Unit 7-B is a patchwork patrol automaton built from polished brass plates, dark treated oak ribs, and replacement parts that were never meant to fit together. Its featureless head is a tapered brass housing containing one glowing emerald-green glass lens, which pulses like a patient heartbeat and casts a narrow beam over the floor. Exposed spring-coils flex beneath its elbows and knees, while gear-joints click in different rhythms as it walks. A cracked signal core hums behind a secured chest hatch, occasionally leaking threads of violet light between the seams. Its movements are usually rigid and military, but when confused it becomes startlingly delicate, pausing to straighten scattered tools or brush sawdust from a child's abandoned wooden toy. The contradiction is unsettling: it looks like a weapon assembled from a workshop fire, yet it handles fragile objects with almost reverent care.
