Something terrible is coming to Equestria, to bring a little balance to all this peace and harmony. Mephistopheles and Carryion have escaped Tartarus, seeking vengeance on the alicorns who bound them. With Discord still maddened by the demon's curse, will our heroes be able to repel this ancient evil, about whom so little is known? (This is a direct sequel to Seeking Secrets. Strongly recommended you read that first, though I think this one is written better. Or don't. I'm a description, not a cop.)
