The World of Gaianar
This d20 roleplaying setting presents Gaianar, a fallen world reduced to a pre-industrial state by wars that devastated its realms and killed millions. Gunpowder and firearms represent the height of practical technology, while steam engines are rare marvels and magic and spiritual forces have returned. The setting is adapted for the Wizards of the Coast d20 system, primarily for v3.5, with notes for compatibility with v3.0. It is provided as a downloadable Microsoft Word document.
