Jayvan Lee is a half-blood who entering their first year at Hogwarts. After the battle, pure-bloods are hated on by muggle-borns; after the half-blood leaning muggle tell them why. But they are a 50/50 half-blood, stuck in the middle, no-where to go. Even though they are only in their first year, they create the HHR army to prove that blood status does not matter as long as they all get along.
