Jaiman d20 Campaign
This fan-created d20 campaign setting is set on Jaiman, a continent on the world of Kulthea, beneath the white moon Orhan and black moon Charon. Powerful ley lines cross the land, drawing wizards, summoners, and other magic-users to ancient towers, cottages, and way houses. The setting presents a world in decline, where the remnants of a former golden age include ruined way houses and the disused Essaence Gates. Secretive Navigator Guilds retain knowledge of the gates, while player characters explore the continent and its magical, forgotten places.
