What my parents take me for: Introduction

I am a normal 13 year old girl, and my parents don't love me. My father sells drugs, and my mother, well, she was a prostitute. I decide to leave my home and go join a guild far away. I stumble upon a guild in a town called Magnolia. They all persuade me to join the guild, all do I have no powers. What will the other members think of me? Who am I really?
