Dungeon Domains

Our highly successful Dungeon Domains line embodies Bolwerk Publishing’s design principles by offering infinitely expandable dungeon maps, accompanied by system-neutral area descriptions that allow you to prep amazing dungeon delves in record time. Awe your players with fascinating locations, clever challenges, and devious puzzles, all steeped in deep dungeon lore. Hand-drawn maps, gorgeous illustrations, bespoke handouts, and virtual tabletop assets are all provided to augment your game even further. All you need to do is add the monsters, the treasure, and the tweaks that make your games unique!

What are Dungeon Domains?

Dungeon Domains are hand-drawn geomorphs representing sections of dungeons, caverns, sewers, or catacombs, fleshed out with flavourful and detailed descriptions of each area as well as a unique legend explaining the dungeon’s history, all to provide GMs with inspiration to create their own dungeon-delving adventures using any system or setting of their choice.

Every Dungeon Domain has been designed to connect seamlessly with any of its sister products, allowing GMs to construct or expand dungeons of any size with minimal effort.

Dungeon Geomorphs?

Geomorphs are dungeon map sections of identical size and shape, where the ingress / egress points always occur on the same, fixed positions along the edges of the map. This feature ensures that, no matter the number, order, or orientation of the selected maps, the entry / exit points always line up, allowing GMs to quickly and effortlessly construct seamless dungeon maps of any size. All geomorphs in the Dungeon Domains line are based on a square 24x24 grid, having a pair of symmetrically spaced connection points along each of the four edges.

Highly Flexible and Universally Compatible

Dungeon Domains take care of the heavy lifting of adventure design, providing GMs with a fully fleshed out environment which they can easily customise to their heart's content! All you need to do to prep for a game is read the module, add the monsters, treasure, and set a handful of test difficulties! What's more: our evocative area descriptions and extremely GM-friendly lay-out should enable most GMs to determine these things almost on the fly!

Here's an example of how you might connect four Dungeon Domains to build an 37-room dungeon almost instantly! 

Written for Players, Structured for GMs

The player experience sits at the forefront of each and every Dungeon Domain's design. Unique locations, dynamic environments, original hazards, traps and puzzles, and a focus on theme aid in creating unique, challenging, fun, and most of all memorable experiences at your gaming table.

     On the GM's side, we make running your best ever games a breeze by providing detailed maps, clear area descriptions, beautiful illustrations, flavourful read-aloud-text, and copious sidebars and designer's notes to help you flesh out the dungeon environment.

100% A.I. Free

Our products do not use A.I. 'art', A.I.-generated writing or A.I. assistance / prompts of any kind. All Dungeon Domains are 100% created by humans, for humans.

Handouts and Extras Galore!

Thanks to an army of enthusiastic Kickstarter backers, each Dungeon Domain comes with tons of extras including player handouts, area illustrations, virtual tabletop files, and even optional sound effects support! 

Take a look at the page spreads below (taken from Riven Catacombs) to check out the GM-friendly layout of our products. The individual map sections even prevent you from having to flip through the book during play.

Riven Catacombs

The Dungeon Domains line inexorably marches onward, with our fourth entry leading your characters deep into the shadow-shrouded depths of the Riven Catacombs!

Centuries ago, the Red Death cast its shadow across the realm. A demonic plague of gargantuan proportions, it felled nearly one-third of the population. Desperate survivors nailed the crimson corpses into hastily constructed caskets and sealed them inside a hidden catacomb within the Complex. Some accused the plague doctors of being overzealous, burying the living along with the dead…

Fane of Ash

The third entry in our ever-growing line of Dungeon Domains features an ancient subterranean temple, ravaged in a violent, fiery cataclysm. 

Legend holds the worshipers attempted to contact Nusku, demon prince of embers, but inadvertently opened a gate to the plane of fire, releasing gouts of liquid elemental flame into the halls of the fane, turning it into one giant blast furnace.

Today, only charred corpses entombed within ashen chrysalises litter these silent, cinder-choked halls where nameless horrors shuffle about in the darkness, patiently listening for the sound of footfalls in the dust.

Weeping Caves

[...] The trail brought the Brotherhood to a dank, dark cavern strewn with the maimed bodies of a hundred elite soldiers, without any trace of their killers or the Countess. Before the brethren could investigate any further, a horrid keening echoed through the tunnels, filling their hearts with terror. It is said that, as they fled the caves, the very walls began to weep tears of blood. Ever since, no sane man has dared set foot in the Weeping Caves. [...]


The second instalment in our Dungeon Domains line takes us to the Weeping Caves: a treacherous cavern complex which has been the site of a great tragedy in ages past. Rolling boulders, slippery slopes, and a pool of acid await!

Shrine of Dagon

The first instalment, Shrine of Dagon, lets player characters explore a flooded shrine dedicated to Dagon amid a sprawl of ancient tunnels and chambers that once housed the cult worshiping the demon prince of the depths.
