Plenum

Some networks are not built to be maintained. They are built to feed. Linus Gentry is a creature of the digital trenches. A seasoned low-voltage technician, he has spent fifteen years navigating the dusty, forgotten veins of corporate infrastructure. When he receives a lucrative, no-questions-asked contract to replace the aging cabling in the infamous Aethelgard Tower, he sees it as just another "ghost shift" in a dying building.
But Aethelgard is not dying. It is evolving. As Linus crawls into the "plenum"-the suffocating, fiberglass-choked darkness between the ceiling tiles and the floor above-he discovers that the building's cable management is wrong. The wires aren't just tangled; they are warm. They pulse. And the insulation feels disturbingly like skin. What begins as a routine repair quickly descends into a claustrophobic nightmare.
Linus finds IT tickets that aren't requests for repair, but eviction notices for the living. He encounters "vermin" that scuttle through the trays-not rats, but severed human hands performing ghastly maintenance. Trapped in a concrete monolith that views him not as a worker, but as a spare part, Linus must discover the truth about the "Recall" order before he is permanently integrated into the system.
A suffocating, visceral dive into industrial horror, Plenum will make you look at the ceiling above you and wonder: is it protecting you, or is it digesting you?
