Mystics and scholars mostly. The Arcanum is more interested in studding the supernatural then destroying it. The Arcanum does not threaten any supernaturals but some may fear them because they know a lot about the secrets of the world. They can also be allies to supernaturals who are willing to except or use them. The price of knowledge can be expensive one.

The Arcanum was created in 1885 in London by a number of occultists who found their original organizations annoying and trivial. They decided to form their own organization that was based on knowledge instead of occult ritual nonsense. The Arcanum started to grow as more members were introduced, some with psychic and magical powers. The Arcanum started to expand all over Europe and to America. In 1910 a chapter house was burned down by kindred. The Arcanum went through some problems but continued to grow.

Currently the Arcanum has 300 official members (Journeymen) and 200 associate members. They are world wide but a more focused in Europe and America. Headquarters is located in London (The Foundation House) but has many smaller bases throughout the world (Chapter Houses.) The Arcanum is still a secret organization that look for members who have studied or witnessed the supernatural. Beginning members go threw a time of learning and then become Journeymen to study on there own.
