Due to Rau being a Cu sith and having been raised in a realm of death, she always had a hard time grasping the weight of life and was unable to sympathize with her father who was always mourning the dead.
Because of this Rau has two personas
The Facade: The mask of innocent emotional display that she wears around others in order to fit in
The Reality: The cold emotionless person underneath who struggles with the concept of morality and the value of life itself

I got this artpiece a LONG time ago but entirely forgot to upload it for some reason
Anyways, this lovely display of duality was done by my friend and artist
