One of the 100th

You happen to be Clarke Griffin's younger sister. You were hidden from everyone most of your life and it wasn't until another younger sibling was found that they thoroughly searched every apartment on The Ark. They locked you up, but your mother lived because they needed her and you were one of the privileged families. Unaware of your father's death, or that your sister is on the drop ship, you are sent down on Earth. Every minute on Earth has been a fight. Until you meet commander Lexa.
