Harry James Potter (born 31 July, 1980), also known as Knight (while in his animagus form), was a pure-blood wizard, child of James and Narcissa Potter, twin to Daniel Cygnus Potter and brother to Rose Andromeda Potter. Harry attended Hogwarts School of Witchcraft and Wizardry from 1991 to 1998, and was the first known Potter to be Sorted into Slytherin. He would be one to be chronicled in history as he challenged the age-old traditions of Hogwarts and facilitated a revolution of ideals that united the school.
