So, my fantasy world is in a birch world at the end of time, trapped inside the event horizon of a supermassive black hole. It may as well be a demon world from 40k. There's no sun, and space itself has already been ripped apart at the seams so long ago that maps and navigation tools are almost useless. The only thing holding the world together is far future technology, and even then, only barely. There are forests that literally go on forever, caverns that literally go on forever, etc, because the "world" is infinite, but old and breaking.
Space is just busted except in the really general. Up is an endless firmament of burning plasma, down is endless darkness, and to every direction is a landscape that looks normal, but the laws of physics break down closer and closer to total lethality the farther you go from the core. It's also easy to get permanently trapped in spacial folds, which people just call labyrinths, mazes, or dungeons. Winding up in the backrooms is a legit problem.
What I'm trying to say is, at some point the world is already so bad that it can't be fucked up anymore.
Other notable anecdotes about the setting:
>Humans went extinct billions of years ago, and were replicated by aliens called the beautiful ones based on knowledge they gained from coming across the voyager space probe, and subsequent simulations of what old earth was like
>Unironically, the fathers of humanity are considered to be Jimmy Carter & Kurt Waldheim because of this
>Humans are capable of magic because the beautiful ones were too eldritch too conceive of life that didn't have psionic powers
>Humans destroyed the beautiful ones in a climactic genocide
>Over the course of billions of years, all species either bodily ascend to a higher plane of existence, or linger in hedonism because they don't want to risk ego death
>The beautiful ones were basically billions of years of cowardly civilization runoff that couldn't or wouldn't ascend, just evil, insane hedonists
