The Living Doll
Manne-Kyn are a Genestruct Race developed to serve the noble elite of Nouveau Planète Bordeaux. Their original purpose was to serve and entertain without question, and to alleviate the stress of their masters by a specialized process of Mesmer called Massage de l'âme, mind massage, in which they use their powers to put their master within a trance so that they can explore their mind and help them overcome obstacles of stress.
They were freed by their Harle-Kyn cousins during a revolution on their world, and now live as free members of society. They have since renamed the world to Nouvelle Planète Bordeaux, switching the planetary title to the feminine to reflect the matriarchal rule of the Harle-Kyn
Manne-Kyn were designed to be highly morally responsible, which is why they have issues lying. One of the modifications they have results in them having a partial face blindness—they have a delayed amygdala response to faces and so a delayed response to processing a face—their obsession with fashion is because the presentation of their bodies is the foremost aspect of recognizing each other.
Manne-Kyn were not originally designed for indulgence or gratification. They were designed to be the next step of a more empathetic, socially-capable creature. An indigo child that would hopefully deliver intelligent life into a new age.
Unfortunately the research was taken over by government and corporate interest, and bastardized. Manne-Kyn still posess that underlying design, but have no guidance on how to use it.
