Der Aufstieg

Victoria Reiss, a princess of a prosperous empire framed for the murder of her father. One day, after rotting away in a prison cell of a supermax institution, a mysterious benefactor gave her a key. It took at a while for the whole complex to notice that she was gone, and by that time, she had been long gone, escaped aboard a ship heading somewhere. Surviving on the goodwill of the captain onboard, she hails as a stowaway with a fake name of Christa Lorentz. The ship came upon a storm on the North Atlantic sea, well on its way to the Central States. A stray plank knocked her unconscious, and she woke up upon an unknown island. Immediately after gaining consciousness, a vision violated her mind. Sour Vintage. Somewhere she had to go.

At least, that is what she claims to be. Perhaps there's more to her story.
