Well...an Greco-African...
...servant/overseer with the Dark Triad/Tetrad of personality traits (Narcissism, Machiavellianism, Psychopathy, and Sadism) who uses her fellow servants (to the point where she is given the name of a great monster), to gain influence/power and respect from their lord...launches a program to train others in assassination...inflicts psychological terror on multiple protagonists...winds up with power over the lord...kills him and his wife (along with the fiance of a main character) while they are on a diplomatic mission...before the grieving character puts a blade through them.
The ideas I am trying to express are the personality traits themselves, as well as the concept of a person inflicting others with pain only so they can gain power and control of them. As for why "Greco-African" - this character is based on a character from a game with Dark Elves, and one of the main cultures here is a sort of Greece-Egypt land.
*Blushes in embarrassment as I have no clue how to make this character, this antagonist, less offensive*
Other characters include: A Leonardo da Vinci-like scholar who, before an incident of shapeshifting, was going to be the "medicine man" of his tribe. (Body dysphoria & Natural Philosophy)...a woman, child of the "Pharaoh," who broke traditions to save her brother...an "undead" monster made of mold (going off of the idea that we all have certain things that can drive us insane under exposure to certain environmental problems...it is the "something in the water" or the "lead drinks drank by early rulers")...a mute "wild" child and efforts to allow them some semblance of normality...a "gypsy"...Gwion (A much darker take on the origins of Taliesin, highly cynical but not without redeeming qualities...a bard and assassin)...A transgendered "fox" and two pirates based on the relationship between 3 Chinese pirates in history...a jolly "necromancer" who is more of a doctor/mortician (because most "necromancers" were the ones who prepared bodies for the afterlife, not those who brought the dead back to life. Closest thing was spirit mediumship)...Greek Heroes cursed to appear as undead...
While not gory, this is intended to touch several ideas gradually.
