I didn't download a map though, I made one by making a superflat world that's literally just air
So the nether and end are normal
I also gave myself the standard Skyblock island with a tree, water bucket, and lava bucket, as well as a singular potato and carrot, and one dripstone to slightly reduce my reliance on the wandering trader
There's also a singular budding amethyst block next to the end portal which is a couple hundred blocks away from my starting island
