SCP-035(7)
The use of SCP-148 has worked well, causing morale and suicide rates to return to near pre-SCP-035 rates.
However, the material appears to facilitate the negativity within the cell, causing a veritable "Greenhouse Effect" inside. Personnel inside the cell have stated that they feel a heavy sense of dread, fear, anger, and general depression, as well as hearing constant, nearly inaudible whispering upon immediate entry. A prolonged stay causes severe migraines, suicidal tendencies, heavy hemorrhaging of blood vessels around the eyes and inside the mouth and nose, general hostility to others, and for the whispering to increase to almost deafening volumes, intersected by a constant mocking laughter. Exposure of more than three (3) hours inevitably results in the subject falling into a deep psychosis, and attempting to harm either themselves or others. Most spoke in Latin or Greek, despite the fact that several did not previously know how to speak said languages beforehand.
The presence of blood in both word and diagram formations has increased disproportionately, the walls becoming cluttered, and the formations beginning to overlap each other. The substance has proven to be both difficult to clean, and even more corrosive than was originally recorded, with a pH of roughly 2.4. General estimation gives the current walls a life of two (2) months before they will need replacement.
