Æthereal Gaslight
This setting presents a techno-magical world where ancient arcana merges with emerging science. Airships, railroads, steel vessels, elemental engines, ethereal telegraphy, industrial alchemy, and mass enchantment shape daily life, while firearms, steam tanks, and war-golems transform warfare. The book serves as a companion to the D&D 5th Edition core rules. It provides player material for creating steampunk characters and supports adventures and campaigns set in this age of technological and magical change.
