OC list! Honestly, this goes in order of creation, but it's more of "goes in order of bad-flankery."
UPDATE
"Jhera" has been changed to "Delphinium" to match his cutie mark and to follow the general rule that the rest of the Flower family follows. Sorry if I confuse anypony

As Future Kleft, he let his emotions get the best of him, and his Fye was smashed long enough to cause mental harm. After the incident with the Fye, Kleft has been rendered unable to show any sort of emotions or feelings to a certain extent. When it was healed fully, Kleft met up with an old friend who soon after became his lover. Using Snow's ability of Essence magic, he cast off his fye and entered the power of Essence instead. Sadly, this cast off also resulted in him being exiled from Lunar Island, and he is no longer allowed to return to his place of birth.

LOCATIONS
Name: Lunar Island
Physical Description: Lunar Island rests on the southwestern part of Equestria, off the coast and in the waters. Due to it's odd location, the sun never touches it, but the moon will rise high in the sky and is clearly visible. In this location, the moon doesn't give as much light as the sun, but it gives more light than it would any other part of Equestria.
Social Description: The native ponies of Lunar Island are all unicorns. When things with Equestria began getting ugly, Lunar Island made the hard decision to split and wipe themselves off the map. Due to their lack of sunlight, their version of "daytime" is while the moon is high in the sky. The Lunar Ponies' government is led by Chancellor Mathiss, a very old and wise unicorn who's family has led the island for centuries. The Lunar Ponies are skilled in the works on psychology, and have created an emotional barrier known as the Fye that allows them to extent their magic past normal unicorns. Although, if this Fye is ever broken, such as when the pony loses their temper to the extreme, it can cause emotional and physical damage to the breaker. This is because of all the emotions and feelings they have walled up behind this barrier, which could cause many problems if let go to flood out all at once.
Affiliations: Lunar Island is very secretive, and has no real affiliations.
NOTE
This is not every OC I have ever made. Some of them I play to use once and only once, so I saw no need to place them in here.
