Houses of Sheoloth

This sourcebook explores the dark elf houses that rule the depths below the sunlit lands, detailing their nobility, religions, factions, and sources of power. It expands campaigns using the Sheoloth setting with information on major and minor houses, the Game of Bones, and the clandestine Sheathed War. Players can create dark elf characters and join a house competing for influence, while Games Masters receive faction rules, setting material, and suggested write-ups for lesser participants in dark elven society.
