Big Empty Blue

Big Empty Blue is a creator-led sci-fantasy multimedia project set on the Big Blue, a vast ocean planet linked to Earth and other worlds by broken portals. Its setting features diverse peoples and cultures, including the nomadic Tritonid Dominion, the expanding Iguanid Empire, the northern Vulture clans, and the mysterious Deep Ones. Across graphic novels and more than 15 Dungeons & Dragons 5E resources and zines, the project offers over 400 pages of original content, including playable species, subclasses, spells, characters, creatures, magic artifacts, and advanced technology.

Its tabletop materials help players and game masters build adventures in a world shaped by political rivalries, ancient secrets, eldritch threats, and the roaming artifact known as the Helix. The City of Sirens project expands the range with an urban-apocalypse campaign setting, a city-creation system, modular districts, quests, NPCs, and rules for crises and destruction. It also introduces the Technologist class, new subclasses, species, mutation mechanics, equipment, maps, and miniatures for 3D printing.
