I'm just curious. I might consider creating my character as a kind of hybrid of the two- kind of like a fallen angel when you look at them, but not a fallen angel. A mixed race of human-zith hybrid.
I could picture my character, Mika (I haven't put up a character sheet yet so I can still change the race), having some internal struggle with her beastial impulsive side and her rational, more human side. She'd wonder about the taste of human flesh, or have to restrain herself whenever she feels the urge to eat, say, a friend?
I'm just curious about it ^^ I'd say her mother would be a zith and her father a human- he could have been a slave, or something. Or maybe her mum was a zith away from her species.
Could it be done?
