Sunset coughed up water and gasped. She was dizzy and couldn't comprehend what was happening. All she knew was that there were a lot of blurry looking people looming over her and muffled shouting. She felt out of breath and weak, something that angered her almost immediately. She did not like to feel weak and vulnerable.

She felt someone tap her shoulder and lift her head up. A boy with freckles helped her sit up and he patted her back. Instantly, she hacked up loads of water. Her ears popped and she heard them ring from the pressure of water being in them. People jumped back in shock as the water came spitting out her mouth.

"Sunset Shimmer!" she sort of heard Rainbow Dash call.

Sunset would've responded but she got an odd taste in her mouth. A taste she knew was acid from her stomach. She choked and clamped her hands over her mouth. Everyone stood back as Big Macintosh helped to her feet and rushed her to the bathroom.

Throwing up.

That's all she did for five minutes straight. And she didn't even eat breakfast that morning. Outside the girls' bathroom in the indoor pool, Applejack's brother waited patiently, not at all alarmed by what was happening. Vinyl and Lyra stood beside him anxiously while the others went to fetch the P.E. teacher.

"That was amazing, Big Mac!" Rainbow Dash told him gratefully. "You saved her life!"

The boy nodded and grinned humbly.

"Don't think it too heroic. You would've done the same if you knew CPR."

Rainbow colored slightly. "Y-Yeah, you're right."

Flash sighed as he tried to process what was going on here. He and Soarin were shaken up by the whole thing. Sunset had been out for nearly a whole minute before Mac got her to breath. That minute could've been the deciding moment of her being alive and dead. It scared the hell out of them.

Sunset came teetering out the bathroom and Mac took hold of her arm. She needed rest and something warm to wear was his immediate thought as he felt her cold skin brush his hand. Octavia came in with the P.E. teacher. Their coach was looking pale and lost. He could lose his job for this.

"What's going on?!" he yelled, his voice slightly shaky.

Octavia pointed to Sunset and Big Macintosh. "Sunset nearly drowned, but Big Macintosh saved her!"

The P.E. teacher went white in the face completely. This was bad.

"Bring her to the nurse's office. Young man, you'll be rewarded."

He hurried them out of the indoor pool area and dismissed class early. No one was paying any attention to the fact that it was Trixie who caused the whole thing...

Adagio sensed it.

It was wavering in short burst of energy.

It was the magic. The power and energy was struggling to become stronger. But it faltered and became weak again, a small reminder in the back of her head making its presence noticeable only at a glance. Aria and Sonata stopped their arguing and tilted their heads in the direction of the pulsing magic.

It was too short of a burst to know exactly where it was coming from.

Aria gritted her teeth and stomped her foot on the pavement.

"It's as if it's mocking us!"

Sonata frowned slightly. She didn't like this game the magic seemed to be playing.

Adagio didn't say anything. She squinted her eyes and hummed. She felt it coming from a certain place...but she wasn't sure if she was correct. It definitely was somewhere there.

"Lets go home," she announced and stood up.

"What?!" Aria cried in outrage.

She stood up abruptly and the chair teetered behind her.

"Didn't you just feel that power? We can go and follow it!"

"That power faltered. We're back at square one, Aria," Adagio told her calmly.

"We should've moved faster!" she yelled.

Adagio stared at her for a long time. Aria had a short temper, but never with her. To see her going crazy over this made Adagio realize how power hungry she was. She was deprived of it and wanted it back more than anything. This was foolish of her. Adagio slapped her in the face.

Both Aria and Sonata stood there stunned.

"You're being stupid. The last time we had power, it was taken away from us. You should be grateful that your life wasn't taken as well. We have to be careful about how we get it back. We can't just stumble blindly into whatever may have it. Besides, it could involve those girls..."

As soon as she said that it sprouted an idea in her head. Those girls...That's it.

She hesitated before turning to head home.

"Lets go."

