Build a world. Play in it.
Describe the world in your head—dying empire, space western, haunted coastal town—and WyrdTale invents a system to match: its own classes, skills, and factions, with real mechanics and real consequences. Not 5e reskinned.
No forms to fill out, no wikis to pre-write. You talk about your world and the engine derives classes, skills, factions, and geography—all consistent with your vision.
Every world derives its own system from its own logic—radically different classes, resources, and signature mechanics, because they grow out of your setting, not a 5e template.
Nine powered classes mapped to ability scores (Bruiser, Blaster, Speedster, Shifter, Controller, Psychic, Sensor, Operative, Civilian), four resource pools (Charge, Flux, Psyche, Stamina), and a signature mechanic: The Cache—dimensional storage that freezes whatever you stash in time-stasis. Not D&D classes reskinned.
A different nine (Combatant, Pilot, Technician, Scholar, Operative, Diplomat, Medic, Civilian, and Anomaly): ruin-touched beings who came back from the gates changed, channeling abilities through a resource called Resonance that nobody fully understands.
In a chatbot, the blacksmith exists only as long as the conversation. In WyrdTale, he has psychology, secrets, a home he goes back to at night, and a relationship with you that evolves over time.
You show the binding mark to the blacksmith. He flinches—hard—and turns back to his anvil. Won't explain. Changes the subject twice. Offers you a discount on a sword you didn't ask about.
You return to Garrett's forge. He sees you come in and—for the first time—closes the shop door. He remembers you. Remembers the mark. Something has shifted: he reaches under the anvil and slides a tarnished key across the workbench.
Garrett is an illustration. Here's a real one—from Dark Superhero, one of the ready-made worlds you can open in a minute and reshape, or set aside to build your own. In it you play Luke: nineteen, raised inside the shadow apparatus that quietly runs the city's licensed heroes.
A former resident of the Roost—the hidden facility Luke grew up in—now a field operative for the same apparatus, Dorian offers to mentor him. He's warm, polished, generous with advice. He's on Luke's side.
The web around him is real, too: the charity that placed Luke spent years grinding down the aunt who tried to take him in—paperwork, delays, “respectability theater”—to keep her an unresolved loose end instead of a scandal. And none of it is reserved for a showcase world: the same density of characters, relationships, and factions grows around whatever world you build.
Your system doesn't just start bespoke—it keeps growing. Use “Channel Elements” to create fire walls three times and WyrdTale offers to crystallize “Wall of Flame”—a new skill shaped by your playstyle.
Every relationship tracks dynamics, catalysts, and secrets. Betray the merchant guild and the system remembers why an assassin shows up six sessions later.
Mechanical time tracks dawn and dusk, recharges abilities, and sends NPCs home at night. Visit the tavern keeper at midnight—she's not there.
Real dice rolls, real resource depletion, enemies that fight to win. Defeat and death are on the table.
WyrdTale plays like having an AI dungeon master—you say what you do, it runs the world, the dice, and every character. But it isn't D&D 5e: instead of one fixed ruleset bolted onto every setting, the engine invents a system from your world. Solo or GM-less, anytime, and the world is a file you own—no credits, no metered tiers.
Describe a world and the engine derives its system with you—classes, factions, geography. An hour or so from a blank page to playing in a place only you could have made.
In a hurry? Say you want to play the Dark Superhero demo (or Space Cowboy) and you're in within a couple of minutes—then make it yours: keep the hero, take over any character, or reshape it. A fast way to start; building your own is where the engine really opens up.
Connect WyrdTale to Claude in under a minute:
Add this to your Claude Desktop config file (requires Node.js):
{
"mcpServers": {
"wyrdtale": {
"command": "npx",
"args": ["mcp-remote", "https://wyrdtale.com/mcp"]
}
}
}
Any client supporting remote MCP servers can connect to https://wyrdtale.com/mcp
Recommended: a strong tool-using model—Claude Opus or Sonnet with extended thinking—for the best play. Any MCP-capable agent can connect.
WyrdTale's Game Master runs from an operating guide. Pin it in a Claude Project and Claude keeps it loaded across long sessions—even after hours of play fill the context window. This is the recommended way to play.
At the start of play the GM looks for the line WYRDTALE GUIDE v10 in your Project. If it ever reports the guide is missing or out of date, download it again here and replace the file in your Project knowledge.
