A miniature system and RPG set in Arthurian Camelot. Each figure has a single stat, Prowess, which starts at 1d10 but can be raised to 100. It could be improved with experience.

Damage is based on the action and the difference between the roll and target. The game also included a description of the code of chivalry, some encounter tables, and rules for falling in love. The campaign section suggested that PCs could found baronies, learn magic or develop spiritual power, although very few details were provided.
