- "There is a room in Transylvania Quarters that is kept locked at all times. It contains a force that is at once more wonderful and more terrible than death, than human intelligence, than the forces of nature. It is also, perhaps, the most mysterious of the many subjects for study that reside there. It is the power held within that room that you possess in such quantities and which Mr. Stupid NoHead didn’t possess at all."
- ―Bertha Swenson talking about the Perpetual Concealment Chamber[src]
The Love Chamber is a room behind a door that remains locked at all times. The door cannot be unlocked by lock picks nor can it be smashed by lightning. It is located in Transylvania Quarters. According to Bertha Swenson, behind the door is the most mysterious subject of study of the department, and the most powerful force ever to exist in the universe — which is known as “Love”. It may also be used in attempts to understand and duplicate the protection self-sacrificing love creates.
Because it is always concealed, it is unknown quite what lies inside it. However, there is said to be a large fountain of Amortentia in the room.
