Castle VTT

A portable, offline-first DM and worldbuilding tool. Build worlds, run sessions, share with others and play together, all in one app. License: CC BY-NC 4.0 · Free to use Everything core works **without an account**. You only need one to play online, publish to the marketplace, or download other users' content. /images/general-media/1791564204_7DEx9r3t.webp Worldbuilding - Era Timeline: Split your world's history into eras on a timeline bar and move between them. Each era keeps its own map, pins, nested location maps and day-by-day timeline pins linked to cards and sessions. You can show the same city before the war and after it. - Templates & Packages: Every world is built on a template (D&D 5e is built in) and pulls content from packages. A package is a bundle of cards you can install into any world, link to other packages, or share on the marketplace. Custom templates are coming. - Codex: Schema-driven cards for NPCs, monsters, spells, items, locations and more. Every reference is a tappable link. Pin cards to the top, preview any card with a long press, and search by name, tag, category or text. - World Map: Pins, grid and scale, drawing, fog of war, and nested maps you can walk into (districts, dungeons, taverns). - Mind Map: An infinite canvas with linked nodes, workspaces, freehand drawing and undo/redo. /images/general-media/1791564252_TB7zwrCp.webp Running the Session - Second Screen: Give the table its own view. Pop out a window onto a second monitor, cast to a TV or projector, or project into every connected player's app. You choose how battle maps, images, cards and PDFs go out. Fog of war and hidden tokens stay hidden. - Battle Map: The session screen *is* the map, with the encounter panel and event log on top. It has layers, fog of war, AoE templates, 5e diagonal rules, creature-sized tokens, shapes and text, a DM-only layer, hidden tokens, movement trails for the round, and two maps joined into one. - Combat Tracker: Initiative, HP (with hit-dice rolls), conditions, turn order and an event log. - 3D Dice: Dice roll across the screen with named styles. Skills and saving throws roll from the character sheet with one tap. - Soundpad: Layered ambience with gapless loops, fades and ready-made soundpacks. - PDF Library: PDFs kept inside the world, opened in tabs and shareable with players. /images/general-media/1791564292_BnuuXJTS.webp Characters - Full 5e rules: Species, class, subclass, background and feats fold into one sheet. Each sense, resistance, proficiency, trait and always-prepared spell shows where it came from. Also covers multiclassing, spell slots, class resources (Rage, Bardic Inspiration, sorcery points…), weapon mastery, and short and long rests. - Character Builder: Pick species, class, subclass, background, ability scores, skills, starting equipment and feats from the SRD and any installed pack. - Level-Up: HP, proficiency bonus and hit dice update automatically. ASIs, feats, subclass and spell picks wait as pending choices. /images/general-media/1791564330_JBRRDNZ4.webp Playing Online - Online worlds: Put a world, package or character online and it stays the same on every device you sign in on. Players see the pictures even when the DM is offline. - Players: Join with an invite code, claim a character, move your own token on your turn, and send dice rolls to the DM's log. Shared cards update when the DM edits them. - .dmtz files: Export a world, package or character to one file and import it anywhere. No account or network needed. Content - SRD 5.2.1: Built in and works offline. - 19 one-tap packs: Tome of Beasts (1–3, 2023), Creature Codex, Monstrous Menagerie, Black Flag SRD, Deep Magic, Tome of Heroes, Vault of Magic, Tal'Dorei and more. - Ready-made worlds: 99 Devils of Uzrah's Palace (Shadowdark), Army of the Damned, The Cold Bounty, and soon our own campaign Aegis Act . - Marketplace: Publish worlds, templates, packages and characters as versioned snapshots with content previews. - Social: Profiles, follows, an activity feed, direct and group chats, and game listings with applications.

Codex Cryptica is an AI-assisted worldbuilding and campaign management tool built around a living knowledge graph instead of a folder of loose documents. Every character, faction, location, and event you create becomes a linked entity, so your world stays connected and explorable as it grows. Genre-agnostic across fantasy, sci-fi, cyberpunk, horror, post-apocalyptic, western, steampunk, and more.

One Realm is an AI-assisted campaign workspace and virtual tabletop built for groups that want to play tomorrow—not spend the week preparing. It turns adventures, source material, and campaign notes into an organized, playable world, helping GMs complete work that might otherwise take hours or days in a matter of minutes. Characters, locations, encounters, maps, relationships, and story events are automatically organized and connected. From there, the GM can prepare scenes, create artwork, manage characters, and run the game through the integrated virtual tabletop. Because everything shares the same campaign context, preparation flows directly into play without rebuilding the session across multiple tools.

GrimFolio is a canvas-based project planner. Map out your campaign as cards, rooms, encounters, NPCs, factions, locations, and plot points, then connect them with labeled paths to show how everything relates. Each card has notes, checklists, and reference images. You can see your whole story structure at once instead of losing threads across tabs and documents. /images/general-media/1780401778_IBYYgMJz.jpgEvery connection is a decision. Collaborate and work with a team. Invite editors and viewers to any project. Track every change, leave team notes, and always know what happened while you were away. Your command center. Ready when you are. When the canvas is done, Production takes over. Schedule your crew, track your budget, run your master checklist, and export everything — all from one configurable dashboard. Grim stays active, reading your full project state and flagging what's not ready before opening night. Every scare has a blueprint. Map your rooms, scares, and actor cues on a connected canvas. Grim helps you pace the experience — flagging dead zones, suggesting beats, and keeping the story arc tight from entry to finale. Build the world. Let Grim run it. NPCs, locations, factions, quest threads — mapped and connected so you can see every moving piece. GrimVision generates concept art from your card notes. Grim tracks the logic so your players can't break it. Plan the arc. Not just the chapter. Plot beats, character arcs, world lore, chapter outlines — mapped so you can see the whole story at once. GrimVision generates panels and scene concepts. Grim keeps your narrative logic consistent across every arc.

It's October 13th, 1999 and the world has ended. Someone, no one is sure who, let something into our world. A kind of infection or corruption that affects both the body and the mind. Animals, people, even mundane objects... all became twisted and unnatural. Some speculate it's a kind of demonic possession, others that it's an alien or even transdimensional biological weapon. In the end, it doesn't matter. The whole world fell apart, twisted from within. The survivors cling to their wretched lives in a fallen world, trying to comprehend the horrors and fend them off for just one more day. The world is in tatters, monsters roam around consuming everything they can, strange occult powers spread among the damned, and even the very air seems tainted. Perhaps the rapture happened and the survivors are being punished because they were found wanting. Perhaps this is some kind of strange terrorist attack from another world. Or maybe it's all nothing more than a cosmic accident, a tragedy of happenstance as something never intended for this world found its way in. Can you survive and fight off the horrors coming from within and without? Description October Twilight is a survival horror/dungeon crawler tabletop roleplaying game for 2 or more players. One player must take the role of the Game Master. This game assumes familiarity with other roleplaying games and so much of the basic flow of roleplaying is not explained. The game is meant to feel like a PS1/PS2 era survival horror game and a post apocalyptic survival game. Food is scarce, ammunition is scarcer, and everything is trying to kill you. In the game, your team has a safe house they come back to between excursions. The safe house lives up to it's name, being safer than exploring the ruins of the fallen world outside your door. But, you burn resources like food and water at the safe house and have to go out to find more. You'll never have enough resources to simply hole up and wait out the end of the world. Touchstones and Inspirations: Resident Evil, Silent Hill, The Walking Dead, Darkest Dungeon, and Evil Dead 2.