Sonata slowly followed and Aria stayed back a little before trudging behind. This wasn't an thing for her to get over. She wanted power. But Adagio was stalling. Fire set in her eyes, she watched their leader walk ahead, drilling holes into the back of her head angrily.

Twilight skimmed through her books three hours later and sighed. There were Serpent Sirens, Transylvanian Sirens, and Tartarian Sirens, all of whom she was certain Sunset was not. She frowned. This was hard. She could see that Sunset could most likely be a Draconneqi Hybrid Siren, but wasn't sure. Not much was known about them.

Twilight read more about them and found that it was all repetitive, some sources even plagiarized from another. Sirens can sing, live in the water, feed on souls and/or emotion, other stuff. She was just about to close the book when she saw the word 'jewel'. Snapping the book back open she leaned forward wide eyed.

JEWELS

Every Siren has a jewel on their neck. If this jewel were to be removed, the Siren will lose its ability to feed and die. Every jewel is color coded to its specific classification of Siren:

Blue signifies the Serpent Sirens

Purple signifies the Mermare Sirens

Red signifies the Draconneqi Hybrid Sirens

Green signifies the Soul Sirens

Orange signifies the Seahorse Sirens

Turquoise signifies the Transylvanian Sirens

Yellow signifies the Tartarian Sirens

*See page 984

Twilight was right! Sunset was the most mysterious one of them all, the Draconneqi Hybrid Siren. So that means Adagio and the others were once those creatures as well. Twilight noticed small writing at the bottom of the chart. Squinting, she read the words.

*See page 984

Curious, she turned the pages all the way to the designated page and glanced at it. It was more about the jewels, of course.

Once a jewel is separated from the Siren all magical properties from the creature are immediately stored into the jewel. If the jewel were to be broken in the process, the power is to be divided between each shard. Creaturologists have found evidence of it being a sport of earlier ponies to kill Sirens for their precious life giving source. Seeing it as valuable to their pockets, they hunted them down. The jewels would be crushed into fine powder and served in wine to royal families to symbolize their strength.

In this process, however, early Equestrians had become aware of the jewels' magical properties.

Ponylore states that there was once a mare who came across a group of sailors jumping and fussing by the coast of the Alicorn Ocean at night. She asked them what was wrong and saw that they were arguing over who gets what fraction of the treasured jewel. The mare, who had never seen such a beautiful thing, reached out to touch it while they weren't looking. Suddenly, the power of the jewel's shard surged out and attached itself to her.

One moment, she was a pony. The next, a Siren. In absolute surprise and fear, the sailors ran away and the mare disappeared into the ocean. Legend says, she was last seen by that ocean shore. But there have been claims that some have seen a mare slip into the water and turn into the enchanting creature and vanish. The Siren turned mare has now been named the Demi Siren.

Whether or not this ponylore is true, it is indeed a possible thing. Creaturologists have found that normal Sirens can only live with a complete jewel. When the jewel is fractured, the Sirens tended to die. However, the shards showed strong pulses of energy whenever a living organism came close to it and a sort of magnetic field was created between the two. This, the Creaturologists theorize, could indicate the strange occurrence that a fractured jewel could possibly attach itself to another organism.

Twilight paused.

A shard attaching itself to something other than a Siren...Wasn't that what that shard did with Sunset? Was Sunset a Demi Siren? Twilight turned through the book in search of anything pertaining to a Demi Siren. But she found nothing. There was absolutely nothing on Demi Sirens...

So now she figured out what type of Siren her companion was, and that happened to be the most mysterious type of them all. And now she's finding out she's half Siren? So she technically is still a human??

First, Sunset Shimmer was a unicorn.

Then a she demon.

Then she became a human.

Now she's half Siren?!

What the hell was up with her changing species?!?! Was she going to become a Griffon next?!?!?!?!?! Twilight huffed and slammed the book shut. Great. Now how was she supposed to help Sunset Shimmer? She was back to square one. She doesn't know a thing about anything.

Leaning back against the clutter of books around her she hoped Sunset was doing well.
