How It Works
Counsel
Building Generator, Answered
How do I design a building for D&D?
Pick a type, press Generate, and you get history, a room-by-room layout, and who holds it now — a landmark you can run as a scene or a dungeon.
Can a building be a dungeon?
Absolutely. Generate the structure here, then use the Dungeon and Hazard tools to fill it with threats and traps.
Who lives in the building?
The generator names the current occupants; expand any of them with the NPC or Faction tools.
Build the Rest of the World
One tool is never enough. Chain them — the party never runs out of places to go.
