Abilities
Mind link. Tristia and Gaudia are always connected and able to speak through their minds. If needed, one can draw the other into their mind, but this leaves their body completely limp and unable to move.

Soul Blade
Tristia wields a twinblade made of shadows that she can summon at will. It lasts for as long as she holds it and she cannot damage herself with it as the blades just pass through her, meaning she can do moves normally impossible for the physical equivalent. With 7 seconds of channeling, she can imbue her twinblade with a mod of her choice for 20 seconds.

Mods:
Density: The blades turn pitch black and gain density, making the blades strike harder and recovering from strikes slower.

Cauterizing: The blades turn red and become extremely hot, cauterizing the wound upon impact. While this stops the wound from bleeding, it is extremely painful. Hits to vital points are Non-fatal (at least not right away), but all wounds hurt far more than normal

Ghost Blade: The blade ignores armor and skin, causing only internal damage. However the blade cannot strike organs or main arteries or veins.


Personal History
Tristia's first memory was a containment tube. Until Gaudia was 16, it was the only place she ever knew. However she knew what the testers said outside of her tube. She was a failure. A disappointment. She wouldn't amount to anything. It was cruel and unfair, never being able to defend herself. Never being able to prove what she was capable of.

Then they let her out of the tube. Not for long, but they let her train and test her new skills. The test...didn't go so well. With the first flourish of the twinblade she managed to nearly cut her leg off, only a small amount of muscle keeping it on. They quickly sedated her and put her back in the tube. Again, she began hearing that she was a failure and she got angry. Not only that, but all memories of joy or happiness, like first finding out she would have her own room (or rather, that Gaudia would). Gaudia....where was she. They had never let them see each other. Yet Tristia knew somehow that she existed. The tests continued and Tristia improved.

3 years later, Tristia was floating in her tube, when gunshots rang out through the room, and the researchers inside were killed. Soldiers in blue vests cleared the room before using hand signals to go to the next one. Who were they? Someone who seemed to be in charge turned to her tube. "We'll be back for you" he said before he and his men moved on through the room. Gaudia! She didn't know where she was, but from the researchers talking, she knew that she was somewhere in the facility and that her powers were still unrefined. She had to do...something. Suddenly through her concern, a connection blossomed between their minds. Tristia immediately imagined taking Gaudia and sheltering her with her body. Suddenly she heard Gaudia in her mind. She was also squirming frightfully. 'Calm yourself' she thought...

The next day, the two of them were introduced to their rescuers. They were the MCU, the law of the unseen world. Were the two girls angels? No. So they were human? Yes. How did they get those wings? Gaudia shrugged. Tristia winced. Then Tristia felt Gaudia through their connection. Wait Tristia knew? Of course. And Gaudia didn't? No, clearly they each knew things the other didn't.

The next few years saw the both of them training and testing the limits of their abilities. Most of the modifications Gaudia knew were due to tristia having been taught them at the lab. The two developed a dependence on each other. Tristia needed Gaudia to balance her inherently cynical nature and to stay her hand when killing was not an option. They quickly gained a reputation for as mercenaries and assassins. As a team, they worked expertly together and decided that is they were to make their way in the universe, it ought to be with each other. "After all," pointed out Tristia, "what other life have we known?"
