From publisher blurb:
Rikirta is an integrated fantasy setting with a variety of denizens, locations, races, items and features to explore and interact with.
Included are rules for magic during twilight & lunar conjunctions, espionage, natural disasters, survival in the underworld, in the ocean and on the moons, and optional rules for different alignments and life journeys.
Rikirta maps & rules can be used to enhance your own roleplaying setting, or you can use the whole setting with its own style and conventions. An example convention is creatures from the fire moon are all vulnerable to ice magic, and are driven to consume resources.
