Dreamstone corruption
Dreamstone corruption is a metaphysical phenomenon where reality becomes malleable due to prolonged exposure to radiation from certain First World anomalies.
Manifestation
The corruption manifests as an iridescent sheen on materials like stone and metal, transforming their molecular structure. It emits a distinctive metallic sweetness detectable on the air and generates a low, rhythmic vibration. In concentrated form, it can saturate organic matter, causing preserved bodies to reanimate as simplistic "echoes" of their former selves.
Containment
The dwarves of Kazad-Khrom identified lead as an effective barrier against this radiation and established monitoring crypts to track its spread. The corruption represents the tangible, physical influence of the dreaming entity at the heart of the Asymmetrical Mountain.
