Hogwarts is known, among many other things, for putting underage wizard students through life-or-death situations. During the second installment of the Harry Potter saga, The Chamber of Secrets, it is revealed that Salazar Slytherin, one of the four founders of Hogwarts, built a secret chamber that wouldn’t open until his heir arrived at the wizarding school. Right as Harry starts his second year of wizarding classes, the chamber, of course, opens, unleashing panic amongst the students, particularly muggle-borns, and raising the question: who is the heir of Slytherin?
