Wow, that last part was really surprising, and it hit hard. In the thumbnail I didn't notice it, so it was a bit of a sad shock. Nice work! You conveyed what I believe you were trying to convey fantastically
People seem to like the idea of poor little Luna getting banished to the moon and gradually turning evil after years of isolation. What they fail to realise is that Luna was corrupted by jealousy, not loneliness.
I see things like this, and all I can think is how sad it must have been for Luna up there alone for 1,000 years. I suppose this one does kind of hit that point on the head, but still it's flat out amazing that Luna didn't go completely insane from loneliness.
