*Real quick, I made up a lot of stuff here since the internet wasn't telling me much about Sirens so yeah. Some of it is true, some of it made up.*

Twilight buried her nose in her books. It was during the whole huge celebration Pinkie Pie threw in, well, celebration of her coming back. Everypony in Equestria was there and it was going on for hours. Twilight was not at all interested in the party and had escaped when she saw the chance. She wanted to research the Sirens. She needed to know for Sunset's sake.

Reading from the many books she had on them she completely drowned out the booming sounds of music coming from the castle courtyard. Of course, with her basic knowledge on the Sirens already, she came across some things she knew already.

Sirens are any of several aquatic beings that of the Sirenidae family in Northern Equestrian waters. Their nesting grounds are mainly in the Equine Sea, the Mareiterranean Sea , and the Alicorn Ocean. They have external gills, small forelimbs, and no hind legs. Just a tail. The more Mythical approach was that a Siren was one of a female group of creatures that lured stallions to their deaths in the water.

Trying to see Sunset do that made her feel hot and angry. The image in her head was not at all nice to her, as it was Sunset seducing a stallion. Well! That's not happening! She shook her head and read on.

2b. noun; a female who sings with enchanting sweetness.

Sunset's voice was not at all sweet or enchanting. It had a loud soulful ring to it that would fill your heart up with warmth. No sugar, all spice. Fluttershy would make a better Siren than her in that aspect.

Twilight tilted her head as she read the pages of her book.

Sirens feed off a multitude of things from souls to emotions. It all depends on the type of Siren. As stated before, there are several types. Each species has a certain characteristic and behavior that differentiates it from the Sirenidae family.

SOUL SIRENS

One of the most common type of Siren, this particular creature feeds off of souls. Through singing, it sucks its prey dry of its inner life force, leaving the carcass behind. Averaging about 3,000 corpses by shorelines every year, it's not an accurate estimate. Many of the corpses are taken in by underwater creatures as food. There are definitely a lot more dead than being accounted for due to this fact.

Soul Sirens are the basis for all anatomical sketches and descriptions in textbooks. They are the first Sirens to ever appear, descending from Salamanders from the Everfree forest. The first ever recorded sighting of a Soul Siren was in 736 B.L. (B.L. Means Before Luna, referring to before her 1,000 year banishment to the moon). Soul Siren territory lingers around the mouth of the Mareiterranean Sea near Saddle Arabia's coast line.

MERMARE SIRENS

Recognized as mares with fins, they often cause destructive ends to the lives of sailor ponies. Voices as light as the great pony heaven above and faces as gentle as the waves, they entrance sailors. Not causing the damage themselves to the ships the sailors stand upon, they do, however, cause them to sink. By singing sweet words of encouragement to jump in and join them, they lure sailors into the water only to be mauled to death.

Those who do not follow the others into the water are told to steer the ship toward the rocks with songs of sweet melodies. There is not an accurate count of how many die of Mermare encounters due to other reasons of death at sea(dehydration, lack of sleep, food deprivation, etc.) They were discovered around 698 B.L.

Twilight paused.

These two types of Sirens she needed to think. Was Sunset either one of these? She didn't think so. Sunset had not turned into a mermare, or rather mermaid. Nor did she seem to be a Soul Siren. She looked like one, yes, but the problem was that she had wings. Wings was not something Soul Sirens had.

She moved on.

SEAHORSE SIRENS

This type of Siren is often mistaken as regular ponies among modern Equestrians. With the same features as normal ponies, they fit well into society. However, there are ways to identify them from Equestrians. They come as earth ponies always and tend to have sharp, pointed ears. On their 'flank' is a generic symbol. Usually they are sea related. A common Siren 'cutie mark' is a fish.

Unlike its Soul Siren and Mermare kin, Seahorse Sirens do not feed off of ponies. Their way of feeding is through the water. Seahorse Sirens cannot be dry for more than 4 hours. They often are seen swimming in water. If a Seahorse Siren is not near an open body of water, however, they usually will have bottled water with them to drink.

Seahorse Sirens are very friendly and can learn the ways of modern Equestrians very easily. Speaking the language does not come very naturally, so they are often perceived as being slow. Seahorses have been around since 701 B.L.

DRACONNEQI HYBRID SIRENS

These Draconneqi hybrids are the descendants of both the Salamander and ancient Draconneqi. Appearing to be much like Soul Sirens, they are generally mistaken as such by creaturologists(that's not a real thing, but lets just say it is. It's Equestria). What distinguishes them are the large wings they possess and the long manes. Most Sirens do not have long manes. It is believed that they appear during full moons and bask in the light as a source of food. Not much is known about these mysterious creatures since they hide away.

Whether or not they are an aquatic type of Siren species is debatable. Presumably, they were around by 541B.L.

This spiked Twilight's interest. Not much was known of this type. And they had wings and long manes, much like what she saw Sunset become. Sunset could easily be on e of them. Randomly, an image of Discord and Sunset came into her head. What if Discord was Sunset's father?

No! Oh my god!

Twilight glanced down at the locket she wore around her neck. Obviously, she was a pony before she was a human and now a Siren. Discord is not at all related to her.

So far, she got through four different types of Sirens. She decided to take a break from all this studying. The others would wonder where she went after drifting off from the obscenely loud party outside. Twilight reluctantly closed the book and walked out the library with Sirens on her mind.

Author's Notes:

So, pertaining to my readers. In the Group "Sunset Shimmer", there is a blogging thing called #FebFIMFanficLove that one of the members posted up. Because it's the month of Love and whatnot, Piquo Pie, the member who had posted it, would like peeps to share something they love about MLP that they normally wouldn't share. It's like a confession.

I suggest you guys do it and post what you like about MLP and how you got into it and all that jazz. Some peeps might even inspire you to create wonderful literature like this one. Who knows? You could be the next TheNewYorkBrony if you try! I'll leave the link below for those of you who want to share a blog and see the guidelines.
