Synopsis:

Reincarnating into the Harry Potter universe should have been a dream come true. But for [FMC's Name], it was a playground for chaos.

Gifted with a magic ability that lets her steal anything without anyone realizing it’s gone, she turned the wizarding world upside down—stealing the Philosopher’s Stone, dismantling Voldemort’s plans, and leaving even Dumbledore utterly baffled.

By the time she left Hogwarts, history had been rewritten beyond recognition.

But her journey doesn’t end there.

With nothing left to challenge her, she sets her sights on a new magical world—one just as full of legends, prophecies, and untold power.

And once again, no one will ever suspect a thing.

The Phantom Thief of Fate

Life at Hogwarts was easy. Too easy.

Classes? Simple. Magic? Fascinating, but nothing world-breaking yet. Socializing? Not a problem—I just blended in, asked a few smart questions in class, and no one gave me a second thought.

Everything was going according to plan.

The only real challenge was keeping myself entertained while I waited for the right moment to steal the Philosopher's Stone. Because let's be honest—waiting for the plot to unfold was kind of boring.

That's why I decided to… make things a little more interesting.

Small changes. Nothing big. Just enough to mess with the story a little without drawing attention to myself.

1st Small Change: Malfoy's First Encounter with Harry

During Potions, I "accidentally" nudged Malfoy's cauldron just as he was about to introduce himself to Harry.

The result? His potion bubbled over, turned a nasty shade of green, and exploded in his face.

Instead of smugly offering Harry a handshake, Malfoy spent the rest of class covered in slimy green goo while Snape fixed his hair. By the time he was back to normal, Harry had already made up his mind that Malfoy was an idiot.

Was it necessary? No. Was it funny? Absolutely.

2nd Small Change: The Troll Incident

I knew the troll was supposed to appear in the dungeons during Halloween, setting up the whole "Golden Trio" moment. But… what if it didn't?

So, when Quirrell ran into the Great Hall, screaming about the troll, I casually stole his wand.

He had no idea. The poor guy patted his robes, confused, while Dumbledore took over.

No wand meant Quirrell couldn't guide the troll to the girls' bathroom. Instead, it just wandered aimlessly until some professors caught it. Hermione never got in danger, Ron never had to save her, and the trio didn't bond over the experience.

They were still friends, but not best friends.

Would this change things? Probably. Did I care? Not really.

I hummed to myself as I walked back to the Ravenclaw common room, satisfied with my work. These were just tiny alterations—nothing too noticeable. The main events were still on track.

But soon, I'd make my biggest move yet.

The moment Quirrell stepped into that forbidden corridor, thinking he could steal the Stone… he would realize something was very, very wrong.
