Their journey took the robots through ever stranger landscapes. One evening, at sunset, the sky appeared to be consumed in a silent explosion. They were momentarily alarmed, however neither of them detected any rapid changes in local atmospheric conditions or an increase in EMF. Even so, there was a low-level background noise that defied analysis…
With the sighting of the giant now moved to storage, the robots set up their thermoelectric generator and discussed their plan for the next day. Through their sighting of the giant they had established the plausibility of some of the stories that had been shared with them during their travels. Their course of action was plain: they would seek evidence to confirm (or debunk) other stories of anomalous events and circumstance.
After the giant had vanished into the mists, the pair of explorers continued on their way along the ridge. While they saw no more of the colossus for the remainder of their traverse, their CPUs hummed with visual data (IR, visual spectrum, and UV) collected during the encounter. Prior to embarking on their journey many stories had been shared with them regarding anomalous phenomena in the vast unmapped areas. They wondered what else might be true?
The night-time trek through the forest was a battery-draining affair; servos and gyros worked overtime to negotiate the rooty and rocky trails. As the weak light of the sunrise began to filter through the trees, the robot anticipated being able to deploy photovoltaic panels to recharge before the next leg of its journey.
