The Dungeon of Du'unix

A Mountain That Shouldn’t Exist

Your party is summoned by Balthasar Eisenheim and Astinar Merricoss, scholars and seekers who believe something dire is stirring beneath Mu’uz Derron, the so-called “mountain” north of Darkenhaven. In truth, it is no mountain at all… but the inverted corpse of the skyborne city of Telsenthradd, crashed to earth in the Woe of Ruin and left to decay in the Deadhills.

Following a trail of visions, rumors, and a pendant that points the way, your heroes must venture deep into the mountain’s guts, through tunnels crawling with abominations, cultists, and restless dead, to confront the Cult of the Hollow Moon, and stop them from awakening a once-dead leader armed with the knowledge to reshape the boundaries between mortality and undeath.

And if they fail, what rises may not be content with simply ruling from the shadows.

Immersive Tales. Innovative Design. And Art for… Everything.

At Gooey Cube, we don’t just create adventures. We craft unforgettable tabletop experiences. Our games are meticulously designed to immerse Game Masters - and their players - deep into the shadowed, broken world of Zyathé...

And give GMs everything they could possibly need to weave truly epic tales with ease.

It all starts with story.
Our adventures are rich, sprawling, and emotionally gripping… lovingly crafted for roleplayers who crave more than dungeon crawls plagued with random encounter charts. Written to draw GMs into the narrative just as deeply as their players… each tale is brimming with mystery, danger, and character-driven stakes that evolve over sessions of gameplay.

Prep less. Play more.
Every Gooey adventure comes fully loaded with ready-to-run content: an Adventure Book, a GM Reference Book, gorgeous full-color maps, NPC portraits, item cards, handouts, and so much more. Our unique two-book design keeps the story text and stat blocks side-by-side, so you’re never flipping pages or fumbling for details.

GMs often report saving up to 70% or more of their usual prep time.

A world brought to life. Visually.
We believe players deserve to experience the world they’re adventuring in. That’s why we always include human, hand-crafted art for virtually everything… be that towns, taverns, treasure, monsters, or mysterious strangers. Every visual has a purpose. And every moment is designed to immerse.

Intriguing characters. Deep-rooted lore. Gooey rewards.
From backstory-linked NPCs and game-enhancing extras… to narrative-driven not-so-random encounters... everything contained in a Gooey Cube adventure is meant to make your games more engaging, more immersive, and easier to run.

This isn’t just tabletop. This is storytelling… The Gooey Way.
