"Mad Scientist" Zhen and Jingzi

Zhen and her oldest creation, companion made from the face of her biological sister Jingzi and the bodies of their fellow sister wives.
Zhen is strongly rumoured to be at least a thousand years old, her face resembles that of a favoured concubine from a long gone dynasty who has fallen out of favour and has found the secret to a long life through practicing and obsessively studying all kinds of sciences and magic from around the world while in isolation and despair.

She specializes in gene editing, surgery, ancient protosciences and folk medicine which she all incorporates with modern science... pushing the boundaries of morality and ethics one creation at a time.
