All good. The world when she was human is just normal Earth, though only thing special is when coming back eventually is that her eyes can things that weren't there before. So it's a hidden world that most people don't see. As for the other, just looks similar to normal Earth too. 1/3

Same sky, sun, moon, and plants, just less modern buildings and roads. Though it's mostly populated with humans and dragons, both feral but talking and anthro, while having other races and anthro creatures. 2/3
