Department of Mysteries

This mysterious department carries out most of it's operations in total secrecy. The wizards who work here are called Unspeakables. The department works to uncover the secrets of death, time, thought, and love, among other things, and record prophecies whenever they are made.
The Thought Chamber - A long room in which brains swim in a green solution.
The Space Chamber - A dark room full of planets floating in mid-air. Visitors may find themselves floating as well. Includes the planet Uranus and the planetoid Pluto.
The Death Chamber - A large, square room with stone tiers leading down to a pit in the centre. In this pit is a dais, on which stands an ancient arch with a tattered curtain hanging from it.
The Time Chamber - A room in which various time-related devices are kept, such as clocks of every description and Time-Turners It also contains a mysterious bell jar, inside which anything will grow steadily younger and younger, then slowly return to its original age in a never-ending cycle.
The Hall of Prophecy - A giant room with over a hundred rows of shelves, where recordings of prophecies are kept.
The ever-locked room - A room behind a door that remains locked at all times. Behind that door is the most mysterious subject of study in the Department.
