The Heart Beats Still by ArgonMatrix
https://www.fimfiction.net/
In its earliest years, the Crystal Empire was no stranger to threats. Chief among these was the umbrum, a race of ancient shadow-beasts that stalked the arctic wastes. Seemingly born of pure malice, they took great pleasure in tormenting the crystal ponies—destroying their homes and breaking their spirits for fun. And as the Empire grew in both size and prominence, these attacks only became more abundant.
Princess Amore did everything in her power to keep the umbrum at bay. And by using her magic in combination with the Crystal Heart, she was largely successful. But against such overwhelming and unrelenting darkness, even she was pushed to her limits. And the umbrum were growing more cunning by the day. Eventually, something had to give.
Now faced with the darkest days the Crystal Empire has yet seen, Princess Amore will be put to the ultimate test. Against a hatred as old as the wind, can the love of a single pony really make a difference?
