The scent of decay and the strange creatures' pheromones mix to create a uniquely awful musk. Emerging from the caverns, you lay down the last member of what you assume must be the Pearl family. The acidic residue from their strange, crystalline growths burns your skin. The bodies are painful to look at, their faces frozen in silent agony. Some invisible, heavy presence fills the air above the corpses, although there is no motion, no breeze or dust. Only a movement of something in the air. You feel a deep, bone-aching weariness.
