Great new chapters! Glad to see this thread is still here. I hope it hasn't run out of steam while the site was down.
In Diamond Tiara's story, I liked how casually routine Climax and Mort's use of the bodies is, and how the magic preservation treatment became popular. I wonder if that'll inspire any mares to suicide (either themselves or pressuring a friend) to preserve their looks while they're in their prime. And poor Silver Spoon: at least she can still cuddle Diamond. Friendship is tragic!
For Young Luna's story, the shift in perspective was interesting. Seeing someone else get first crack at the cold ones opens up a lot of story possibilities. I wonder if any of the unicorns or alicorns at the castle ever temporarily remove the resin to use her corpse.
I'd love to make another chapter suggestion, but I don't want to hog the queue or anything if my Fluttershy idea is already in the works.
