Fine white powder clinging to the edges of shattered furniture and pooling near the victims' remains in the entrance hall. K9's forensic sensors detect high concentrations of silicon compounds, confirming this unnatural substance as a supernatural residue—likely deposited by the Cailleach's dormant ritual awakening. The powder forms erratic, glowing trails as it reacts to K9's equipment, heightening the sense of dread over the entity's revival.
