The Rules of Time

Thomas led Elena through the gaslit streets of Victorian London, his pace quick and purposeful. They had spent the last hour in the library, poring over historical records and Thomas's own research into temporal anomalies.

"You're not the first, you know," Thomas said as they turned down a narrow alley. "There have been others who claimed to have traveled through time. Most were dismissed as mad, but I've always believed there was truth to their stories."

"Where are we going?" Elena asked, struggling to keep up in her modern shoes.

"To meet someone who can help. A scholar who has dedicated his life to understanding the nature of time itself. If anyone can help you return to your own era, it's Professor Aldrich."

They arrived at a modest townhouse, its windows dark except for a single light on the upper floor. Thomas knocked three times, paused, then knocked twice more—clearly a signal.

The door opened to reveal an elderly man with wild white hair and spectacles perched precariously on his nose. "Thomas! What brings you here at this hour? And who is this young lady?"

"Professor, this is Elena. She's... well, she's from the future."

The professor's eyes widened, then he broke into a delighted grin. "Extraordinary! Come in, come in! We have much to discuss."

Inside, the professor's study was a chaos of books, papers, and strange mechanical devices. He cleared a space on his desk and gestured for them to sit.

"Now then," he began, pulling out a leather notebook filled with diagrams and equations. "If you've truly traveled through time, you must understand the fundamental rules. First, time is not a river but a fabric. Every action you take creates a fold in that fabric."

Elena leaned forward, fascinated. "And the book I found?"

"Ah, the book. Yes, I've heard legends of such an artifact. It's said to be a key, a way to navigate the folds. But it comes with a price. Every time you use it, you risk creating paradoxes, tears in the fabric that could unravel reality itself."

Elena felt a chill run down her spine. "So how do I get home without destroying everything?"

The professor smiled grimly. "That, my dear, is what we're going to figure out."
