C1
Child of SD and R1. The one who really ruined everything for humanity?
Psychological Profile
Her father emphasized to her the importance of excellence. He always pushed her to be elite. He married the most powerful family in the world and that's what he expects from his progeny, continued and evergrowing power.
Being strong, powerful, elite, was her whole purpose, and she developed into the most powerful necromancer the world had ever seen.
Her father was always away, fighting or otherwise. Though her mother fawned over him he didn't seem to care as much about her as much as her power.
C1 accepted this as normal, her father is an ambitious man who will save the world, and they are willing tools to help him do it. And giving her little love, and even philandering, was normal for the type of world conquering alpha man that he was. She can only hope to get close to him by being more useful to him, to bribe him for affection with her success and power.
She was proud of being the best necromancer in the world, surpassing her little sister who was a close rival to her. Her pride was visible and sometimes exhibited itself in cringeworthy ways, but she really valued that her father compared the two and found her better.
Interestingly, in comparing C1 and C2, R1 the mother semi-favored C2 who was the more chill of the two, who seemed to take being second best to C1 in stride, a bit as a reaction to how C1 held the father's favor for C1 over C2. So this was another point of resentment that C1 had for C2.
As an aside on C2: C2 however, developed a "don't care" attitude as a defense mechanism against her father's favoritism and C1's low level bullying. She was rather fine to just follow C1's lead and wanted her to see that she was not jealous of her and was fine with being second best, and that she was not a threat to her and that she just wanted C1 to be happy.
C1 is therefore broken psychologically when she realizes that that is not true. Her father did love, just not her, but another family, a Sica family of his mistress.
In fact the child he loved the most is one of the weakest, with no necromancy power at all.
This was a fundamental betrayal of her entire life and she reacts harshly. She curses her father for being weak and sees the worst in his intentions.
