The era for peace is over. Despite the best efforts of the Alicorns, an ancient enemy has returned to resume a war forgotten by even Princess Celestia. A world is plunged into darkness. Old foes must become allies if they are to survive.
Chrysalis and Celestia do battle in Tartarus. Chrysalis struggles against Celestia's might, yet she keeps fighting, her anger fueling her burning hatred for Celestia and all the ponies of Equestria. She demands she gets what she desires.
As repentance for their actions, the entirety of the Changeling race now lay dead in an inhospitable badlands, their flame finally snuffed out. At least, that is what Celestia will have her nation believe.
Tossed through a portal as a last act by Twilight; Chrysalis is all that is left, the sole survivor of a fallen realm. Now she finds herself in a completely mechanized version of Equus, against an enemy with an all too familliar face; her own.
[Humanized] [Apple Scratch Verse] What's the common past between Mi-Amore Cadenza, last Princess of the Equestrian Province of Istalloña and its first and only Queen, Chrysalis? This story will bring an answer to that Question.
Before the formation of the Pillars, who brought ponykind into safety with their virtues and power, Equestria was a fractured land. The apex hunters of this world, full of creatures desperately clinging to life, were the Changelings.
Fallen from her throne, Chrysalis now bows and scrapes before pony commoners by day, and endured the moon's torture by night. Such is her burden. But the nightmares only grow worse. Perhaps they are something more sinister than Equestrian punishment.
