I am pretty sure I did not do that, you kind of made a wild leap. What I said does not matter to Alignment.thank you for making my point about why darksun & every other non-fr/gh clone would only made worse by suggesting the similarity with a thing so deeply linked to FR's lore. You literally named one plane & effectively referenced a second one that are not part of eberron's cosmology both of which require a very different spin on alignment to describe khyber. It's the sort of innocent question that forces a long "what khyber is not" tangent rather than "here's what khyber is" simple description
I said Khyber is like the Underdark plus it has traits of the Abyss and Hell (More the Aybss then Hell). Those planes are not in Eberron, but Khyber has traits from them. Namely the seemingly endless nature, being home to a bunch of pocket realities that tend to be awful, and being the source of most of Eberron’s fiends and some of it’s biggest baddest villains.
This describes Khyber fine.
