Complete Arduin Book One - 1993 - Rules

Arduin is a fictional universe and fantasy role-playing system created in the mid-1970s by David A. Hargrave. It was the first published "cross-genre" fantasy RPG, with everything from interstellar wars to horror and historical drama, although it was based primarily in the medieval fantasy genre.

The Compleat Arduin Book One: The Rules is a supplement in which rules are presented for the world of Adruin.

The Arduin books attempted to add many interesting and notable features to the fantasy role playing milieu. In addition to new rules, the Arduin Trilogy contained unique new spells and character classes, new monsters, new treasures, maps, storylines, extensive demonography, and all sorts of charts and lists which detailed the Arduin "multiverse", many of which were new to role-playing gamers of the time.

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.
