i don't know how to explain it exactly but my favorite thing about the end is something about it feels existentially horrifying in a way the other two dimensions don't, and the emptiness is a huge part of why
the other two dimensions are full of ruins and treasure and echoes of long-dead civilizations that had values and purpose and goals they were trying to achieve. there's a real sense that they're ruins now because they were destroyed, or abandoned, or taken over
the end cities don't feel like that. they aren't even ruins. they're just empty. it feels less like their inhabitants fled or died out and more like they just...stopped
