Poignant, ethereal, beautiful... seriously amazing piece. I love the descriptions and the perspective. I have a story a little bit like this (or at least, this reminded me of it) called "The Path to Infinity and Nothing", but yours has a very different ending (mine doesn't end yet). Gotta Favourite this story. It's exquisite with just a touch of creepy. How she just... fades away. Even if it is kind of metaphorical. Or not. Either way I love it.
