wardens photos and then there would be a faction called the dark ones that worship the warden and you could fight them and stuff and they will naturally fight with villagers and illagers and they will always attempt to get to the overworld also there would be an invincible boss that needs to be trapped but would eventually escape that would be so large you could never see the full thing in one photo.
