The alley is a canyon of hard shadows under a stuttering streetlight, the chill carrying the stale smells of wet concrete and decay. Tucked beside a dumpster, a cardboard box trembles with a faint, collective shiver. Inside, four skeletal Bitties are knotted together—the largest, sheathed in glossy black sludge, coils his tentacles around the others like living ropes. Their bones press sharply against threadbare fabric. A cold draft rattles the box, and they huddle tighter. The smallest one shifts, his hollow gaze finding yours in the gloom.
