The first traveler was a drone—a titanium sphere packed with sensors. It drifted into the pearl-white membrane and vanished. For three agonizing seconds, nothing. Then, the sphere returned, but it wasn't the same. Its surface was etched with unfamiliar constellations, and it hummed a tune that sounded like a lullaby sung by a dying star. The data feed was a flood of impossibility: a sky with three suns, a forest where gravity worked sideways, a city built from solidified sound.

It was a fishing trawler in the Pacific that first reported it—a second boat, identical to theirs, passing through them like a ghost. A child in Mumbai woke up with a memory of a birthday party she never had, in a house that wasn't hers. People began glimpsing doppelgangers in reflections, walking just a step behind.

The Nexus scientists called it “quantum bleed.” Opening so many gates, they theorized, was thinning the membrane between all realities. Our world was becoming porous. And worse, something was leaking in .

The lithium world wasn’t empty. It was the corpse of a civilization that had been bled dry centuries ago by a different species of predator. The sound-city wasn't abandoned; its inhabitants had faded into whispers when their reality’s energy was siphoned. Every empty world was a graveyard.

Aris stood at the original Nexus gate as the walls dissolved. He saw Tokyo layered over a crystalline fortress. Lagos bleeding into a fungal jungle. London flickering between drizzle and a perpetual, blood-red sunset. And through it all, the people—billions of people, all of them human, all of them refugees from the worlds their own greed had punctured.

“It’s not a door to another dimension, Aris,” the project director had said six years ago. “It’s a door to every dimension.”

The first Incident was in the Buenos Aires hub. A woman stumbled through the gate, screaming. She looked exactly like Dr. Elena Vance, the lead physicist on duty—same face, same lab coat, same panicked eyes. But this Elena had a gash across her cheek and clutched a child’s hand. The child was crying in a language no one understood.

Today, Aris proved him right. But he also proved something far more terrifying.
