About the Noble House Builder

Generate a fully-fleshed out Great House, aristocratic dynasty, or trade syndicate. This engine constructs a ruling bloodline and heraldry, along with the House's entire domain—including their controlled settlements, regional fortifications, and surrounding wilderness territories featuring dungeons scaled directly to your party.

How to Use This Tool

  1. Select Lineage & Power: Choose the sovereign race and Tier of the House to dictate its wealth and geopolitical influence.
  2. Configure Domain: Adjust the sliders to precisely scale their empire—from the number of controlled settlements and fortifications down to the size of their territory.
  3. Scale for Play: Use the Party Size and Party Level sliders to automatically scale the difficulty of dungeons, monster encounters, and hazards within their wilderness territories.
  4. Inject Ethoria Lore: Toggle the Geography & Lore Filter to inject dark fantasy Ethoria lore directly into the settlement, fortification, and wilderness descriptions based on your selected region and biome.
  5. Review the Charter: Switch between the Dynastic Charter and Family Lineage tabs to explore their territory, inspect garrisons, and view the ruling family tree.
