A struggling young adult finds herself in Tartarus as the nefarious Cozy Glow. If she wants to go out and freely explore all of Equestria with her villainous buddies... she was first going to have to change this evil filly's future.
Cozy Glow had decided to run away to the far off arctic lands that housed the Crystal Empire. Doing this was a dire mistake that'd last for thousands of years.
