Nearly - Headless Nick. He has a lot of knowledge about Hogwarts' history. In a fanfic focused on the Chamber of Secrets, he could be the one to remember an old legend or forgotten fact that helps Harry and his friends. He could also be in danger of being permanently petrified since he's already a ghost, which would add an interesting twist.
Harry Potter is of course very important. He's the one who has to face the danger in the Chamber. Hermione Granger is important too, as she uses her intelligence to help solve the mystery. Ron Weasley stands by Harry's side throughout. And then there's Ginny Weasley who is directly involved in the opening of the Chamber unknowingly.
