We're d20MUD, a family of text-based multiplayer role-playing games and the tools that connect players to them. Our worlds span Dragonlance, Forgotten Realms, and Star Wars: different settings, shared enthusiasm for deep character customization, exploration, and stories made with other people.

A MUD is a multi-user dungeon: an online world you explore through written descriptions and typed commands. Bring your imagination, build a character, and discover what happens when your story meets someone else's.

Ready to play? Open the d20MUD web client, select a game preset, and connect. Prefer a desktop MUD client? Use the host and port above. Game sites have setting details and new-player guidance.

LuminariWebClient brings Luminari-compatible MUDs to the browser with a React + TypeScript frontend and a Node.js WebSocket-to-Telnet proxy.

• Read the world: ANSI-colored output, a live minimap, and configurable map and legend panels.
• Keep your bearings: MSDP-fed character details, resource bars, quests, group information, and active effects.
• Make it yours: saved layout preferences, minimalist mode, customizable key bindings, command history, and history-based tab completion.
• Pick your destination: presets for all three d20MUD games, plus LuminariMUD in the world of Lumia, and custom host/port entry.

HUD data depends on what the connected game server supplies. See the client documentation for setup and configuration.

Three worlds sit at the heart of the organization, supported by public game code and browser tooling. LuminariMUD is an external upstream project and an additional client destination.

Players bring the worlds to life. Visit a game site, read its guides, and join the adventure.

Developers can explore the public repositories, reproduce bugs, improve the client, or propose focused changes. Report client bugs through LuminariWebClient issues, with context and reproduction steps. For game-specific reports, use the game's contact page or in-game help. Follow each project's contribution and licensing guidance.

Builders and writers can help shape rooms, quests, characters, and documentation. See the Krynn contact page or Faerûn contact page to connect with the game team.

Your character. Your choices. Our next story.
