The regular swing of their legs measuring distance day by day, measuring the journey into the unknown with every stride, the robot made note of features and objects encountered, pushing back the borders of the Unknown Areas.
The robot stood a moment, the territory spread out before them, territory waiting to be mapped, documented and known. All previous information regarding the outlying areas were frail structures built on fragmented and noisy datasets. The robot had prepared for this task. After noting the location of what was an unmistakably artificial ring-like structure, the robot walked on, measuring their strides.
After a few hours the robot emerged from the slot canyon and stepped into the waning sunlight. They stopped and removed the map and added some updates. They surveyed the scene stretching out ahead: the canyon had connected the known with the unknown. The robot was… what word would the human have used? “Enchanted” seemed appropriate; the vista would bear much examination.
The wind rushed through the channel cut in the rock with a husky susurrus. The robot logged their measured steps, measuring the angles of each bend in the channel. Periodically they stopped to make notations on the map.
The shared stories were true: the EMF interference in the Unmapped Areas was a significant source of noise, and it was irregular, some areas had stronger fields, some weaker; some seemed to pulse. The robot took the step of installing shielding in their housings and to use dead reckoning and analog tools to build out a map of the Known Areas; to document salients into the unknown and make it known.
After walking a day and a night to reach it, the robot arrived at the foot of the towering monolith. This was the location of the anomalous light source they spotted yesterday. As they approached the monolith, the robot had detected steadily increasing levels of EMF interference; now the noise was so great that peripheral systems were glitching and there was a serious danger of a central system crash. A file system check would slow progress but was necessary. A file system check would slow progress but was nec…
The robot had paused briefly to place its pack on the ground and rearrange its contents. Satisfied with the new weight distribution the robot stood and scanned the horizon. It spotted a bright point of light high up on tall formation. The light was not steady but seemed to flicker and change in intensity at irregular intervals. Having resolved to proceed and investigate the anomaly, the robot recalled the human back in the city having a term for stimuli such as this: “bait.”
The trek across the vast open space was a mindless one: the terrain was flat and featureless and required only passive scanning. A majority of CPU resources and peripheral systems could be idled to conserved power.
Easily visible from a great distance, the smooth, regular shape of the ring-like structure clashed with its rocky surroundings. The robot made careful notations: this was far from any other documented structures and by far the largest artifact found this deep in the Unmapped Areas.
