The mercenary and the princess

Freezing was given the assignment to write a short, quick, fake mythology for his science class. Based off the Greek stories about how we the constellations came to be. Freezing took it a bit too far and wrote a 6 page story on a medieval timed constellation story. It's the tale about a mercenary, called the silhouette murderer, who wants revenge and the princess who's just a pawn to her father. Once they meet they join forces and together they solve their most important problem. Killing the king.
