At Rapier's Point is a Genre Book for Rolemaster which is essentially a campaign book or sourcebook for role-playing adventures in the era of Musketeers, chivalrous outlaws, and masked avengers during romantic 17th century Europe. However, much of this information could probably be adapted to pirate, Zorro, or Robin Hood-style campaign.
The book includes four adventure scenarios, mini-scenarios, and adventure ideas.
The Rolemaster supplement provides five new professions: the diplomat, the nobel de robe, the poet/actor, the religious dissident, and the scientist along with a number ideas for stereotypical characters of the era.
The book includes information for firearms and grenades, weapons of the era, vehicle (coach/sailboat) maneuver charts, and information about 17th century culture.
