Geologist's Primer

Geologist's Primer is a system-agnostic tabletop roleplaying sourcebook that brings real-world crystals, minerals, and metals into game-ready fantasy and modern campaigns.

Inspired by 19th-century field guides, folklore, mythology, and old-school alchemy, this book gives Game Masters and world-builders practical material for treasure, magic items, strange locations, and character-driven discoveries. Its 100 illustrated entries cover magically inclined minerals from around the world, pairing useful geological detail with fantasy-friendly lore. The book also includes primers on alchemy, blacksmithing, and jewel-grafting, plus quest prompts, random gem generation tables, magical and astrological resources, and other tools for building play-ready ideas.
