The spirit was infiltrating the Matrix with increasing frequency, and seemed to be drawn to it on some sort of preordained schedule. Judging by the timing of protocol problems, configuration discrepancy problems, and system crashes, it was making its presence known once every hour. According to Aziz, the spirit wouldn’t like being inside the Matrix. In fact, it shouldn’t even be possible for it to enter the Matrix at all. The rigid organization of a computer’s light-encoding hardware would confine it, would twist it like a four-dimensional pretzel, then spit it out again. But like a moth to the flame, the spirit kept going back. It was in and out again in a mere nanosecond. But in that nanosecond, it could wreak a lot of damage.
