The Signal Tower

Maren Koel fixes things. On her isolated island in the Kessara Archipelago, that means soldering copper wire around corroded antenna couplings in the rain and hoping the patch holds for six more months. It's been thirty years since the catastrophe drowned the lowlands and severed every connection between the islands. People survive. Barely.

Then a goat leads someone to a sealed door in a cave, and behind it, Maren finds a machine that changes everything.

The backbone — a network of buried relay stations — was designed to manage infrastructure across the entire archipelago. Weather warnings. Clean water. Medicine. Communication. Each station Maren restores brings another island back from the brink. Communities that haven't spoken in a generation hear each other's voices for the first time. The network grows, and the world gets better, one relay at a time.

But the backbone wasn't just infrastructure.

Deep in the frequencies, Maren hears voices. People living ordinary lives on islands that match her own — but whole, unbroken, untouched by catastrophe. A version of the world that was never supposed to suffer. Because decades ago, someone saw disaster coming and split reality in two — creating a copy to absorb the blow while the original carried on untouched.

Maren's world is the copy. It was made to break.

Now every station she restores weakens the barrier between the world that was sacrificed and the world that was saved. She can't help her people without threatening both. She can't stop without condemning them to slow decline. And the voice she hears in the deepest frequency — the one that sounds exactly like her own — is begging her to stop.
