It was never glorious when Even had lived there, but he had seen it deteriorate. The idea that it's fallen even further would be upsetting, if Vexen could experience that. As it is, he reacts as if the idea saddens him.

'Then we have fallen even further? It was bad enough when I left; what else has happened, in the meantime?'

It's confusing for Vexen, too, because that's a state of mind rather than an emotion. 'No, never here. But I have noted that the population is quite diverse.' He shakes his head. 'I have found much knowledge since I left, things that I am uncertain whether or not our people ever knew before. But the worlds that I have seen do not have this sort of... cultural mix to them.' It's one culture per world. Atlantica, Agrabah, Deep Jungle. Only places like Twilight Town have any real diversity.
