In some of the areas through which they moved, the Matrix imagery was muddied, the sharpness of line in the constructs less than standard. At the first few nodes where the phenomena was obvious, the Jiro icon paused, seemingly interested in the effect. This was another clue that the intruder was an outsider, for every Renraku decker was familiar with the fuzzy areas that had become increasingly common along the datalines of the Raku architecture. The imagery-haze phenomena were random in duration and location, seeming not to affect computer performance. None of the deckers knew the origin of the disturbances, and their reports had drawn nothing more than a directive to continue logging all encounters with the phenomena.
