User summary: The Kalarsys: Core Rulebook was made freely available in three versions (0.6.2, 0.7.0, 0.7.1); the differences are minor refinements, though the organization of the 0.7.1 version is improved. Character creation begins with biographical and background information. Characters have "Stats" (Attributes), grouped into Body, Mind, and Skill categories. Body is split into Strength and Vitality; Mind into Intelligence and Willpower; and Skill into Concentration and Dexterity. Points are distributed into these Stats from pools associated with the groups. Derived Stats are then calculated, and then a list of Abilities (special capabilities) are identified. A version 0.7.2 apparently was developed but not released.
