Justin Steele was a Ravenclaw student at Hogwarts School of Witchcraft and Wizardry in the 1990s. In 1996, he stood at the entrance to Horace Slughorn's compartment on the Hogwarts Express, ensuring that only those who had received an invitation were allowed to enter. Later that same term, he, Daisy Corran, and Banga O'Deluga gave Harry Potter two Beater's bats in exchange for six Gobstones while in the Paved Courtyard.
