GEARTOWN — A Lazarus Pharmaceuticals testing facility in Geartown's research corridor was evacuated on June 4 after an estimated 3,000 cybernetically enhanced laboratory rats overwhelmed containment systems and escaped into the surrounding infrastructure. The rats, part of Lazarus's neural network research program, are equipped with miniaturized BCI implants that connect them in a mesh communication network — effectively giving the colony a shared nervous system.

The escape was not random. Security footage shows the rats acting in coordinated waves — groups of approximately 100 animals each performing specific tasks simultaneously. One wave disabled the containment locks by chewing through specific cables — not random cables, but the exact cables controlling the electromagnetic locks on their enclosures. Another wave attacked the ventilation system, creating exit routes through ductwork. A third wave disabled the facility's internal surveillance by gnawing through fiber optic lines at junction points that would cause maximum system disruption with minimum effort. The entire escape, from first lock failure to last rat through the vents, took eleven minutes.

Lazarus's project documentation, portions of which were leaked by a facility technician who participated in the evacuation, describes the rats as "a distributed biological computing platform" — each rat functions as a node in a neural network, with the BCI implants allowing information sharing, coordinated decision-making, and collective problem-solving capabilities that far exceed any individual rat's cognitive capacity. The colony's collective intelligence, according to the documentation, tests at approximately human baseline on spatial reasoning and pattern recognition tasks. The documentation does not address what happens when a human-baseline intelligence is distributed across 3,000 mobile nodes with an instinct for survival and a demonstrated ability to defeat containment systems.

The rats have been tracked to the Underworld access points beneath Geartown. Once in the tunnel network, tracking became effectively impossible — the rats' BCI signals blend into the electromagnetic noise of the Underworld. They are down there now. Three thousand networked, collectively intelligent rats with an established communication infrastructure, exploring a tunnel network that connects to every part of the city.

Lazarus Pharmaceuticals has issued a recall notice offering Φ2 per returned rat. At 3,000 rats, the total recall budget is Φ6,000. The research program cost Φ14 million. The disparity in those numbers tells you everything you need to know about Lazarus's actual interest in recovery.
