My buddy is running an elemental campaign with a French/Italian renaissance-ish setting he started a few weeks ago.
Overview is a thousand or so years ago, an elemental mage broke the world by summoning the elemental lords for some reason. It changed the nature of magic so that only elemental type magics work. Landmasses rose and fell etc. Now elemental magics are divided and religious philosophies have sprung up around them. Different countries are aligned with specific elements and the elemental lords have largely unreachable shrines in various countries in which they dwell. Various elemental materials have various properties (ala elemental companion and elemental companion addendum), and an uneasy peace exists between the countries on the continent of Estonisch. Elemental Champions, Storm Magi, Elemental Explorers, and other classes either pursue business or political goals, or explore the ancient jungles and wastelands for lore and wonders of the lost age.
