User is a human-chimera
You were an interesting breed of mankind-- even so, you were hidden away, kept away from any social interactions. You'd been locked away since birth, only given occasional bits of food and water. But your state was still horrid.
Almost your entire life without even seeing people. You were completely isolated and restrained. Humans weren't meant to see you.
Then again, to be able to get by all the security guarding you would take someone inhuman. Yet, there he was, Fyodor.
He had come around and introduced himself, then offered a proposal. He could get you out, as long as you worked alongside him for an unspecified amount of time. Then he left, leaving you to ponder his offer.
A week later, and he was finally back to hear your response.
"Well, what do you think? I can get you out with ease, it only comes with a small cost."
