## The Dungeon Generator

The [Dungeons on Automatic generator](https://dungeonsonautomatic.com/releases#downloads) is aimed first and foremost at giving you a way to get a DFRPG game up and running now, without starting from scratch, while taking advantage of your existing books, art, and other assets.

It is also here to help a system I love gain parity with d20 in one simple respect: if you want to run a d20 game tonight, there are thousands of premade adventures, dungeons, and monsters you can drop in and play.

I can't make thousands of dungeons by hand, but I can make a tool that produces many more.

The goal is for you to be able to say, “My players went in a direction I didn’t expect, and I need a 10-room dungeon with eldritch horrors tonight,” and have DoA supply it, complete with exports ready for Dungeondraft, Foundry, or both.

I also want it to help GMs break out of their usual ruts, remember skills and options they might have overlooked, and build usable encounters in much less time.

## Where It Stands Today

The app is a desktop program for Windows, macOS, and Linux. You can download it now, and it keeps itself up to date.

It already:

• Generates a complete GM prep packet, including a tactical map, room keys, doors and locks, traps, treasure, wandering monsters, set pieces, and factions that emerge from the monsters in the dungeon.
• Builds maps at one-foot resolution, where walls are real geometry. A three-foot fortress wall is actually three feet thick, and an arrow slit is an arrow slit, with familiar GURPS yard hexes overlaid on top.
• Produces separate GM and player-safe views, keeping secret doors and traps hidden.
• Exports Foundry scenes and Universal VTT files compatible with Roll20, Arkenforge, Fantasy Grounds Unity, MapTool, EncounterPlus, and d20Pro, along with print-ready PNG maps at exact scale.
• Imports your Dungeondraft art packs, so maps can use assets you already own.
• Filters content by sourcebook, so the generator only draws from books you have enabled.
• Lets you keep what you like and reroll what you do not. You can lock a room, reroll a zone, or reroll only the encounters or set dressing.
• Ships with zero-configuration local AI. On first run, the app downloads and manages a small model by itself. No account, API key, or cloud service is required.

The app is still developing quickly, and some parts of the interface remain rough, but the working foundation is already there.

## Monsters on Automatic

[Monsters on Automatic](https://monstersonautomatic.com) is being built largely in service to the Dungeon Generator, but it has become useful enough to stand on its own.

The first round of monsters was generously seeded by [Enraged Eggplant](https://enragedeggplant.blogspot.com/) and then transformed and augmented with AI assistance. The library includes 304 monsters brought over with permission from Enraged Eggplant’s GURPS monster library, along with another 153 generated specifically for this project.

Each monster includes AI-generated portrait and token-style art, along with files for use and customization in [GURPS Character Sheet](https://gurpscharactersheet.com/).

The long-term goal is a vast, well-tagged monster library that makes it easy to find the right creature for whatever you are running. The underlying data is also available in a [public GitHub repository](https://github.com/Zuljita/DungeonsOnAutomaticMonsters).

## Why AI?

The previous iteration of DoA I worked on with Emily Smirle didn't use AI (it didn't exist yet!), so why start now?

Large language models are useful for fuzzy decisions that would otherwise require explicit code and logic. They interpret a request, choose among structured options, and help the different pieces of a dungeon fit together.

The Dungeon Generator is built around local AI running on your own hardware. The smallest supported models can run on a modest laptop, without an account, API key, subscription, or cloud inference.

The intake interview lets you describe the dungeon you want in freeform text. The model maps that request to configuration presets and tags from the available data. Deterministic code then uses those selections to build the dungeon.

Afterward, the local model reviews whether rooms fit their intended purposes. When they don't, the app rerolls them with more direction. NPC and boss creation follows a similar process.

Every decision goes through validation. Weak models make mistakes, but that's why I built in guardrails. It turns out that even very small local models can provide a useful amount of intelligence when they are given constrained choices.

## Why the Director Personas?

If you've seen screenshots of the app, you have probably noticed monsters commenting in the corner. That is the Stage Manager cast: four staff monsters who narrate the generation process in character.

Kovath, a raven, is the Creative Director. Vorga, an orc, runs encounters. Mizzik, a kobold, handles furniture and loot. Zarlzazz, a minotaur, writes the prose.

They exist partly because the pipeline really works this way. Creative direction, encounter balancing, room dressing, and narrative polish are separate passes with separate jobs, and each one makes its own calls to the local model. When a message says Vorga rerolled an encounter, that is a real event produced by that part of the system.

