This is Miltia Sarl. She's a Synth, created by Sheyeng Mariwaan Labs at the request of a wealthy businessman. When birthed, she was found to be defective by SM standards and ordered to be disposed of by incineration. The technicians in charge of disposal instead took pity on her, and spirited her out of the facility by posing her as a completed production Synth on her way to delivery. Miltia soon found herself living in a Free-Synth colony within the Cave-Grove system of Landover, where she would be safe from Sheyeng Mariwaan agents attempting to reclaim her. While very intelligent to begin with, Miltia was taught numerous skills by her new brothers and sisters, and soon became an active and contributing member of the Free-Synth movement, and the Cave-Grove Alliance as a whole.
