King Sombra has seized control of most of Equus, and even with every kingdom joining the fight they stand no chance against the mighty stallion who calls himself a god. Every enemy defeated becomes another member of his grand crystal army, and only one mare has the power to stop him. The only problem is she wants nothing to do with it.

This is an Amory Wars crossover, but you don't need to know the story for context. I wrote it to stand on its own. Loosely inspired by the King Sombra AU from the show.
