The Phantom Thief of Fate

Alright! Let's dive into Year Two and see what chaos unfolds next.

Chapter 5: The Case of the Vanishing Heirloom

Summer passed quickly, and before I knew it, I was back at Hogwarts for my second year.

The moment I stepped off the train, I could already tell something was… different.

The atmosphere was heavier. Students were whispering. Even the professors seemed tense.

It didn't take long to figure out why.

The Chamber of Secrets had been opened.

Honestly? I wasn't surprised. What did surprise me was how fast things escalated.

Petrified students. Fear of the "Heir of Slytherin." Hogwarts turning into a full-blown mystery novel.

And once again, I had no intention of getting involved.

I was here to enjoy the show. Not solve the plot.

…But then, something interesting happened.

It all started when I noticed Ginny Weasley acting strange.

She was pale, jittery, and always looking over her shoulder.

And one day, while I was passing by the library, I saw her drop something.

I stared at it. My instincts screamed at me. I knew what this was.

The thing responsible for this entire mess.

Ginny rushed away without noticing she had dropped it.

I bent down, picked up the diary, and flipped it open. Empty pages.

I smirked. Oh, this is going to be fun.

Later that night, while everyone else was asleep, I pulled out the diary and a quill.

The ink vanished. A few seconds later, words appeared.

"Hello. My name is Tom Riddle. Who are you?"

I tapped my chin, considering my options. If I responded, I'd get sucked into his little game.

...Or I could just skip all of that.

With a casual wave of my hand, I stole the diary's magic.

Tom Riddle's presence vanished instantly.

The pages turned dull. No more enchanted ink. No more Horcrux. Just a very normal, very useless book.

I tossed the diary onto my desk and leaned back in my chair, grinning.

Meanwhile, in the Slytherin Dorms…

Far away, in the Chamber of Secrets, the Basilisk had no idea what to do.

It had been waiting for orders. Commands from its master.

The great serpent flicked its tongue, confused. Where had the voice gone?

…In the morning, Ginny woke up feeling completely normal for the first time in weeks.

She couldn't remember why she had been acting strange.

She couldn't remember anything about the diary.

Because as far as the world was concerned…

Over the next few weeks, I watched Hogwarts descend into chaos.

Students still talked about the Chamber of Secrets. Teachers were on high alert. But nothing was actually happening.

No attacks. No petrifications. No eerie messages written in blood.

Harry, Ron, and Hermione spent hours investigating something that no longer existed.

"Are we sure the Chamber was actually opened?" Hermione asked one day. "I mean… maybe it was just a rumor?"

Ron shrugged. "I dunno, mate. Feels like something should have happened by now, yeah?"

I took a sip of my pumpkin juice, barely holding back a laugh.

Year Two wasn't even halfway over… and I had already stolen the plot.
