The Four Courts
In this setting, the world is divided into four courts: The Court of Swords, the Court of Wands, the Court of Cups and the Court of Coins. Each one being divinely mandated to run their respective parts of the world.The core religion of this world follows an arch, representing journeys for example from life to death, or from ignorance to enlightenment. The gods of this world, the Arcana, are stations along those journeys, each representing a stage that someone needs to take in their life. Priests and clerics are guides for that part of a persons' life. However, the Arcana are constantly undermined by a demonic force called the Mara, tempting demons of unknown origin, whose seeming goal is to disrupt peoples' journeys to enlightenment by offering immediate power or riches, usually to long-term defect. This is where things like necromancy or demonic infestation come from.
