The Warring States of NPF - Soul Hunters Discussion

If I may be so bold, especially this late in the game, I would like to throw my hat in as the stereotypical Not Exactly Evil Person Who Wants To Kill The Hero Over Some Dumb Thing That Happened In School.

Name: Sarah Sayalle
Age: 21
Gender: Female
Eyes: Brown
Hair: Black and long, the center part of it is braided, but the rest hangs free
Height: 5'4"
Usually wearing: When she doesn't expect a fight, she just goes around in whatever she feels like wearing, usually something very overpriced. However, in preparation for a fight, she dons a red and yellow suit recommended to her by an old friend...the same old friend she now wants to take the soul of.
Affiliated with: nobody.
Enemies: The One.
Allies: Several private detectives she pays.
Soul Crystals: One full with the soul Astrabelle, and one empty.
Purpose in Life: Revenge!
Brief Bio: Although rich, Sarah was never the most popular girl in school. This may be due to the fact that she was one of the two biggest RP geeks in town. No prizes for guessing who the other one was. The two of them had many campaigns together, and even sparred with swords on occasion. Then came graduation day, and the two were to go their separate ways. One last dungeon run was scheduled. Courtney, being the wily DM she was, threw everything she had at Sarah's party. Monsters, mages, and of course THE TRAP. As Sarah was playing a barbarian, she was the one to fall into THE TRAP. She emerged enraged, and vowed to sooner or later get revenge. At first she only meant to get Our Hero back on the D&D grid, but soon Sarah became obsessed with her complete destruction, preferably face-to-face. Around that time, the mega-corporation Xenarc, which used souls in various ways for money, threw away a soul crystal they found useless. While wandering the street, plotting her revenge, Sarah saw the soul crystal laying in a Dumpster. Upon contact with it, she knew she had found her secret weapon. Now, to find the elusive Courtney...

Powers:
Fusion with Astrabelle: Sarah can fuse with Astrabelle to increase her skill in military strategy (useless, no troops), magic, and swordfighting. However, she cannot use Astrabelle's full power, as Astrabelle is a pure soul, and Sarah has been corrupted by her obsession. When not in fusion, Sarah is an ordinary mortal with no other powers.
Light Healing: A low-level cure spell.
Soul Freeze: A low-level cold spell that chills the soul of the enemy.
Sense Familiar: Astrabelle can sense souls that she once knew, whether in a soul crystal or reincarnated into a new life.
Sunlight Blade: The swordfighting style Astrabelle was proficient in when alive, it bears resemblance to that of Western fencing, but emphasizes more body motion.

Tools of the Trade:
The Suit: Although it doesn't actually do anything magical, when Sarah wears it into combat she moves quicker and strikes harder because she gets pumped up.
The Sword: A simple Chinese longsword taken from the family collection. This is what Sarah trained with, and is also close enough to Astrabelle's native weapon for proficiency. It is usually worn with The Suit, and comes with its matching scabbard.
The Soul: Astrabelle was a guerilla leader in some other realm. She and her rebels overthrew two wizardly despots, but the more powerful of the two cursed her soul to never pass into the afterlife. Thus, soul crystal. As stated before, Astrabelle's soul is pure.
The Cell: What rich girl wouldn't be complete without a cell phone? She uses this to keep in touch with the detectives searching for her nemesis, and also to call them for aid when she's in really deep trouble.

Strengths: Strong will, soul fusion ability, really freaking rich
Weaknesses: Weak when unfused, certifiably insane, has no damn idea what she's getting herself into

...well, that's Sarah, version three. Completely the opposite of the previous RP incarnations of Sarah, who were both The Good Guys. So, what do you think, sirs and mortal enemy?
