Battle of the Department of Mysteries
Ministry of Magic Department of Mysteries
Deep within the Department of Mysteries is the enigmatic Brain Room. The room features a glass “Tank of Brains” - a literal tank of active brains immersed in a special liquid. The brains usually lie dormant but can be very dangerous when disturbed. The ministry studies thought and related subjects in this chamber and Grim Fawley is suspected to have spent many hours in the room prior to his disappearance.
