Skeletal Remains Ambient Hum

A persistent low-frequency hum rises from the skeletal remains scattered across the alien landscape, its vibrational pulse threading through the phosphorescent air. The sound is neither purely mechanical nor organic—an unsettling blend that thrums against bone fragments and fossilized stumps alike. Tegan and Nyssa instinctively track its irregular rhythm, recognizing it as the first audible trace of an unfriendly presence rather than mere environmental noise.
