The Destroying Protector

Vorlianth The Eternal was the only dragon of his world Xavius and he only knew how to destroy. Taking lives of another was natural for him until he was 1025 years old. It was then he grew tired of killing and he now seeks a purpose in his long life. The goddess of eternal youth Hebe granted him an offer when he was 1724 years old: He shall be transported into another World, but as a human! In return he has to protect a girl, who is vital for the goddess. Will he accept the offer and start to protect? This is my first fiction, it will contain gore and sexual content. Furthermore is english not my native language, which is why I am practicing it by writing a story. Please point out mistakes and enjoy. Also the main character might be OP (but you could have guessed that already :P )
