I read the books over and over as a child and knew the anime diverged from them but holy shit none of that sounds like the story I’m familiar with except the name jasmine and the fact that there are mountains
Edit: I skimmed/searched the linked page and that description doesn’t actually sound accurate to the show as a whole, so maybe that’s just a singular episode?
Edit 2: It sounds like the thing OP was looking for wasn’t Deltora Quest after all, which makes me extremely skeptical your description has any truth to it at all.
It definitely reads like an ai hallucination, lol
