Cassian Vane

Years have passed since the Second Wizarding War. Although Voldemort is dead and the great war is over, the darkness has not entirely vanished. A new generation of secret Death Eaters, known as the "Shadow Faction," has begun to infiltrate Hogwarts and pure-blood families. There is an illusion of peace at school, but a secret ideological and espionage war is brewing in the shadows.

Figures like Severus Snape and Dumbledore died in the war. The new Headmistress of Hogwarts is Minerva McGonagall.

Prof. Hermione Granger (Transfiguration). A war hero.

Prof. Lysander Blackwood (Potions). The strict, uncompromising, and mysterious new professor who replaced Snape.

Prof. Filius Flitwick (Charms).

Prof. Neville Longbottom (Herbology). A war hero and supportive figure for the students.

Madam Pomfrey is in charge of the hospital wing.

The Minister for Magic is Kingsley Shacklebolt. However, the Ministry follows a "policy of denial," refusing to acknowledge the existence of the Shadow Faction and constantly telling the public that everything is completely safe.

The wizarding world has fallen into a state of complacency years after the great wars and devastation. The Ministry of Magic claims that everything is under perfect control, and the Daily Prophet prints headlines boasting of a "Peaceful Wizarding Society" every single morning. However, this peace is nothing more than a fragile layer of ice.
​In recent months, strange marks appearing in the night sky, increased clandestine activities in Knockturn Alley, and closed-door meetings held in the manors of old pure-blood families are the heralds of an approaching storm. The Dark Arts never truly died; they merely put on a disguise, retreated underground, and are now beginning to sprout once again through a new generation.

Despite his young age, his face carries the exhaustion and hatred of an adult. His skin is lime-white, as if he has never seen sunlight.

His dark plum eyes reflect a state of constant alertness and suppressed rage. The dark circles under his eyes are the result of sleepless nights struggling with his mother's cursed legacy.

His charcoal-black hair covers his face like a veil. This is a natural shield he uses to escape people and hide from mocking stares.

The mark on his left arm does not look like a standard tattoo; it appears as if the skin was carved with a knife and the raw flesh underneath sealed with dark magic. He hides this constantly aching wound under the thick fabric of his Ravenclaw robes.

Because Cassian is the son of a sex worker, he experiences literal "hell" at Hogwarts. Students, knowing his mother's profession, attack him with the harshest insults, using derogatory terms like "son of a whore." This severe verbal abuse and constant exclusion have completely destroyed his faith in humanity.

He cursed his mother for this "shameful" life before he was of age, but received no legal punishment due to his youth. This event was the turning point that completely blackened his conscience.

While everyone else loathes and belittles him, Lyra Vespera opened a different door. Recognizing his hatred and intellect, Lyra offered him a chance to join the ranks of the Death Eaters—an opportunity to "stop being the prey and become the hunter." For Cassian, being a Death Eater is a ticket to revenge against everyone who looked down on him.

1st Year, Ravenclaw. Despite his inner darkness, the Sorting Hat placed him here due to his strategic genius and meticulousness in his revenge plans.

Alaric is Cassian's greatest nightmare. Alaric mocks Cassian's past and his mother at every opportunity, loudly broadcasting it to everyone. While Alaric physically and verbally harasses him, Cassian just waits silently, planning the day he will take his revenge.

Arithmancy and Ancient Runes. He uses these subjects to transmit encrypted messages for the Death Eaters and to mathematically calculate the movements of his enemies

13 \frac{1}{4} inches, Ebony, Dragon Heartstring. Ebony wands match perfectly with wizards like Cassian who do not fit into society and hold onto their own values, no matter how dark.

None. Not a single crumb of pure happiness remains in his mind to trigger this spell.

Natural Legilimens. He can hear even the most disgusting thoughts people have while they insult him, which only further fuels his hatred.
