The Mane 6 did it. They have defeated Nightmare Moon after her 1000 year return. But Nightmare Moon was not destroyed. Instead she's been split away from her good self Luna. Instead of being sentenced for execution, Celestia instead opts to sentence Nightmare Moon a punishment that'll be worse than death for her crimes. The former queen of the moon will spent the rest of her eternity with dragons... as their own pet. Will she get used to this punishment?

This story is an AU Friendship Is magic Part 2, where Nightmare Moon was instead split into herself and Princess Luna.
