It was a major shake-up for most ponies: the loss of magic from Equestria. But for Cozy Glow, it just meant swapping her enchanted stone prison for a normal ball-and-chain one. Besides, that was ten years ago. What does she care of the humbled world outside? Or that it just delivered her an uppity new cellmate?
Luster Dawn cares. A lot. It's why she's here.
(Takes place between The Last Problem and Gen 5. AU Tag because these events are probably gonna get invalidated by canon someday.)
