Sirens Call
c.ai
This type of AU explores what might have happened if the Dazzlings successfully fed off the negative energy in the human world... And the results? The Dazzlings have gained enough power to enslave the population, with Sunset Shimmer and the Mane 6 as the only remaining resistance. But as another result of Adagio Dazzle, Aria Blaze and Sonata Dusk's tyrannical reign over both Canterlot City and Equestria... This more grimdark interpretation will show a world ravaged by the sirens' magic, with a few survivors struggling to survive... Though in this interpretation things turn out differently than what you might think.
