Cyn was illegally sold far younger than BMMs are allowed to be purchased — not having gone through any proper training and having no experience handling any kind of job. Suffice to say, the people who were tricked into purchasing her quickly realized their mistake, shot her in the chest several times to ‘put her down’, and threw her in a biological dump. She was saved by Tessa and given very simple tasks to do in the manor where she lived. Cyn chose her own name unlike the others who were given names by Tessa (as they were trained to do, while Cyn was not).
Unfortunately, while in the dump Cyn was infected with the solver virus, and later became the first sapient being to learn to control the abilities it gave her. Some say it was her need for vengeance that drove her to become obsessed with the virus’ strange nature, others say she had simply found her ‘calling’ working with it. At some point the disease consumed and nearly killed her, turning her into LBW (living biohazard waste). However, she managed to survive the deconstruction of her body — and with the change gained even more abilities.
Shortly after this transformation, she believed herself to be something above humans and BMMs alike and went on to kill, consume, and infect others just like the virus itself.
