This story is a sequel to Twilight Daylight: The Cold War
After returning to reality from Narmeelah's Time Pocket, Dawn and a handful of creatures witnessed a battle for magic with Twilight "Arcadia Nova" Sparkle, Saviour of Psera at the helm. Psera's military was damaged, ponies now lie dead in the streets of Equestria. Dawn was too late to put a stop to a war between her and the rest of the world.
Twilight Sparkle, the most powerful pony to ever exist, the creator of spells, mistress of the elements, and role model to millions, now awaits her sentencing for crimes against ponykind.
But a threat looms over Equus. A threat that Dawn herself has seen. A threat that will destroy all of ponykind unless Arcadia Nova is released. They won't do it. Only she remains.
But what is she to do? With her father, King Shimmering Madun dead, and her mother Queen Arcadia betraying the world, Dawn is left in limbo alone. Her home untrustworthy for her safety and Equestria refusing to engage with anything to do with Arcadia...
How can she save Equus?
