Bone Skitter

Priests of Calathis once used deep burial wards to keep the dead still and the tomb quiet. When those wards cracked, the leftover death field did not vanish. It gathered loose bones like iron filings around a hidden magnet, creating small, predatory heaps that now skitter through the catacombs. Old excavators claim the first sign is not sound, but the sudden hush that falls over a corridor before the clicking starts.
