It's nearly a thousand years after the events of My Little Pony: Friendship Is Magic. Princess Twilight Sparkle, or rather QUEEN Twilight Sparkle, is all grown up, has gone into Full Royalty, and is one of Equestria's leaders. But being immortal comes with a cost, as she figures out. Her mortal friends have all died, and now she is only left with the company of Flurry Heart, Hope Moore, Starlight Glimmer, and her husband, Flash Sentry. But with Evil Sombra rising once again, she is left to face the darkness by herself. Can she do it...or will she give in to the raging Midnight Sparkle of her dreaded past?
