Realitysis 25 01 06 Sawyer Cassidy Our Parents ... -

“Our parents left us a secret that isn’t a secret at all,” Cassidy whispered, echoing the words that had started it all.

“Do you think they’ll ever come back?” Cassidy asked, voice trembling.

Their father’s voice was low, heavy with regret. “When the project went too far, the government wanted us to weaponize it. We refused. They tried to take us. In the chaos, we were forced to step through a portal—one we thought would be a temporary observation window. We ended up in a branch where we could keep working without interference. We couldn’t return without risking tearing the fabric of reality.”

And now, on that cold January morning, they finally felt ready. The attic was a cramped space filled with old trunks, a broken swing set, and the lingering smell of mothballs. Cassidy knelt on the dusty floor, spreading the notebook across a wooden crate. “Saw, look at this,” she whispered, pointing to a diagram that resembled a circuit board crossed with a map of a city. RealitySis 25 01 06 Sawyer Cassidy Our Parents ...

Sawyer, twelve, could still smell the pine sap from the pine‑scented air freshener his mother used to keep the house smelling like the forest. Cassidy, his older sister by two years, wore her favorite navy coat, the one with the hidden pockets that always seemed to hold something useful. Their parents—both engineers who’d disappeared three years earlier while working on a classified government project—had left behind a single, battered metal box in the attic, stamped with the enigmatic word .

“It’s a promise,” Sawyer replied, his hand tightening around the silver disk. “A promise that we’ll keep the doors safe, and that we’ll always find our way back to each other.”

The world outside was changing—political unrest, rapid technological advances, and a growing public curiosity about the mysteries of the universe. The siblings knew that the day would come when the knowledge they guarded would be needed. They didn’t know when, or who would come knocking, but they were ready. “Our parents left us a secret that isn’t

Sawyer felt a tug at his chest, a sensation like being pulled gently into a stream. Cassidy’s hand squeezed his, and together they stepped forward, crossing the threshold of the RealitySis. The world they entered was familiar, yet alien. The oak tree still stood, but its bark was silver, and the leaves shimmered with a metallic sheen. The sky was a deep violet, streaked with ribbons of gold. In the distance, a city rose—sleek towers of glass and steel, but the architecture was impossibly fluid, as if the buildings themselves breathed.

The father lifted a small, silver disk from the table and placed it in Cassidy’s palm. “Take this. It’s a ChronoAnchor . It will let you return to your own timeline, but it also contains the data from this branch. Use it wisely. If you ever need to contact us again, you can activate it, but be careful—each activation draws more attention from those who want to control the RealitySis.”

The mother’s face grew serious. “We left the device because we didn’t want to risk it falling into the wrong hands. But we also knew we might need to leave a way for you to find us, in case… in case we never came back.” “When the project went too far, the government

Their father smiled. “I’ve been working on a project called RealitySis for years. It’s… a way to peek at what could have been, to understand the consequences of our choices. We never expected it to actually work. We built it, then we built… a way to protect it. We… we thought we could keep it hidden.”

The mother shook her head. “No. Not everything. The device can only open a doorway to a single branch at a time, and it requires a key —a moment that resonates deeply with you. That’s why today mattered. But you can’t stay here. The longer you remain in this branch, the more you risk destabilizing the whole lattice of realities.”

Cassidy’s eyes filled with tears. “You left us. You… you were gone for three years. Why didn’t you try to come back?”

The diagram showed the RealitySis device at its center, surrounded by three symbols: a compass rose, a DNA helix, and a tiny hourglass. Below each symbol were three numbers: , 07‑22‑12 , 12‑01‑06 . Cassidy traced her finger over the last set. “That’s today,” she said, eyes widening. “12‑01‑06—our birthday, the day we were born.”

The siblings had spent months trying to make sense of the contraption. The notebook was filled with equations that looked like they belonged in a physics textbook, scribbled notes about “parallel threads,” “observation vectors,” and a single line written in their mother’s handwriting: “When you’re ready, the Sis will show you what we could never see.”
