On the villiager migration thing, have any villiagers decided to stick around just to see what happens? What does happen?
(I'm gonna answer everything else later I'm busy rn but this is a good one)
They know how Endings go, it's part of knowing how the world works for them, so no one really bother. But they have campfire stories. The details varies, but the gist goes like this:
There's a people who loved their perfect world so much, they live in constant fear of its End. When that happens, because it always happens, they stayed with their world, until all the beauty has been picked away by the Enderman and an Ender Dragon appears.
Some says she took pity on them, trapped by their obsession, and taught them how to find beauty in other worlds, and they became the first wandering traders. Some says she tried to trapped them like the rest of the enderman on her island, but they mimicked her form and flew away with her egg, for now they have truly seen everything their world has to offer. Some says they slayed her and freed the End, and brought the secrets of that dimension to the other villagers. The ending of the story changes a lot, depending on what kind of lesson the storyteller is trying to teach.
But Citizens of the End is just a story. The ender dragon is just an animal. No one, villager or illager, has seen an ender dragon and come back alive. Certainly there wasn't a village or mansion full of dragon mimics who learned that the universe is capable of lying.
