This story is a sequel to The Siren Song trilogy. Read the first story here
The age after the war was one of the darkest times for Adagio Dazzle, Aria Blaze, and Sonata Dusk. Ever since their resurrection, they were manipulated into tricking others down a warpath that would only lead to the destruction of all three worlds. They were only freed from their curse by being defeated by The Rainbooms at the Battle of the Bands.
From there, the next seventeen years of The Dazzlings' story had them growing up from scratch, thanks to the power of a song known as the Second Life Song. Throughout this time, they reawakened their true power, fought off monsters from Euphoria and Dystopia, slaughtered the Six Euphorian Deities, and discovered that their brothers had been manipulating everything. From their resurrection, to the attack on Equestria, to the Battle of the Bands, it was all the work of Fortissimo Blast, Allegro Maelstrom, and Orchestral Chill.
A year ago, The Dazzlings, alongside their friends, had defeated the three evil Lyricans, and sent them to rot in the afterlife. From there, they ascended to Lyrican royalty, and became the Lyricans' new ruler; Queen Unity.
However, what they don't know is that an old foe, older than The Blasters, is about to resurface and throw all three worlds into armageddon, mass death and destruction of a nature so horrific that people would shudder whenever his name was even mentioned...
