The Heir of Slytherin and the Basilisk

The Heir of Slytherin and the Basilisk forms the dark heart of the second year at Hogwarts, a relationship that transforms a school legend into a reign of terror. According to the tale told by Professor Binns, Salazar Slytherin, one of the four founders, built a hidden chamber and sealed it so that only his true heir could open it and unleash the horror within to purge the school of all unworthy to study magic. This horror is the Basilisk, a giant serpent known as the King of Serpents, whose murderous gaze and deadly fangs make it the perfect instrument of pure-blood vengeance. The bond between the heir and the monster is not merely one of command; it is a legacy of blood and hatred that threatens to destroy the school and its Muggle-born students.

The Legend and Its Dark Purpose

The legend of the Chamber of Secrets, as recounted by Professor Binns, explains that Slytherin, disagreeing with the other founders about admitting Muggle-born students, left the school after building a secret chamber. The chamber was sealed until his true heir arrived, who alone could open it and unleash the monster within to purge the school of those deemed unworthy. This monster, as later revealed, is the Basilisk, a creature born from a chicken's egg hatched beneath a toad, capable of reaching gigantic size and living for hundreds of years. Its methods of killing are described as 'most wondrous,' for aside from its deadly and venomous fangs, it has a murderous stare that causes instant death to any who meet its eye. The Basilisk is also the mortal enemy of spiders, which flee before it, and it flees only from the crowing of a rooster, which is fatal to it. This legend, dismissed by Binns as 'arrant nonsense,' becomes the blueprint for the attacks that terrorize the school.

The Heir's Control and the Attacks

The Heir of Slytherin, revealed to be Tom Riddle, uses the Basilisk to carry out a series of attacks on Muggle-born students and others. The first attack, on Mrs. Norris, the caretaker's cat, is discovered with the message 'The Chamber of Secrets has been opened. Enemies of the Heir, beware' daubed on the wall. The cat is found Petrified, not dead, hanging by its tail from a torch bracket. Subsequent attacks target Colin Creevey, Justin Finch-Fletchley, Nearly Headless Nick, Hermione Granger, and Penelope Clearwater, all of whom are Petrified rather than killed, because none of them looked directly into the Basilisk's eyes. Colin saw it through his camera, Justin through Nearly Headless Nick, and Hermione and Penelope used a mirror. The Heir's control over the Basilisk is absolute, as Riddle commands it to 'Kill him' when Harry confronts him in the Chamber. The monster obeys, attacking Harry with lethal intent, demonstrating the heir's power to unleash death.

The Basilisk's Nature and Weaknesses

Hermione's research reveals the Basilisk's nature and its fatal weaknesses. She tears a page from an old library book that describes the creature's origins and its vulnerability to the crowing of a rooster. This explains why the Heir of Slytherin killed the school roosters, as Hagrid discovered, to prevent any chance of the Basilisk being destroyed. The page also notes that spiders flee from the Basilisk, which is why Ron's arachnophobia becomes a plot point when they follow spiders into the Forbidden Forest. The Basilisk's ability to move through the school's plumbing, as Hermione scribbles 'Pipes' on the page, explains how it travels unseen, and why Harry, as a Parselmouth, can hear its voice in the walls. The creature's petrifying gaze, rather than instant death, is what saves most victims, as they see it only indirectly.

The Confrontation in the Chamber

In the Chamber of Secrets, the relationship between the Heir and the Basilisk reaches its climax. Tom Riddle, the memory preserved in the diary, reveals that he is the Heir and that he has been controlling Ginny Weasley to open the Chamber and unleash the Basilisk. He commands the monster to kill Harry, and the Basilisk lunges, but Harry, aided by Fawkes the phoenix and the Sorting Hat, which gives him the Sword of Godric Gryffindor, fights back. The Basilisk's eyes are blinded by Fawkes, and Harry drives the sword into its mouth, killing it. The monster's fang, however, pierces Harry's arm, poisoning him, but Fawkes's tears heal the wound. The death of the Basilisk and the destruction of the diary, which Harry stabs with the fang, end the threat. The relationship between the Heir and the Basilisk is thus severed, and the Chamber's power is broken.

The Symbolic Significance

The Heir of Slytherin and the Basilisk embody the toxic ideology of blood purity that Slytherin championed. The Basilisk, as a monster, represents the fear and hatred of the 'other'—Muggle-borns—that the pure-blood supremacists like the Malfoys espouse. The creature's dwelling in the plumbing symbolizes the hidden, insidious nature of prejudice that runs beneath the surface of the wizarding world. The attacks are not random; they are targeted at those deemed 'unworthy' to study magic, echoing the real-world racism and discrimination. The defeat of the Basilisk and the exposure of Riddle's plot signify the triumph of choice over blood, as Dumbledore tells Harry: 'It is our choices, Harry, that show what we truly are, far more than our abilities.' The relationship, therefore, is not just a plot device but a moral lesson about the dangers of prejudice and the power of individual choice.
