Build your dream cities.
Conjure unforgettable urban worlds with ease, using quick-build tables that cover and inspire every pillar of city life: identity, geography, governance, economy, culture, demographics, and more.
Populate them.
Breathe life into your creations with new District modules, ready-to-use NPCs for every occasion, and detailed quest prompts that ensure every class—not just bards, sorcerers, and warlocks—has a reason to dive into the adventure.
Ruin them.
Unleash chaos with crisis tables for corruption, disasters, and decay. From plague and famine to crime waves, sieges, and full-scale warfare, you hold the power to watch your cities burn… or crumble under their own weight.
Go on Big City Adventures
Explore Angler’s Den and its 6+ Districts packed with Quests and NPCs. Once a jewel of the empire, it is now a smuggler’s haven under pirate-oligarchs and corrupt merchants, its grandeur rotting under peeling paint and boarded windows.
New Class: The Technologist
Invention has a price—and your genius is the currency. Embrace SCIENCE and become a Technologist, a brainiac factotum who can replicate skills, steal spellcasting traits, and even emulate the gifts of patrons and gods—before the inevitable side effects catch up. Lost limbs, strange mutations, unstable breakthroughs… brilliance was never meant to be safe.
Subclasses
Dominate minds and weave intrigue divine as a Sisterhood Cleric. Steal your victim’s dreams with the Dreamer Warlock. Stalk your prey and wear its essence as a Facewearer Ranger.
The flesh is weak! Awaken as an Automaton, organic brain-organelles housed in uncanny metal shells, walking enigmas of flesh and machine. Conquer the halls of urban aristocracy as a Reef Devil, a haughty and refined member of merfolk society. Reclaim the city’s skies as a Vulture, strong and resilient birdfolk of the northern isles.
New Species
All-New Mutation Mechanics
Dive into the infinite possibilities of Change radiation! Embrace forbidden tech as the Enhanced, sacrificing flesh for power. Share your body with an intelligent symbiote as the Infested. Rise scarred but unbroken by Change as the Carcinized, reaching crab perfection. Or embrace forced evolution and become Supermutated.
Eldritch-Tech Weaponry
Unleash your creativity with a collection of strange and wondrous gear, brimming with story and style. Wield the suggestive Ad-Sword, channel raw power through the Galvanizer’s Wrench, or brew chaos with the Reef Devil Mask.
Tonic Magic to Power Your Adventures
Master over 20 new Fallout and Bioshock-inspired spells! Channel raw power with Galvanic Smite, unleash scientific ruin with Arc Welding, or wield unstable genius through the devastating Unleash Change.
Big Empty Blue is a sci-fantasy multimedia adventure set in the Big Blue, a vast ocean planet inhabited by unique creatures and cultures – the free Tritonid Dominion, the savage Vulture raid lands, the ever-expanding Iguanid provinces, and the mysterious Deep Ones. Inspired by The Legend of Zelda, Avatar: The Last Airbender, One Piece, and the works of Studio Ghibli, this massive multimedia project features two graphic novels and 15+ DnD 5E resources and zines for 400+ pages of original, human-made content.
About
The Big Blue is a vast ocean world connected to Earth and other planets through a series of broken portals. The Blue is home to many unique sapient races and cultures that evolved from the seas, the skies, the swamps, and the hollow volcanic lands. The Tritonid Dominion is a federation of trade routes controlled by the tritonids, a race of nomadic sea amphibians. In the West, the aggressive Iguanid Empire promises safety and order in exchange for taxes and obedience. In the north, the brutal Vulture clans rule with an iron fist, raiding, pillaging, and trading the spoils of conquest with nearby populations. In the depths of the Blue, the Deep Ones scheme endlessly, studying old technologies and civilizations to keep their intellectual primacy over the other races.
Amid it all lies the mystery of the statue islands, scattered all over the ocean. And the looming threat of the Helix: an ancient, massive artifact roaming around the Blue and destroying everything in its path.
A Sea of Adventures
The 5E resources set in the Big Empty Blue are packed with hundreds of different player options.
New Playable Species
Dive deep into a vast oceanic world where sapient species struggle for survival, power, and control across the endless tides.
Explore the oceans as a Tritonid, nomadic merfolk who ride the currents with resilience and tradition. Wield cunning diplomacy and advanced technology as an Iguanid, citizens of the influential Cerulean Empire. Dominate the skies and plunder the seas as a Vulture, fierce birdfolk of the raidlands. Adapt and thrive as a versatile Human, a species of primatefolk from a distant world. Gather knowledge and enforce imperial rule as a Korbak, devoted catfolk from a dying planet. Embrace the chaotic power of Change as a Reef Devil, the irradiated, haughty merrows of the Spires.
New Subclasses
Fight the almighty leviathans with one of the setting’s subclasses inspired by eldritch magic and advanced tech. Embrace the divine boon of chaos with the Divine Dominion of Change (in “Witches of the Sea”).
Blur the line between dream and reality with the Otherworldly Patron: The One Who Dreams (in Aryel’s Final Curse – Subclasses and Spells). Or pledge your life to the purge of eldritch beings with the Oath of the Sacred Hunt (in Aryel’s Final Curse – Subclasses and Spells).
Friends and Foes
The Big Blue is a vibrant world where the eldritch and the wholesome intertwine. Navigate the intricate hierarchy of tritonid factions and explore a plethora of deep and complex NPCs. Bask in the cuteness and magnificence of the local fauna, but beware of the eldritch nightmares and technological aberrations below.
Magic Artifacts and Builder Tech
Arm yourself and challenge the foes of the Big Blue.
Embrace tritonid spirituality with Change-fueled artifacts like Kalani’s Stone Paddle and the Reef Ancestors’ Mask, or wield ancient Builder technology like Leviathan Caller and the Orb of Tides.
The Comic Series
The comic series follows Sophia and Quill, a teenage human and a young Tritonid, on a journey to discover the mysteries of the statue island of Odir and its inhabitants – a voyage riddled with revelations, ancient secrets, and dark, hungry omens.
