I have written two versions of this story: One is a humanized version (the original) and the other is a ponified version. (The story works even better in the setting of Equestria) I'm not going to describe much of it because it is a short story and anything more than the short description may spoil it, however I would like to explain why the two different versions have different endings. I find Equestria an idealized world, where everything is tied up in neat little bows, (like many imaginary) whereas the human world is a lot more twisted and not as neat and tidy, so I have made the endings different to suit each setting.

Crystal Comet has done something in the past that cost many lives and wishes to find some means to escape it.
Princess Celestia has to deal with keeping Equestria under control as a possible threat is resurfaced.
Stanley has to come to terms that his new life may not be worth the struggle.
Lightning seeks to protect his kind: flame-ponies.
Queen Blanca wants a dry-season palace.
