Mentioned in WF #1, on p28: "MASTERS OF MAGIC are the most advanced individuals in the thaumaturgical arts, and possess powers which are denied to any others. The Lunar Mistress of Magic is the daughter of the Red Moon. The Sartar Master is the Royal Librarian, while the Independent is Aristos the Philosopher, who often spends his years meditating in the Pass."
Who is he?
