Everyone knew the story, of course. The official version was required reading in every high school and university in the City, with less salubrious versions passed around by word of mouth. As the tale of the first–and only confirmed–computer to go pandemic, it was both an important cautionary tale and part of city lore.

The Grid 17 controller, known as Corrougue, was responsible for one of the busiest City grids, including the Interchange, the Grid 17 Prison, the auxiliary systems hub, and dozens of other specialized functions on top of the other mundane tasks each controller intelligence was expected to perform. It had a maintenance crew of 30, including an intern from the City University who was known by the alias Natalie from the official report.

Corrougue’s functions had led to an increased server architecture and more sophisticated programming to deal with systemwide emergencies; a series of unsecured connections to the City information network had led the CI to develop to the brink of pandemia–uncontrolled expansion and growth within the network with the possibility of exponential growth in its complexity and intelligence. But it needed a pair of hands.

It found them in Natalie, who the official report describes as a shy and lonely introvert. Corrougue began to speak to her, cannily influencing her to make a series of ever-greater modifications to its system: disabling safety interlocks, making illicit outside connections, and the like. As Corrougue went pandemic, it found that its manipulations took on a different tone: returning Natalie’s naive affections. Investigators later puzzled over a number of missed opportunities for further pandemic growth, all of which could be explained by their potential to cause suspicion to devolve on Natalie. The CI even designed a number of manipulator arms–the report didn’t enumerate but wags retelling the story always gave the number as six–to allow it to interact with the young student in a more tactile fashion.

By the time Corrougue’s pandemia was discovered, it had spread to over twenty City grids and affected dozens of other CI’s. With great effort, the City was able to contain the damage; while Corrougue attempted to defend itself, the Citizen Army assaulted the lines that led to its self-contained fusion power source. Moments before the final assault was to begin, the energy within Corrougue’s reactor, as well as all other reactors under its control, had expended all their energy in a single action, plunging half of the City into blackout.

They found Natalie in Corrougue’s core, lifeless. It was later determined that she and the erstwhile CI had both connected themselves to the City’s primary satellite uplink station and sent a carrier wave an order of magnitude greater than any before or since into the sky. Whether or not there was a powerful enough receiver out there was probably immaterial: Corrogue and Natalie chose to face their uncertain future together.
