Description: I had a pretty good life. They called me Spit Shine, I worked in the palace, cleaning this, doing that. Hell, I even got to talk to the Princess, and learned all sorts of interesting stuff. It was stimulating, prestigious, and hey, call me weird, but I liked the work.
Shame I was also secretly a changeling infiltrator with a name too annoying to pronounce in polite society trying to observe and potentially subvert your nation state.
I mean, these things happen.
