ADAN
Adan: In the Ars Theurgia, Adan is a demon who serves in the court of the infernal prince Usiel. He is a revealer of secrets, and he also has the power to hide treasure so as to protect it from thieves. He serves only during the hours of the night, and he will only manifest during this time. He has forty lesser spirits that carry out his commands at all times.
