Not bad. You're the second person to write a Frostpunk/MLP crossover that I've seen. Your off to an okay start. And I'm guessing World's End is the name of your city in the game. Fitting. Mine's Snowbourne. I'm curious to see how this plays out.

Thank you for the feedback! Funny thing is that the name of the city was a place holder since im actually pretty bad with names but when submiting it I realized I hadnt changed it so I guess I'm just gonna have to go along with it.

By the symptoms, Celestia died of Tuberculosis
Then again, it's your story. I was just pointing it out.
Love the read. It's a good start and set up to why the world is freezing.

You have a great start to this story, please don't let it die, there are very few stories related to this topic

"I have grave news Luna"
"W-what is it dearest sister?"
"I’m dying."

Literally grave news indeed.
...I'll see myself out.

Good premise so far.

Although I had expected Celestia would spend the day making plans with Luna how to save her little ponies, after she said "No. I must explain why this is happening before I... depart."
It seems now Luna has to figure something out on her own (or maybe ask Twilight).
