According to TheFanlistings.org, a fanlisting is a web clique that lists fans of a particular subject. Unlike most web cliques, a person does not need a web site in order to join. Fans from around the world submit their information and are then listed to show their love for the subject.
This fanlisting is dedicated to Julius Belmont of the Castlevania: Aria of Sorrow fame. If you want to know more about the character, take a look around the site - the fanlisting is part of a shrine dedicated to him.
