oh BOY do I have a negative arc
Before everything, she was a little withdrawn. She felt out of place in the world around her, and depended almost entirely on her sister, shaping her personality around their connection. She was studious and a little snobbish. When alone, she felt panicked and aimless with no one to anchor her. Art and books and music could help, but the anxiety of missing her sister remained. She didn't know who she was without someone to lean on. Part of her hated herself for it - she felt weak, secondary, but she could never seem to break away. Somehow, attachment felt safer.
After everything, she was raw ambition. She was rampant paranoia. She was a furious kind of murder, doing dark deeds with flamboyance to show off her vast skill. She'd depended on the wrong people for too long, and who she was around them had poisoned her. At long last, she broke free of dependency and became a leader… but it was too late to be a good one. The years of training and hardship and ascension had hardened her. The months of doing everything on her own had made her unable to delegate and trust those around her. The endless days of darkness had made her angry and hungry for more, always more.
During everything, she was scared. Her sister was gone, and she was frantic without her anchor. She tried to latch onto someone kind; this person was taken from her by another, darker force. By circumstance more than by choice, she came to depend on her mentor, the woman who made her strong and taught her to never stop thirsting for greater things. She learned how to defend and how to kill, how to fight and how to run. She learned how to stay quiet when it was necessary. She learned how to follow orders blindly. She grew very skilled at this craft. But her mentor's lessons of ambition stuck, brushing against her old loathing of dependency. And so a seed was planted.
During everything, she grew hungry. She attached herself to another person, wrongly believing that he was not her anchor because she no longer needed one. She followed him blindly. It was with him that she again saw her sister, for the first time in many years. The sight of her didn't fill her with joy as she had expected, but fear. She was afraid that she would become someone soft and reserved again, someone who was always second, never strong. In her confusion, she lashed out, drawing even further from her sister and who she used to be.
During everything, she fell in love with the wrong woman. Her lover stroked her ego, whispering promises of greatness to come if she would just rise up for once. She was about to - and then she was returned to her old life abruptly, too soon for anything to come of her resolve. Forced into a world she no longer knew and associated with an irrational fear of her old self, she lashed out again. She cut ties with every anchor she had, leaving her in her frantic, aimless state. Holding on to her ambition, she fought hard to rise to the top of the heap. Once she made it, paranoia kicked in. Doubt spiked everything around her. Her choices were made of fear, and it was turning people against her. It really was no surprise when they rose against her.
The world around her is a mess of pity and pride. Her sister feels great sadness for who she has become; her mentor and new anchors feel pride at her skill and loyalty. For a time, her sister tries to save her. Eventually, her sister tries to stop her.
She doesn't really believe in anything now. She used to believe in innovation and learning. She used to believe in the power of art and beauty to affect positive change in the world. During everything, she lost that. Then she believed in loyalty, power, strength, and fear. She believed in fighting for a place at the table, and using your loyalty and skill to earn every scrap they gave you. And when she finally reached all of her goals, she realized that there was nothing left for her here. And so she believes in holding her power tightly and never letting it go - but she has no reasoning behind this, other than her terror to be powerless again.
i wrote that VERY dramatically OH boy but hey it's nothing if not a negative arc (her name is Natalie, she's lovely, and she ends up as the villain). Um… enjoy, I suppose !!
