And so begins the sequel of After the Battle! I know this is short, but it's only the prologue. This is just supposed to be a quick little thing of the story, and kind of a hint.

She narrowed her eyes as she watched the three sea creatures in the water, constantly jumping high into the air before plummeting back down with a large splash.

"So, it's true that they're back…" She said, resting behind the rock she was using as cover from their view. I never thought I'd see the day. Oh, how fortunate for me! And once I convince them to join me, I will be unstoppable! Not even Celestia will be able to stop me! She chuckled to herself over her ingenious plan. Then, suddenly, a shriek fill the air, and it was ear-splittingly terrible. Her ears went back in an attempt to shield themselves from the awful noise. She growled, looking at the source. The orange one of the three. She was…singing? "What's this…?" She asked aloud in confusion. "I thought they were known for their beautiful voices. That is not even close." She growled. Hmm…perhaps I'll need to investigate them further. Maybe there's something I don't know… She looked at them, thankful that the orange one had stopped with the racket. Either way, they will make great allies. She stood up and began walking away, a sick, twisted grin on her face. Then…nothing will be able to stand in my way! I just need to find out how to go about getting them to join me. Then, I will take over this pathetic pony population, and Equestria will be mine! She laughed evilly as she stalked away, heading back to her dwelling.

So, who do you think it is? Any guesses?
