Scene from Ch. 50 of The Sirens Remorse
 
“Ora… Oratoria!?!” Adagio gasped.
 
With a roll of the eyes, “Ya! And I’ve been looking everywhere for you since you tried to take over the pony kingdom. I had to get myself exiled just to follow you, you know!? I mean it wasn’t hard getting that Starswirl alone and all, but after that… ha…” she swayed her head back in forth in regret of the life she lead after the fact, “Doesn’t matter anymore I guess. After all we still are Cappella’s pack… the last sirens to survive that is.” she answered as if offended that Adagio was so slow to remember her.
 
“Whose Oratoria?” Aria questioned squinting hard as if trying to see why she was so familiar to Adagio.
 
“Oratoria… how? How did you….?” Dazzle gasped again.
 
Instead of an answer, the turquoise human instead walked up to her until she was just a breath away. In clear eye sight of Twilight, Sonata, and Aria did she envelop the golden siren in a hug to which the recipient had no words for and simply received it. She simply attached herself painlessly to the matriarch and remained still as if the act itself was life sustaining. Adagio seemed paralyzed at the admittance of who the person was, though no one else knew what the name meant or who Oratoria was. There was a quick spark between the two as their once harmonious magical fields of her home pod clicked together in a euphoric haze of placidity in the zone of chaos. For sirens to sing in harmony, they had to work hard with new members to sync together otherwise their musical enchantments were off key and clashed with each other. It would take months to practice as one and be able to feed off their prey for life giving power. Yet when it happened, they were as close as close could be besides physically, Matriarchs often called it a Choir Frequency. No family of sirens were alike to another who lived on another coast or across the world, each had a subtle adjustment to the ears to detect. To feel the sensation once more was a very sobering moment and one that proved to her that this girl was no threat hiding away in plain sight.