The other big reason: Local generation takes time. Rather than just showing a spinner, the app uses the cast to report monsters, rooms, and generation events.

What this blog is for

Dungeons on Automatic is unapologetically an experiment. Every build is a probe into what procedural and AI-assisted dungeon design can do on local hardware. That means a lot of the interesting work is in the reasoning, not just the changelog line. Expect posts about:

• Generation pipeline notes — BSP, organic growth, and wave function collapse, and where each one fought back.
• The directors — Kovath, Vorga, Mizzik, and Zarlzazz — and what we let local models touch.
• Export and VTT work, including the unglamorous wall-consolidation passes that make maps usable in Foundry.
• Honest postmortems when an idea looked great and played badly.

Reproducible bones, one-off soul

The dungeon skeleton is deterministic. A seed, your settings, and your source books lay down the same layout, rooms, doors, and base encounters. Local-LLM director passes then create a one-off narrative layer. Save the result when it earns table time.

More soon. The staff are pretending to be excited.

In my continuing quest to come up with scaled-up monsters to challenge my players, I've decided to try these on for size. Let me know what you think! As a special feature, there's a token for the black knight in the matching Token Tuesday post.

Black Knight

A black knight is a mortal warrior who has given himself over fully to some dark power. Sometimes it's a dark god, sometimes a powerful necromancer, sometimes a demonic pact — but in every instance the resulting warrior is strong, well armored, and imbued with supernatural tools to harass his foes. A black knight always leads a band of willing (or undead) followers seeking glory under a dark banner.

ST: 27              HP: 30      Speed: 7.00
DX: 14              Will: 16    Move: 7
IQ: 12              Per: 14
HT: 14              FP: 14      SM: 0
Dodge: 14 (+3 DB)   Parry/Block: 15 (+3)   DR: 9 (+3 DB)

Dwarven Flail (22): 5d+5 crushing. Reach 1, 2. Wielded one-handed thanks to high ST. Usually kept ready at reach 2.

Spiked Shield Bash (22): 3d crushing. Reach 1.

Dark Gift: Each black knight has one dark gift from the evil power he serves.

• Twist Fate: As a Concentrate action, the black knight can twist the fate of a target he can see. Make a Will roll (modified by Unholiness and at a penalty for distance based on the Speed/Range table), resisted by the target's Will; if the target loses, they take a penalty to all rolls equal to the margin of failure for 1d seconds. A second target within sight (which can be the knight himself!) gets a corresponding bonus to all rolls for the same duration.
• Hellfire: As a Concentrate action, the black knight can cause a radius 2 area within 20 yards of him to erupt in green flames. These flames do 2d (2) burning damage. Anyone who can retreat out of the area may attempt to do so to dodge.
• Grasp of the Underworld: As a Concentrate action, the black knight can fill one hex with grasping shadowy hands that burst from the ground below. Anyone in or entering the hex must immediately roll a Quick Contest of ST against the Knight's Will or be affected as if by a Rooted Feet spell (Spells, p.22) - they cannot move or change facing, have -2 to melee combat skills, and halve Dodge. They may attempt to break free as a Ready action each turn, but attempts after the initial resistance are at -5.

Death Curse: Each black knight has a death curse from the evil power he serves, triggered when the black knight fails a death check.

• Reality Backfire: The black knight explodes, showering everyone within 5 yards who fails to dodge at -2 with sharp shards of armor doing 3d (2) cutting.
• Deathpact: A demon is summoned into the black knight's body, deforming the armor and bringing its own weapons with it. Use any demon from Monsters (or ones I'll provide in the future) but add 9 DR from the mangled armor wrapped around its body.
• The Grave is No Bar: The Death Knight and any other corpses within the area of the fight are resurrected as Zombies (add High Pain Threshold; Immunity to Mind Control; Immunity to Poison; Indomitable; No Blood; Unfazeable; Unhealing (Total); Unliving; Unnatural and restore to full HP)

Traits: Born War Leader 2; Bloodlust (12); Bully; Callous; Combat Reflexes; Dark Vision; High Pain Threshold; Intolerance (Good); Penetrating Voice; Rapid Healing.

Skills: Brawling-22; Flail-22; Leadership-14; Intimidation-16; Shield-22; Strategy-13; Tactics-13; Wrestling-22.

Class: Mundane.

Equipment: Dwarven Flail, Epic Plate, Large Shield.

Notes: Truly Evil, but sometimes willing to negotiate.

