Unseen Masters, a Call of Cthulhu supplement published by Chaosium Inc., has earned author Dr. Bruce Ballon the 2001 Mary Seeman Award for Outstanding Achievement in the Area of Psychiatry and Humanities.

The Mary Seeman Award is given for outstanding achievement for papers, programs or work that focus on Psychiatry and the Humanities. It is presented annually by the University of Toronto's Department of Psychiatry.

Although there were numerous papers submitted for the award, Unseen Masters blew them all away. Dr. Ron Ruskin, Chairman of the Award Committee stated, "An amazing work. It is prodigious, highly creative and extremely original. It was the best of a number of wonderful papers submitted this year."

Unseen Masters is the first horror fiction or RPG book to ever receive an award from a World Health Organization Centre of Excellence and top international Psychiatry department. The book has been given the stamp of academic acceptance and recognition in the medical world.

Unseen Masters has also won the Origins Award for Best Role-Playing Game Adventure of 2001. The Academy of Adventure Gaming Arts and Design presented the awards at the 2002 Origins Game Expo, the North American Games Showcase, in Columbus, OH.

The Origins Award is the highest honour bestowed for excellence in hobby game design. Past winners have included such classic games as Dungeons & Dragons®, Magic: The Gathering®, and Civilization.

Unseen Masters was the first RPG book to become a Bram Stoker Award Final Nominee in the 2001 Alternative Forms category. The Bram Stoker Awards are presented for Superior Achievement in Horror Writing from the Horror Writers Association. In qualifying for the Preliminary Ballot, the book received 31 recommendations, making Unseen Masters the most recommended work across all categories for 2001. The Awards were presented at the Stoker Weekend Convention in New York City on June 8th, 2002.

Unseen Masters is a Final Nominee for a 2002 Prix Aurora Award in the English (Other) Category. The Canadian Science Fiction and Fantasy Association presents the Prix Aurora Awards annually for some of the best work in Canadian SF and fantasy. The Aurora awards are closest to the style of the Hugo awards in the method by which they are selected.

Unseen Masters also received the "Outie Award" for Best Game Supplement for 2001.

The award was bestowed by Ken Hite in his column "Out of the Box."

A special article in issue #14 of "Games Unplugged" magazine was devoted to the author of Unseen Masters entitled "Unseen Master: Bruce Ballon." It details his involvement in horror writing and game design using his psychiatric background.
