Damien Knight is a creature of the moon, and ruler of the moon goddesses kind. Rough, Ruthless and Heartless are some of the words that are used to describe this rugged man.

Bill Cipher was the most mysterious pirate that sailed the seas. No one know his past. No one knew where he came from, he had just arrived one day. He knew the sea better then any other pirate. Every nook, every crany. He knew it all. But yet he longed for something that had been taken from him. Dipper was a siren. Not a normal one. He was an outcast at his home. An orphaned siren was about as good as a cup to the other sirens. Dipper only had one thing from his parents, a singing voice that could drive even a siren to insanity. Which is why he never sang around anyone. Never.

You've heard the legend of the Siren. Greek Mythology has them as horrid beasts, who murder the sailors who hear there song. But have you ever heard how the legend became, who started it. Why it started. Now you will as the original takes the stage. Disclaimer: Rick Riodarn owns everything except OC's and plot. The Trials of Apollo never happen, but Leo does still die and has not come back.
