Dungeon Master Tool

The Medieval Fantasy City Generator (MFCG) is a highly influential, browser based procedural tool created by the developer watabou. Since its debut in 2017, it has become the gold standard for "instant" urban cartography, capable of generating complex, aesthetic city layouts in a single click. In late 2025 and early 2026, the tool received significant updates to its District View and Building Placement algorithms, allowing for more organic street flow and higher density urban "slums" that better reflect historical medieval layouts. Description The Medieval Fantasy City Generator is a "toy" in the best sense of the word—a lightweight, highly customizable application that prioritizes "cool looking" maps over strict geographical simulation. It uses Voronoi diagrams to partition space into districts, then fills them with procedurally generated buildings, walls, and landmarks. Because it runs entirely in HTML5, it requires no installation and is a favorite for GMs who need to generate a "capital city" or "coastal port" on the fly during a live session. System Overview & Key Features One Click Generation Pressing a single key (Enter) generates a completely new city with unique geography. The tool automatically decides where the castle, the temple, and the market square go, providing an instant foundation for a Game Master to build their narrative upon. Procedural District Mapping The 2026 version features an improved "Alleys and Blocks" view. Cities are divided into logical districts—like the Craftsmans Quarter or the Shanty Town—each with its own architectural density and procedurally generated name that can be edited by the user. Dynamic Warp Tool GMs can manually reshape the city by "warping" its boundaries. If you need a city that is long and thin to fit a specific riverbank, or a circular fortress atop a hill, the warp tool allows you to push and pull the city's footprint while the buildings rearrange themselves in real time. 3D City Viewer Integration By exporting a city as a JSON file, users can open their map in the companion City Viewer app. This transforms the 2D layout into a fully navigable 3D environment, perfect for showing players the "skyline" of the city they are about to enter. SVG and JSON Export Maps can be exported as high quality SVG files, allowing them to be opened in programs like Illustrator or Inkscape for further artistic customization. The JSON export ensures full compatibility with other "Procgen Arcana" tools and major VTTs like Foundry. Azgaar's Integration The generator is natively linked to Azgaar's Fantasy Map Generator. When a user clicks on a city in a world map, it can automatically trigger the Medieval Fantasy City Generator to build that specific town, creating a seamless "World to Street" experience.

TableForge is an AI-powered virtual tabletop that runs your Dungeons & Dragons 5e games for you. Create a character, gather your party, and play through a living fantasy world guided by an AI Dungeon Master that narrates the story, runs combat, and reacts to whatever you decide to do. Every adventure generates its own characters, locations, encounters, and battle maps, so you can go from "let's play tonight" to actually playing in a few minutes. No DM, no prep, no scheduling marathon. /images/general-media/1785090300_1dWltGXR.png Full description TableForge started with a familiar problem: a group of friends who wanted to play D&D together but lived in different cities and could never get their calendars to line up. No regular DM, no reliable session night, just a game everyone wanted to play and no practical way to play it. TableForge is built for exactly that situation, whether you're a full party, two friends grabbing an hour, or one person who wants to disappear into a story alone. You create a character, start (or join) a campaign, and play in natural language. The AI Dungeon Master sets the scene, voices the NPCs, calls for rolls, runs encounters, and remembers what you've done, then responds to what you actually try, not just the path it expected. Talk your way past the guard, torch the bridge, befriend the monster you were sent to kill: the world reacts. That player-driven freedom is the point. The AI handles worldbuilding, encounter generation, and narration so the discovery, improvisation, and agency that make tabletop roleplaying worth it stay firmly in your hands. Under the hood, narration and rules are kept separate. A dedicated rules engine enforces 5e mechanics (AC and DCs, initiative, conditions, hit points, death saves) while the AI focuses on story and table feel. That split is why the DM can stay loose and responsive without losing track of your HP or fudging the math: the numbers are handled, so the storytelling stays free. Whether you want a one-shot, a months-long campaign, solo play, or a co-op night with friends scattered across time zones, TableForge runs in your browser (mobile, too!) and is ready whenever you are. /images/general-media/1785090304_bDgGCr3B.png Features AI Dungeon Master Runs the whole DM role: narrates scenes, voices NPCs, sets difficulty, calls for rolls, and resolves the action. It keeps the game moving, so a session feels like playing with a DM rather than filling out a form. Player-driven story The DM responds to whatever you actually try, and your choices carry forward as the campaign unfolds. The generation builds the world; you decide where the story goes. Real 5e rules, enforced A dedicated rules engine handles the mechanics (the d20 system, initiative, conditions, HP, death saves) instead of leaving them to the AI. Every roll is shown openly, so you can trust the result. Tactical combat and battle maps Fights generate a battle map and run by the book, with encounters tuned to your party. The mechanical state stays visible so you always know where everyone stands. Dynamic adventures and campaigns Every quest generates its own premise, locations, NPCs, and encounters. Campaigns persist across sessions, from quick one-shots to months-long stories as you climb toward level 20. Character creation and progression Build a full 5e hero (species, class, abilities, skills, gear) on a sheet that feels thematic, not like a spreadsheet. Level up and your features, HP, and inventory update as you go. Generated scene illustrations Key moments and locations are illustrated automatically, giving each scene a visual anchor instead of pure description. It does a lot for immersion in solo and remote play. Solo or multiplayer co-op Play solo for a focused story, or invite friends to share a campaign. Built for groups who can't get everyone together at the same time. No prep, play in your browser Nothing to install or prepare. Sign in with Google or Discord, make a character, and start playing in minutes from any browser or on your smartphone. Blog TableForge's blog has resources for players interested in using AI as a tool for their adventures: getting the most out of an AI DM, running solo and remote games, and notes on how the platform works.
