Grimoire Games

Hargrave beginning with a series of four adventure modules and two boxed sets.  By the time The Arduin Adventure was published in 1981, the company was experiencing increasing financial challenges, and in 1984 its last publication for many years was 100 copies of the Arduin: A Primer booklet of revised rules; Mathis moved to San Diego and continued to sell products from the company for a few years.  Hargrave continued to publish Arduin material through Dragon Tree Press until he died in 1988, at which point the rights to Arduin returned to Mathis and Grimoire Games. Mathis worked with Mark Schynert to complete the last unfinished Arduin manuscript by Hargrave, and Grimoire Games eventually published it as The Compleat Arduin in 1993 with financial assistance from a games distributor; however the large work was expensive and outdated and only sold less than half of its print run, and the distributor took a loss, and it became the last publication by Grimoire Games.
