Rinaldo Gandolfi is the greatest benefactor of the Belmont Clan. He created the Whip of Alchemy, which became the Vampire Killer Whip, and gave it to Leon Belmont, which was passed down for generations. He also created many of the artifacts and magical items that are found in Dracula's Castle. After his death at the hands of Mathias Cronqvist, he became known as the Poltergeist King and bound his spirit to Dracula's Castle. For centuries, he continued his role in aiding those who wanted to defeat the Lord of the Castle.
