The document begins with a few pages explaining the genesis and history of the High Fantasy Society, essentially a variant Society for Creative Anachronism (SCA) that implemented additional rules to support fantasy elements including magic and monsters. The HFS attempted to be a comprehensive society with combats, fairs, demonstrations, and revels.
The rules specify that players must be costumed. The Battle Game Rules focus primarily on safety and secondarily on a realistic fantasy combat mechanism that distributes wounds to actual hit locations and discusses debility accruing from certain types and locations of wounds. Characters gained "Levels" (1-6) by duration of experience and selected a "Class". Each Class, at each Level, gave certain custom abilities. Several Classes gave access to certain types of magic, implemented as a spell system. A section presents Monster Class rules. The document also includes a fairly length segment on how to construct "safe" weapons.
