run a game. The Arduin Adventure was eventually written to replace use of the D&D core book. Material from all of these were subsequently used as the basis for The Compleat Arduin (1992), a standalone system. Publication history The original Arduin suite of supplements, dungeon modules, and gaming aids were initially self-published (1977–78), but were then later produced by Grimoire Games. Dragon Tree Press produced four further Arduin supplements in the mid-1980s before the Arduin rights and properties were purchased by Emperors Choice Games and Miniatures in the early 2000s. Grimoire Games Grimoire Games was a publishing company run by Jim Mathis. Active from 1978 to mid 1981, Grimoire Games's primary focus was the early Arduin series of RPG supplements, written by Hargrave. The Arduin Trilogy is the most famous of the Hargrave supplements. Hargrave sold Arduin to one of his players, Jim Mathis, in 1978 and Mathis started Grimoire Games out of a UC campus apartment building in Berkely to publish Hargrave's Arduin material 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 having increasing financial difficulties, and in 1984 its last publication for many years was 100 copies of a free booklet of revised rules for Arduin; Mathis moved to San Diego and continued selling 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 Arduin was brought back to Mathis and Grimoire Games. After finishing Hargrave's unfinished Arduin manuscript, 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Compleat Arduin in 1993 with financial assistance from a games distributor; however the large work was expensive and outdated and only sold less than half of the print run, and the distributor took a loss, and it became the last publication by Grimoire Games.
