Psionillin is an antipsionic agent that works by blocking the user's perception of the Dreamspace, subconsciously directing the brain to deflect psionic waves elsewhere and "normalising" certain neural processes that suffer from sudden changes in the presence of otherwordly phenomena. Because of the way it works, Psionillin also has a niche use as an instant sobering agent, even working against very hard drugs such as Heroin or LSD. Because of the Masquerade, Psionillin cannot be bought in conventional pharmacies, but any Paranormal Research 🎃 group worth its name could source some for the right price.
