An outlawed psychoactive agent. In California it is known as "Grievous Angel". In 85% of experimental subjects it produces acute paranoia and homicidal psychosis.
In order to infiltrate the Sense/Net Pyramid, pranksters of the Panther Moderns called 9 different police departments and security agencies claiming that an obscure sub sect of militant Christian fundamentalists released this agent into the ventilation system of the Pyramid. As a result several NYPD Tactical hovercraft and a BAMA Rapid Deployment helicopter converged to the Pyramid.
