Name:
Xion
Her real name was Serrah Fayorn

The Fallen Angel
Her nickname's origin came from her past as well as her angelic stature. Seeing as her family was part of the Order of Light, Xion was expected to live up to the idea of being 'pure' and 'innocent'. However, she became corrupted and tainted when she strayed from her path.

History:
Not much is actually known about Xion's past aside from what she's told others.. or what the head of her order knows. The simple, rather brief, rundown that is told goes like this: Xion was, originally, born into a family who was loyal to the Order of Light. Everyone within the Fayorn line was recorded to be blessed with the powers of becoming either part of the Valor class or the Wisdon class.. and every member within the Fayorn tree was recruited to close the gates. Truly an outstanding lineage.

As said earlier, the Fayorn line was famous for being part of the Valor or Wisdon class.. you could imagine the disappointment Xion's parents must have felt when they realized their eldest daughter wasn't finding her niche..her talent..her class...even her key blade Their disappointment had gotten to the point where they had begun to disregard Xion's existence, hiding her from the world, from society.. anything to avoid the risk of disgrace upon their righteous name.

Of course, just like any other human, Xion became furious with her family and appalled at their treatment. This sparked emotions that were not suited for a member of the Order of Light to possess, emotions like vengeance, fury, bitterness that all eventually led to one thought; murder. The more she was around those she shared the same blood with, the more Xion began to fantasize about their demise. Slightly frightened by the traitorous direction her mindset had taken, Xion decided it would be the best option to leave. And so she did.

Escaping into the world she was never allowed to see, it hadn't taken Xion long to end up on the border between the realms of Light and Darkness. It was there that she saw him. The leader of the Order her family was desperately fighting.. yet, unlike the normal reaction most people would have, Xion didn't feel a shred of fear.. instead, the 12 year old girl felt a far more dangerous emotion; curiosity. Apparently, the head of the order mirrored her reaction, his intrigue in the young girl was too great for him to overcome. Eventually, they became "friends" of sorts.. he taught her the ways of his organization, taking her under his wing and recreating her identity from Serrah Fayorn to Xion, The Fallen Angel. From him, Xion learned to control her key blade and her summoning class. But her new profound power didn't come risk-free. Slowly, Xion became consumed by the darkness, her "pure" ways being lost.. and her right eye changed from it's emerald green to a crimson shade.

When she was 14, Xion's power and control over her key blade was something to be feared and talked about. If it wasn't bad enough that she held a rather destructive Key, the corrupted teen also possessed the class of "Summoning", a rare trademark of the Order of Darkness. By this time, Xion's distaste and blood-thirsting attitude towards the Fayorn line had grown in magnitude, consuming every waking second she endured. It was then that, on the night of what would have been Serrah's 15 birthday, that Xion attacked.. and killed them. If it wasn't enough that she was a member of what was considered to be evil by society, the very sin she committed that night has put a large target on her back by the Order of Light.
Your thoughts on each side:
Light: "They are all cowards, too afraid to even utilize an extraordinary power! Afraid of the unknown.. I believe they should all just crawl back under their shells. Or better yet; die. Heh.. I personally wouldn't mind taking a few out."
Class:
A Summoner but in the future, will also become a Shadow
Personality
The word most people might use to describe Xion is “odd.” No, she's not your perky, constantly happy girl but is more of the withdrawn into her own mind, analyitcal type of female. Because of this, very few people actually know how to talk and hold Xion's attention with very few actually succeeding. Not helping her out in the slight, she holds quite the frightening power in her order and a rather powerful key blade. Generally speaking, Xion is very calm, solemn-looking with a distance look in her eyes, but that’s not to say that she’s unfriendly (to her comrades that is). Unlike most reserved people, she quite likes her fellow team members and getting to know them for their mind and not their looks. When she does manage to hold a conversation, Xion usually quite pleasant to be around but also is fairly awkward. Unless the other party is very good with their words, chances are there will be more than one uncomfortable pause or an abrupt subject change.

Another interesting point about Xion is that she tends to expend energy only when necessary, and is usually a lady of few unneeded actions. Under-achiever is what you may call her. Especially if she's assigned to do something; she'll only do the bare minimum. However, this isn't the case with her words; seeing as the first impression many get is a quick thinker with a sharp tongue yet who remains indifferent and emotionless. Despite this uninterested air about her, Xion has no qualms speaking her mind and unexpectedly has a short-tempered side to her as well. It is quite difficult to understand what she does and why due to her rarely showing any outward emotion and unique thinking patterns (something of which most people notice immediately).

On the note of her intelligence, Xion may appear to project an aura of "definiteness", of self-confidence. This self-confidence, sometimes mistaken for simple arrogance by the less decisive, is actually of a very specific rather than a general nature; its source lies in the specialized knowledge of the world and how she was treated as a child. When it comes to her own areas of expertise -- and trust me, Xion has several -- she will be able to tell you almost immediately everything about that certain topic, to the extent of being ridiculously precise. Yet, despite this fountain of knowledge in her, she knows this important rule; She knows what she knows, and more importantly, she knows what she doesn't know.
Strengths:
- Summons

• Chaos holds high stamina and high HP, allowing for him to attack longer with higher damage points than the other summons Xion can bring forth. Made of complete shadow, this demon easily dodges most attacks, unless they are light-driven. Chaos, once in contact with magic attacks, can copy and replicate those attacks, returning them with twice the amount of power. As for Chaos's wings, this Dark Heart can briefly fly short-distances with or without Xion in his arms as well as cause blinding "fog" through flapping them.
• Destruction holds high HP but low offensive attacks. Often, when fighting, these Dark Hearts will make duplicates of themselves before surrounding their enemy. The only way to defeat these shadow creatures is by killing all of the duplicates (there can only be 5 at a time) at once...otherwise the remaining Destruction will awake it's dead brethren through an ear-splitting shriek. Another ability it possesses is it's speed. Destruction can run at high speeds for an extended period of time, with or without Xion on it's back.
• Swarm has low HP and low offensive attacks. Probably ranking in at one of the weakest Dark Hearts Xion can summon, these annoying flying skulls multiple and fly around the enemy's head. Thats it. No attacking, no threat.. just flying and confusing the enemy.
• Imp even though frightening looking, these Dark Hearts really aren't that dangerous. They have relatively low HP but quick reaction times which means that you are only in trouble if you get close to their scythes. Their main attacks deal with slashing at their opponent with their weapons but one or two magic attacks destroy them.
• Lucifer has medium HP but high levels of offensive attacks. Some of it's notorious attacks include disappearing into shadows before reappearing, a poisonous bite and an ear-splitting howl.

Weaknesses:

• Mention of her real name
• Bad-mouthing the leader of her Order
• Challenging her in any shape or form
• Being told what she can or can not do (only the head of her Order can do this)

Romantic interest:
None
Status:
Single but being one of the few females within the Order, she is often the center of attention from the male gender.
