We are so excited to head into the final stretch of the campaign, and we can't tell you enough how much we appreciate your support! Over 850K raised and counting! THANK YOU!

800K Unlock - Boss Monster Cards
These full-color cards feature custom boss art on the front and game-ready stat blocks on the back for easy reference during play.



We're hard at work converting Book One into a fully featured Foundry VTT module, and we wanted to share an early peek at one of the digital encounter maps you'll find inside.



As of this update, only a few Collector’s Editions remain. Once they’re gone, they’re gone for good. If you’ve been thinking about upgrading, now’s your chance to lock in this deluxe, crowdfunding-exclusive edition, including foil accents, die-cut windows, magnetic closure screen, and all the premium stretch goal upgrades.




Join us today at 4PM Eastern for a live Q&A with Ian Starcher of Abby Normal and our team! We’re talking Secret Doors, dungeon furnishing design, and more.



We're on the road to $1,000,000! Here’s what’s still ahead:
  • $900K - Digital Boss Battle Map Pack
  • $950K - Level 20 Adventure PDF: Escape from the World’s Largest Dungeon
  • $1M - Foundry VTT Module for Book Two

Let’s finish strong - share the campaign, tell your friends, and help us unlock the final tier of the World’s Largest Dungeon!

The Path to $1,000,000! Only One Week Remains.
9 months ago – Thu, Jun 19, 2025 at 07:41:42 AM

Good morning, Delvers! We are one week out from the close of the World's Largest Dungeon. We have high hopes of surpassing the $1,000,000 mark and unlocking numerous impressive enhancements to the campaign. Please keep sharing and spreading the word!

Don't miss your chance with the Dungeon Master Tier and Limited Collector's Edition. 

Maps

Many of you have inquired about the maps. There are several map-related offerings in the campaign now!

Region Maps: Anyone receiving a box set will get a Folio of Fold-Out Maps: A beautiful tri-fold tome of all 16 dungeon region maps protected in easy-access pockets. The World's Largest Dungeon is massive, so the maps in this set are strategic maps, not tactical. However, they have been redrawn and enhanced, featuring new artwork and design.

🔓Unlocked High-Resolution Digital Maps: All backers will receive the region maps in high-res digital format

Tactical Maps: We have just committed to converting Book One to Foundry VTT, and that is available as an addon now. This will also include ~32 tactical maps (More or less, ~8 maps per region, to be determined) developed by Metamorphic Digital Studio. That means +~30 tactical maps if we unlock Book Two VTT. 

Boss Battle Maps: At 900k, all backers will additionally receive 16 digital battle maps. Keep delving, adventurers... we're almost there! 
 


Stretch Goals

We have unlocked 15 Stretch goals and are still on the climb! If you are coming late the campaign, check out all the amazing stuff we've unlocked! From book upgrades to free digital rewards, this campaign has truly surpassed all expectations.

Meet the Bosses from Book Three (Regions I-L)
9 months ago – Tue, Jun 17, 2025 at 05:37:18 AM

🧱 Horrors Below, Fire Above: Meet the Bosses of Book Three

Book Three of the World’s Largest Dungeon plunges you into cursed labs, fire-scarred lairs, drowned ruins, and sunless seas: each ruled by a monstrous presence. These seven bosses are legendary foes brought to life in stunning detail with custom miniatures, ready to take their place at the center of your next epic encounter.


🐐 Anguish – The Chimera

Forged in a blasphemous lab from dragon blood and abyssal bile, Anguish is a chimera of rage and ruin. Three snarling heads, a venomous tail, and flesh that ripples with unstable power. Anguish is the stuff of fever dreams. This towering creature combines bestial brutality with chaotic symmetry: a visceral sculpt with snapping jaws and twisted anatomy that dominates the table like a living weapon.


👁️ Madness – The Draconic Gibbering Abomination

Born of the same foul ritual as Anguish, Madness is the surviving psychic echo: a protoplasmic ooze with draconic essence, sprouting teeth, eyes, and whispers that shred the mind. It doesn’t speak. It consumes. A coiled, sprawling mass of slime, fangs, and gibbering mouths, Madness is equal parts boss and battlefield hazard. Its mini is perfect for any scene where “What is that?!” is your desired player reaction.


 

🔥 Tyrus, Devourer of Kingdoms aka Scorch

The red dragon so powerful even the gods feared to slay him. Imprisoned in magical ice, he slumbers no longer. The Pyrefaust quakes as Tyrus stirs. Towering over parapets, wings poised in preparation, and chest regal and proud, this colossal dragon mini is your campaign’s jaw-dropping centerpiece.


🧙‍♀️ The Hag Coven

Three ancient hags plot the downfall of all who dwell in the flooded halls of the Shallows. With their eyes on the dragon’s throne and their claws in every dark corner, these crones are the Region’s true masterminds. A trio of unique, menacing hags each sculpted with distinctive spellcasting poses, charms, and cruel glee. They’re more than bosses, they’re campaign archvillains.


🐙 Mahg’Gog, the Half-Fiend Kraken

Tainted by abyssal power, this gargantuan kraken rules the sunken Deeps. His army of mutated sea beasts waits only for his command to surge upward and drown the surface. Tentacles writhe around a demonic core, glowing eyes peer from beneath inky depths, and chitinous suckers adorn his otherworldly frame. Mahg’Gog is a full-on kaiju-level finale.


The complete set of 18 Boss Miniatures is available as its own pledge level, and is included in the Legendary Explorer and Dungeon Master pledge levels. Individual Boss Miniatures are also available individually as Add-ons, so you can have a Draconic Gibbering Abomination painted in each of the chromatic dragon colors or field a squad of driders against your players.
