Equestria is a smog covered hellscape. King Sombra's wicked grandson, King Bosha, rules with an iron hoof. Nopony accomplishes anything, hope is but a passing fancy, and death rules with just as much ruthlessness and vigor as Bosha. Blood seeps from sewers underground, stallions work in horrific conditions and mares are confined to the home. But worse is the departure of Princesses Celestia and Luna, who put themselves into exile hundreds of years before. Things look bleak. However, the power of another group of sisters could just be the key to saving them all.
