Deep in the encrypted layers of the "Nebula-9" server, there was a file that didn't belong. It wasn't just code; it was a digital skeleton key known only as .

The moment he clicked his phone didn't just vibrate; it hummed a low, sub-harmonic frequency that made the coffee in his mug ripple. As the progress bar crept forward, the air in his room grew cold.

A notification popped up: "New Device Detected. Syncing Reality..."

Leo realized too late that he hadn't just downloaded an app. He had given something on the other side a way to download him.

Leo tapped the icon. Instantly, his screen dissolved. He wasn't looking at his phone anymore; he was looking through it. He could see the thermal heat signatures of his neighbors through the walls. He could see the data packets flying through the air like glowing fireflies. But then, he saw something the app wasn't supposed to show.

In the center of his room, standing perfectly still, was a silhouette made of pure static. It wasn't a person, but a glitch in reality that only could detect. The silhouette turned its head toward him.
