What is Watabou's Procgen Arcana?

Procgen Arcana is a discovery page for a family of procedural generators. Instead of offering one generic map, it gives worldbuilders several starting points for different locations and story scales.

The collection is useful when you need a quick visual prompt for a campaign, a fictional region, or a setting exercise. Generated maps are starting material, so a game master can still edit, interpret, and expand them for a specific story.

Which map generators are listed?

The public collection exposes several distinct generator categories, each with its own related page and generator entry.

  • Realm and perilous-shores style regional maps.
  • City and village layouts.
  • Cave or glade environments.
  • Dungeon maps for adventure planning.
  • Dwellings and smaller built environments.

Who is this map generator collection for?

It is a good fit for tabletop RPG game masters, fantasy writers, worldbuilding hobbyists, and anyone who wants a visual prompt without drawing every location from scratch. The free procedural approach is especially useful during early ideation, when speed matters more than final cartographic precision.

Best for

  • Tabletop RPG game masters
  • Fantasy writers and worldbuilding sessions
  • Fast visual prompts before detailed mapping

Know the limits

  • A replacement for a commissioned final map
  • A guarantee that every generator fits one campaign system