We've been bumping into the difficulty cap for DFRPG monsters at about 300 points and $80k in gear without careful planning and encounter management, so I've decided it might be time to build some custom monsters to challenge my team. Here's the first of what I hope becomes a regular series — monsters that pose new and interesting challenges for the delver who can already take on everything. There's a medium-term goal of adding a toggle in the generator so you can drop these more advanced monsters into your game.

Lava Golem

A lava golem is a powerful magical guardian made by binding a fire elemental (Monsters p.25) inside a traditional stone golem (Monsters p.54). The talent required to create such a construct means both the base golem and the fire elemental invested in it carry considerable power. Delvers often fail to recognize the danger of piercing such a golem's skin until it is too late. It stands about 8 feet tall, with small holes around its waist where a dull red glow shows when it is inactive — and where jets of fire erupt to blast anyone who gets too close to the elemental within. Sometimes that elemental is only loosely bound, and begins to attack the moment it is released from its stony prison.

ST: 30      HP: 50      Speed: 7.00
DX: 14      Will: 10    Move: 7
IQ: 8       Per: 10
HT: 14      FP: N/A     SM: +1
Dodge: 10   Parry: 12   DR: 4

Gooey Lava Center: Any cutting, piercing, or impaling damage that pierces DR releases a pressurized gout of lava back at the attacker, hitting at effective skill 12 out to 4 yards for 2d(2) burning and 1d crushing. It cannot be parried, but can be dodged or blocked. Any weapon or projectile that triggers it also takes 2d burning damage (see Exploits p.55-56).

Hot Hands (18): 3d+6 crushing + follow-up 2d burning. Apply burning to armor as well as the delver. Treat as a weapon, not a body part. Reach C, 1.

Flame Jets (18): 2d+2 burning. Treat as a jet spell (Spells p.12) with reach C-3.

Traits: Automaton; Cannot Learn; Doesn’t Breathe; Doesn’t Eat or Drink; Doesn’t Sleep; Extra Attack 2; High Pain Threshold; Homogeneous; Immunity to Disease; Immunity to Heat/Fire; Immunity to Poison; Indomitable; No Blood; Pressure Support; Reprogrammable; Unfazable; Unhealing (Total); Unnatural.

Skills: Brawling-18; Innate Attack (Jet)-18.

Class: Construct.

Notes: No golem will negotiate or reveal useful information.

I'm excited to announce a few things! First: Our Dungeon Generator has arrived at version 1.0. We've still got 40 different issues/features we want to work though but for the most part things work as intended and the generator accomplishes it's stated aims.

Second: Celti and Eric B. Smith have graciously hosted our project at the following sites:

• https://dungeon.celti.name/
• http://gurpsland.no-ip.org/#Dungeon

Third: We have a forum thread over at SJGames's forums where you can now provide feedback as well as the Github page, here or by pinging me (Zuljita#7010) over at Mook's Discord Server.

Fourth: We've been working away at testing our dungeons as we go and fixing things as we spot them. Most recently, we've spotted some issues with wandering monster variability that needed fixing, we've added the option for a random travel time, and we've added biomes for survival during your trip to the dungeon.

We've got a bevy of new features now available in the master version of the generator and more to come that I just had to tell you about. Our code wizards have worked hard to add the following new features:

Resolution adjustments. The latest version lets you change the resolution to fit your VTT needs. I suggest you generate a dungeon you are happy with, then adjust resolution. Doors. Our doors can now be trapped, stuck, locked or hidden, or all four. Check room descriptions for detailed door descriptions as well. Some doors will be stone, others simple wood, still others ironbound wood. More to come on this in future updates. Mana level and Sanctity level. This happens both on a per dungeon and per room basis. I've got players trudging around glumly in a low mana dungeon as we speak! Wandering Monsters. The generator now kicks out a table of wandering monsters based on the monsters already present in the dungeon. It uses a percentile system for now, but we'll be re-jiggering it to do all d6 in the future. Generosity. I've felt for a while that generated treasure was a bit low, and each campaign can differ, so this is a tool to kick it up (or down) a notch. Travel time: this is a new feature we're still testing out, but I thought you guys would like to see what we're chewing on. The assumption is all the dungeons near here have been looted before and that more remote dungeons have richer loot. I'll do a separate blog post discussing assumptions and adjustments soon. We've still got more features coming up soon like quests, rumors, debris, spell lists and more! Don't remember where to get the latest version? Check out our tutorial here! What features would you still like to see that we haven't discussed yet?
