Mechis III
The group moves forward, led by the droid walkers. Not long after the march begins, a background noise becomes evident. It is difficult to make out, like an empty signal band through an audio emitter. Eventually though, it resolves into a series of distinct sounds: scraping, clanking, whirring, sparking...the sounds of droids in various states of disrepair moving.
The first droid encountered is a torso and the upper arm. It drags itself away from the group by the upper arm. The process is slow, only centimeters at a time. Other droids are scattered across the tunnel. Many are as headless as the first, pulled by a truncated arm or pushed by an abbreviated leg. All of them move toward the core.
