Long ago, Equestria was in a golden age. Each race did its part to make the world a better place, and all bowed to the immortal god-rulers, the King and Queen. As time wore on, gentle leadership turned into tyranny, and the King and Queen eventually turned their backs on the denizens for reasons unknown. Several decades of decay, including the first real armed conflict Equestria had ever seen, passed. The once great country seemed to be on the verge of disaster, and yet the rulers still refused to use their great magic to help.

The young Princesses, Celestia and Luna, have their lives taken out from under them when a group of extremists and traitors seize the throne from their parents. With their magical abilities weakened, they, along with several newfound friends; a young human heir, his advisor and a pegasus filly seek out to forge a new alliance with the people of Equestria, and to put a stop to the chaos before it begins.

The princesses and all of her friends have died. What does Princess Twilight Sparkle live for now?
